11 - Cascade—Cascade connections
 
11 –2 
 
The master unit will check the connections, 
and check for the presence of other units in 
the cascade which have had their IDs set 
correctly. The screen below will be shown if 
two correctly-congured and connectred 
slaves are discovered in the cascade.
 
6
 
Press 
 
ENTER
 
 to continue with the cascade 
operations, or, if the number of slaves has 
been wrongly reported, press a cursor key to 
cancel, check connections and settings, and 
re-try.
If no slaves are discovered by the master, the 
following screen appears:
 
7
 
When 
 
ENTER
 
 is pressed (in 6 above), the 
slave units ’ 
 
CLOCK
 
 indicators will go out, as 
the slaves lock their clocks to that of the mas-
ter unit. 
After the clocks have been set, other internal 
settings are communicated between the mas-
ter and slave units. Do not try to add or 
remove units from the cascade. The following 
message appears if a cascade connection is 
broken or a unit is removed (via software) 
from a cascade while this negotiation is tak-
ing place:
 
When turning on a previously-congured cascade of 
units, make sure that the master unit is always turned 
on 
 
last
 
.
It is not possible to turn the cascade function off on 
any unit or to turn the power off on a cascaded unit 
while the cascade is in use. If the power to a slave 
unit is turned off accidentally, turn the slave off 
again, and restart from step 5 (turning the master 
unit’s cascade off and on again to re-recognize the 
existence of the slaves).
The top on-screen button in the 
 
DIGITAL I/
O CASCADE
 
 screen, shown below, is used to 
turn the cascade on or off. If this is set to 
 
OFF
 
, the 
unit is described as being out of the cascade, even if 
it is physically connected as part of the chain.
 
NOTE
 
Do not attempt to turn the cascade on or off 
while the initial “negotiation process ” is taking 
place, as described above. If an attempt is 
made to do this, the cascade setup must be 
re-started from the beginning. If the cascade 
function of a slave unit is turned off while the 
cascade is in operation, the cascade setup 
process must be re-started from step 5 
 
above.
 
Every time the units in a cascade are powered off, 
their cascade status and IDs are memorized. How-
ever, so that the master can negotiate the cascade sta-
tus, it is important that the slave units are turned on 
rst, allowing the master to recognize the slave units 
when the power is turned on. The cascade slaves 
should be recognized, and 
 
ENTER
 
 pressed to con-
tinue using the cascade.
 
11.1.1Selecting busses for cascade
 
In the 
 
CASCADE
 
 screen of a slave unit, it is pos-
sible to select the following for cascade through the 
chain, or to make them local to the unit:
•output busses 1 through 8
•Aux sends 1 through 4
As explained above, Aux sends 5 and 6 may be used 
with the individual effect processor of each unit, pro-
viding greater exibility in effect processing in a 
larger system.
When a buss or Aux send has a check mark beside it 
(
 
4
 
), the buss or send is passed through from the unit 
to the master unit. In addition, the summed eight out-
put busses are output in parallel from all slave units 
that add their buss to the cascaded summed buss, as 
well as the master unit. 
						

							 
11 - Cascade—Using the cascade 
11–3 
NOTE 
The buss master controls on a slave unit have 
no effect on the levels of cascaded busses. 
However, the individual slave controls may be 
used to control the level of the  
STEREO OUT 
, 
the first four Aux sends and the PFL busses 
from the slave units, but this will have no 
effect on the overall summed level of the Aux 
send or stereo buss, etc.
See the diagram below for details of the buss 
summing and fader controls available for  
these cascaded busses. 
11.1.2Word sync in a cascade 
The slave units all take their clock automatically 
through the cascade connection from the master unit.
Only one sampling frequency (that of the master) is 
available in a cascade—it is not possible to mix 
44.1 kHz and 48 kHz operations in one cascade.
The master unit itself can take its clock from any 
source (except cascade, of course), including its own 
internal clock. Note that if there are digital recorders 
attached to more than one unit in the cascade, these 
should probably be set to take their clock from the 
master TM-D4000 unit in the cascade. 
11.2 Using the cascade 
The following explains the functions available in a 
cascade of TM-D4000 units: 
11.2.1Level settings 
The controls on slave units which normally control 
the output buss levels have no effect on the overall 
level of the cascaded busses output from the master 
unit.
Even though an output buss is output in parallel from 
the master and a slave unit simultaneously, the slave 
buss fader will have no effect on the level of the buss 
output from the slave. 
Likewise, although the level of the individual Aux 
sends, PFL and  
STEREO OUT 
 which are output 
from a slave unit can be set from the slave unit itself, 
the settings made on the slave unit will have no effect 
on the level output from the master. It is necessary to 
use the master buss fader to adjust these levels.
In this way, the cascade function differs from a post-
fader “sub out” that is sometimes found on analog 
consoles. 
11.2.2Option settings 
When the cascade is first set up, the master unit’s 
option settings (3.3, “Option setup”) are copied to all 
slave units.
These settings may be changed later on any of the 
units in the cascade, and the changes will be reflected 
throughout the cascade. 
11.2.3Automation settings 
Settings made in the  
AUTOMATION 
SETUP 
 screen will be copied from the master unit 
to slave units when the cascade is first set up.
These settings may be changed later on any of the 
units in the cascade, and the changes will be reflected 
throughout the cascade. 
11.2.4Monitoring 
Only the master unit’s  
MONITOR SELECT 
 keys  
[22] 
 
have any effect.
Pressing the  
MONITOR SELECT 
 keys on any of the 
slave units will have no effect, as the  
C-R 
 output 
from a slave is not the summed buss. 
11.2.5Soloing (PFL) 
When the PFL solo mode is selected, pressing the  
SOLO 
 key on any of the cascaded units will replace 
MASTER SLAVE 1 SLAVE 2
SLAVE 3
Buss is cascaded to master
Master unit’s buss 
faders control the 
buss output lev-
els from all units 
in cascade
Output busses 1–8 in cascade
MASTER SLAVE 1 SLAVE 2
SLAVE 3
Aux sends, etc are cascaded to master
Master unit’s buss 
faders control the 
summed output 
levels 
Aux 1–4, Stereo out and PFL in cascade
Individual units’ controls adjust the 
levels from these units 
						

							 
11 - Cascade—Using the cascade 
11–4  
the monitor signal on the master unit with the PFL 
signal.
The  
PFL 
 indicators on all units will flash, showing 
that a PFL signal is currently being monitored. The 
indicators will go out (and monitoring will revert to 
the monitor source selected on the master unit) when 
all PFL solos are cleared on all cascaded units. 
11.2.6Soloing (IPS) 
When the IPS solo mode is selected, soloing a chan-
nel on any console will mute all other channels on all 
other cascaded units, unless they have been solo 
defeated (see 5.4.1, “Inplace solo defeat”).
The solo defeat function is set for each unit in the 
cascade independently. 
11.2.7SOLO all clear 
When a number of channels are soloed, including 
channels on a number of different units in the cas-
caded, the soloing can be cleared from any unit in the 
chain, following the procedure described in 5.4.4, 
“To clear all soloed channels” (press and hold down 
the  
CLR 
 key of the numeric keypad and press any 
channel’s  
SOLO 
 key). 
11.2.8Snapshot library functions 
When a snapshot is recalled from any unit in the cas-
cade (see 8.1.2, “Recalling a snapshot”), all units in 
the cascade will attempt to recall snapshots with the 
same number.
If no data has been previously stored to the snapshot 
memory, a unit attempting to recall the snapshot will 
display the appropriate message.
When a snapshot is stored, using any unit in the cas-
cade (see 8.1.3, “Storing a snapshot”), the current settings will be stored on all units in the cascade. The 
existing snapshot memories in that memory location 
are automatically overwritten in all units other than 
the one from which the store operation was 
requested.
If store operation is to be confirmed on the unit from 
which the store operation was requested (i.e. the 
snapshot data will overwrite an existing library 
entry), no data will be overwritten in the other units 
until the  
ENTER 
 key is pressed to confirm the over-
write operation.
When a snapshot is named from a unit in the cascade, 
that name will be copied over the cascade, so that all 
units in the cascade will use the same name for that 
snapshot number.
Snapshot undo and redo functions (see 8.1.2, 
“Recalling a snapshot” also work for all units in the 
cascade, if performed from any unit in the cascade 
chain. 
11.2.9Talkback in the cascade 
Pressing the  
TO SLATE 
 key of any unit in the cascade 
will activate the talkback microphone of that unit, 
routing the microphone to slate, and will also dim the  
CR 
 outputs of the master unit.
However, pressing either the  
STUDIO 
 or the  
TO AUX 
1-2 
 key of a slave unit only outputs the signal of the 
slave’s talkback microphone from the slave’s outputs 
(which will almost certainly not be connected to the 
monitoring systems).
Accordingly, the master unit is effectively the only 
unit in the cascade where the  
STUDIO 
 and the  
TO 
AUX 1-2 
 keys can be used.

12 - Front panel
 
This section explains the different parts of the front 
panel of the TM-D4000.
Within this section there are also detailed explana-
tions of some system conguration, etc. procedures, 
which are linked to particular controls. In particular, 
explanations are given for the conguration keys, 
which are located to the left of the display screen.
 
12.1System controls, etc.
 
These keys and indicators provide access to functions 
that control the whole of the TM-D4000 system. 
They include controls for automation, fader-to-chan-
nel layers, library functions, conguration and gen-
eral mixer controls.
 
[1]Clock and Fs indicators
 
This section consists of indicators giving the current 
word clock status of the TM-D4000.
These 
 
Fs
 
 indicators show the sampling frequency 
currently being used by the TM-D4000, either 
 
48k
 
 or 
 
44.1k
 
.
If the sampling frequency from the selected clock 
source is out of range, or is not available, the appro-
priate 
 
CLOCK
 
 indicator will ash.
The sampling frequency may either be internally 
generated, or derived from an external source. See 
3.2,  “CLOCK setup ” for details.
These 
 
CLOCK 
 
indicators show the source of the 
word clock currently being used by the TM-D4000: 
either 
 
INT
 
 (internal), 
 
SLOT
 
 (taken from one of the 
interface cards tted in the expansion slots, 
 
D-IN
 
 
(from one of the stereo digital input ports) or 
 
WORD
 
 
(from the dedicated word clock connection).
 
[2]Automation control
 
This section consists of indicators and controls, 
mainly associated with automation procedures (auto-
mation requires an external computer system con-
nected to the TM-D4000, and is explained in the 
Automation Manual).
The automation mode keys are the 
 
WRITE
 
 key, 
 
UPDATE
 
 key, 
 
READ
 
 key and 
 
MANUAL
 
 key. Each 
one has an associated indicator.
As well as the above keys, there is also an 
 
ALL
 
 key 
(used to select all modules for a particular mode). 
   
[3]LAYER STATUS keys and indicators
 
These three keys allow the selection of the fader 
layer (for further details, see 2.4,  “Fader layers ”).
 
NOTE
 
The 
 
ST IN 1
 
, 
 
ST IN 2
 
 and 
 
STEREO OUT
 
 faders 
always control the stereo inputs and the mas-
ter stereo output buss, regardless of the cur-
rent 
 
LAYER STATUS
 
 setting, unless the option 
in the 
 
AUX
 
 screen to use faders as channel 
Aux sends in the 
 
1-16
 
 and 
 
17-32
 
 layers is 
selected (see 
 
[7]
 
). In this case, both 
 
ST IN
 
 fad-
ers will control the appropriate Aux send from 
the stereo inputs. The 
 
STEREO OUT
 
 fader will 
 
always retain its function.
 
[4]Library 
 
These keys control the storage and recall of the built-
in libraries.
The TM-D4000 stores the following internally:
All library entries may be dumped and restored using 
MIDI System Exclusive protocols.
Full details of the operation of library functions are 
given in 8,  “Library functions ”. A brief description of 
the library-related keys is given here, however.
The auto-repeating 
 
+
 
 and 
 
–
 
 keys are used to incre-
ment and decrement the snapshot library entry num-
ber shown in the top left of the display. The number 
of a snapshot library entry which has not yet been 
recalled will always be shown in inverse video. 
The 
 
STORE
 
 key stores the current console settings 
into the snapshot library entry which is shown on the 
top left of the display.
The 
 
RECALL
 
 key recalls the snapshot library entry 
shown on the top left of the display, and set the con-
sole parameters to match the values stored in the 
snapshot library entry.
The 
 
SNAPSHOT
 
 key brings up the 
 
SNAPSHOT
 
 
library screen, allowing management and naming, 
etc. of snapshot library entries.
 
Snapshots (all digital 
settings)
1 pre-set “nominal ” setting; 60 user 
settings
Effector (internal effect 
processor)
51 pre-set settings, 77 user settings
EQ (channel equalization 
settings)
20 preset settings, 80 user settings
Dynamics (channel 
compression and gating)
20 pre-set settings, 80 user settings 
						

							 
12 - Front panel—Mixing keys
 
12 –2
 
The 
 
EFFECT
 
 key brings up the 
 
EFFECTOR
 
 
library screen, allowing management and naming, 
etc. of effect processor library entries.
The 
 
EQ
 
 key brings up the 
 
EQ
 
 library screen, allow-
ing management and naming, etc. of equalization set-
ting library entries.
The 
 
DYNAMICS
 
 key brings up the 
 
DYNAMICS 
 
library screen, allowing management and naming, 
etc. of dynamics processor library entries.
 
[5]Conguration keys
 
These keys are used to make conguration changes 
and settings to the TM-D4000 system. These keys 
are all  “shiftable ”, i.e. they have two functions, as 
determined by the 
 
SHIFT
 
 key. This is explained in 
2.3.1,  “Selecting screens ”.
The 
 
GROUPING  – ST LINK
 
 key is used to assign 
fader and cut groups, and make stereo links, as 
described in 4.9,  “Fader and cut groups ” and 4.2, 
“Stereo linking ”.
The 
 
EXT.CTRL  – MIDIMC
 
 key is used to view and set 
parameters related to MIDI functions of the TM-
D4000 and external machine control.
In unshifted mode, it is used to perform control func-
tions specic to the external device selected for such 
control.
These functions are discussed in the appropriate sec-
tions (9,  “Machine Control ” and 10,  “MIDI ”).
The 
 
OPTION  – DELAY
 
 key is used to set system 
options (see 3,  “System setup ”) and (shifted) to set 
buss delays.
The 
 
DIGITAL I/O –AUTOMATION SET UP
 
 key allows 
the setting up of the word clock, digital inputs and 
outputs, and cascade settings. See 3.2,  “CLOCK 
setup ”, 3.1,  “I/O setup ” and 11,  “Cascade ” for 
details. Automation setup, as explained in the Auto-
mation manual (as well as the MTC generator opera-
tion —see 9.4.1,  “MIDI timecode generator ”) is also 
performed using this key).
 
12.2Mixing keys
 
NOTE
 
This block of keys is the “heart” of the TM-
D4000. These keys provide the methods to 
perform the usual operations carried out on 
analog consoles (EQ, aux sends, assign-
ments, etc.) as well as the specialized func-
tions which are only possible with the TM-
D4000 (internal effector, dynamic processing, 
etc.). Make sure that you familiarize yourself 
with the operation and functions of these 
keys —you will probably nd yourself using 
this section more than any other part of the 
TM-D4000. See 4, “Module operations ” for 
 
details.
 
These keys are all used to bring up screens which 
control the mixer functions of the TM-D4000 
through the display screen and the PODs. For the 
most part, these are dedicated, single-function keys, 
but in some cases, repeated presses of a key will 
bring up different, but related screens.
 
[6]FADER POSITION key
 
This key may be used when to view the position of 
the faders (see 4.10,  “Checking fader and cut sta-
tus ”).
   
[7]AUX 1 through AUX 6 keys
 
These keys all provide similar functions for the six 
Aux buss sends. The only difference between the 
Aux busses is that busses 1 and 2 can be selected to 
be pre-or post-fader, while the other busses are all 
post-fader only. See 4.5,  “Aux sends ”.
 
[8]PAN/BAL –SURROUND key
 
This key provides a way in which many channels can 
have their pan (and balance, in the case of stereo 
linked pairs) viewed and adjusted (see 4.7,  “Pan and 
balance ”). 
If a surround mode has been selected (see 6,  “Sur-
round modes ”), pressing this key brings up a screen 
allowing the viewing and adjustment of the channel ’s 
position in the surround image.
 
[9]MODULE key
 
This key allows the setting of many parameters 
affecting one input channel or a stereo pair of input 
channels. The stereo inputs and the 
 
STEREO OUT
 
 
module may also be selected for viewing and editing 
using the screens here. See 4, “Module operations ” 
for details.
 
NOTE
 
Equalization is a module-only setting —there 
 
is no global “EQ ” key. 
						

							 
12 - Front panel—Display and POD s 
 12–3 
[10] ASSIGN key 
Allows the modules to be assigned to the eight output 
busses as well as to the stereo output buss and to the 
direct outputs. See 4.4, “Channel-to-buss assign-
ments” for details. 
[11] DYNAMICS key 
This key allows the setting of the dynamics processor 
currently assigned to the selected channel(s).
See 4.6, “Dynamics processor settings” for details. 
[12] PAD/ 
F 
Sets the digital (not analog) pad and phase parame-
ters for modules. See 4.8, “Pad and phase( 
F 
)” for 
details. 
[13] EFFECT key 
This key brings up a screen which allows the editing 
of the current effector settings. 
The parameters which may be set here vary, depend-
ing on the effector currently selected, and are 
described in detail in 7, “Internal effect processor”. 
12.3 Display and POD s 
This section is described in more detail in 2, “Princi-
ples of operation”. See this section for further details 
of POD operations, etc. 
[14] Display screen 
This backlit LCD screen has a resolution of 320 x 
240 pixels.
Adjust the contrast (viewing angle) with the contrast 
control  
[17] 
. 
[15] PODs 
Each POD consists of a continuous rotary encoder 
(knob) and two switches. 
All or part of a POD may be active or inactive, 
depending on the context 
[16] ROW CURSOR keys 
Use these auto-repeating keys to move the “highlight 
box” up and down the displays in order to change the 
functions of the PODs. 
[17] Contrast control ( ) 
Adjust the viewing angle (contrast) of the display 
screen with this control. 
12.4 Module control keys 
These dedicated function keys are typically used 
with the  
MODULE 
 and  
ASSIGN 
 screens in 
order to set buss assignments, etc. 
[18] EQ key 
This key bypasses the equalization processing for the 
selected module or pair of modules.
This key can be used with any of the channel inputs, 
including the stereo inputs, and the stereo master. 
[19] DYNAMICS key 
This key is used to bypass the dynamics processor 
for the selected module or pair of modules.
This key can be used with any of the channel inputs, 
including the stereo inputs, and the stereo master. 
[20] BUSS ASSIGN keys 
These keys ( 
BUSS 1-2 (SURROUND) 
,  
BUSS 3-4 
(SUB) 
,  
BUSS 5-6 
 ,  
BUSS 7-8 
,  
STEREO 
 and  
DIRECT OUT 
) change the assignment status of the 
selected channels or pairs of channels to the appro-
priate output busses. See 4.4, “Channel-to-buss 
assignments” for details.
In surround mode, the first key ( 
SURROUND 
) 
assigns the channel to the surround busses, and the 
second key ( 
SUB 
) assigns the channel to the sub (if 
the surround type supports a separate sub channel). 
See 6, “Surround modes”.
These keys can be used with any of the channel 
inputs, including the stereo inputs.
12.5 Monitor control keys and 
meters
This section is connected with the monitoring func-
tions of the TM-D4000: the control-room monitor-
ing, studio and phones monitoring, and talkback.
The following controls, etc. are all located on the 
angled front panel of the TM-D4000.
[21] Meters
These meters show the level of the current signal 
being monitored, as selected with the monitor select 
keys.
NOTE
When working with analog equipment, the 
nominal analog signal level (either +4 dBu or  
						

							12 - Front panel—Chs 1–16, 17–32, Aux & buss send masters
12–4
–10 dBV) corresponds to a reading of –16 dB 
(relative to full-scale), which is represented 
here as –16 dBFS). This factory value may be 
changed by authorized TASCAM service per-
sonnel only to either –20 dBFS or –9 dBFS. 
Contact your TASCAM dealer for details. 
The top of the scale represents overload (over full-
scale). Unlike an analog meter reading of 0 or a 
“plus” value, which are relative to a nominal signal 
level, digital overload results in harsh distortion and 
clipping. Take care that the top 
OL meter segment 
does not light, even in the loudest parts of the 
program.
NOTE
The way in which digital equipment meters 
are calibrated varies between different manu-
facturers. While a reading of OL or OVER will 
be the same on all TASCAM equipment, there 
is no guarantee that identical readings will be 
produced on equipment from other manufac-
turers. Be aware of the possible discrepan-
cies between meter readings on different 
pieces of equipment in your setup.
[22] Monitor select keys and indicators
These keys (AUX1, AUX2, AUX3, AUX4, AUX5, 
AUX6, D-IN1, D-IN2, 2TR and STEREO) are used to 
select the signals which are routed through the moni-
toring system. These correspond to the six AUX buss 
sends, the two digital inputs, one of the two analog 2-
track mastering recorders (selected with the 
2TR 
RTN 1/2
 switch [62]) and the STEREO OUT.
The meters show the level of the selected monitor 
source(s), except for the analog 
2TR selection.
[23] PFL and IN PLACE indicators
The appropriate one of this pair of indicators shows 
the status of thr currently-selected solo mode (from 
the 
OPTION SOLO screen (see 5.4, “SOLO”). 
PFL flashes when pre-fade listen mode is selected 
and a channel is being soloed. 
IN PLACE lights 
whenever in-place soloing is selected.
[24] TO SLATE and TO AUX 1-2 keys and 
indicators
These keys allow the routing of the signal from the 
integral talkback microphone to the slate (the stereo 
output buss and the eight output busses) and the Aux 
1/2 busses. See 5.1.3, “Talkback”.
12.6 Chs 1–16, 17–32, Aux & buss 
send masters
Each mono input module has identical facilities and 
controls, regardless of whether it is being used as an 
input channel or a tape return.
Note that the majority of the operations which affect 
a channel are performed using the PODs and the dis-
play screens as described in 4, “Module operations”.
[25] REC key and indicator (modules 1–
16)
If an external machine is connected and has been 
selected for remote track arming control through the 
TM-D4000 (see the section on external machine con-
trol for details of how to achieve this), these keys and 
indicators are used to set and display the track arm-
ing and recording status of the external machine.
The 
ALL SAFE key [33] can be used to turn off the 
recording status of all tracks.
Note that the status of the keys and indicators 
changes according to the active fader layer, and is set 
up on the 
MIDI & MC SETUP 
MACHINE CTRL
 screen. 
[26] SEL key and indicator
This key and indicator are used to select the module 
for editing, etc. using the display screens. They are 
also used in grouping, etc. to select the channels 
which are part of a group (4.9, “Fader and cut 
groups”) and for the stereo linking of modules (4.2, 
“Stereo linking”).
When a module, or pair of modules linked as a stereo 
pair is selected, the appropriate 
SEL indicator(s) will 
light.
[27] SOLO key and indicator (mono 
input modules and ST IN modules)
This key and indicator are used to solo the input 
module in the appropriate mode, as selected in the 
SOLO options (5.4, “SOLO”) and shown on the 
solo indicators 
[23].
When the active fader layer is the 
MASTER layer, 
pressing the 
SOLO keys will have no effect, except 
on the 
ST IN modules (output busses and Aux sends 
cannot be soloed).
[28] CUT key and indicator
This key and indicator are used to cut the signal from 
the input channel to all output busses, the 
STEREO  
						

							12 - Front panel—Stereo input and stereo masters
 12 –5
OUT, the direct out (where appropriate) and all post-
fader Aux busses.
When the active fader layer is the MASTER layer, 
pressing the CUT keys will cut the output busses and 
Aux sends.
If Aux busses 1 and 2 have been selected as being 
pre-fader, and the CUT key of a module is pressed, 
signals will still be sent to Aux busses 1 and 2.
The CUT indicators are also used to show inplace 
solo status (all channels except the soloed channels 
will be cut).
[29]READ. WRITE, UPDATE indicators
These indicators are used to show the current status 
of the module when console automation is in 
progress, using an external computer.
[30]Layered faders
These faders are usually used to control the level of 
the signal of the module ’s current channel, Aux send 
or buss, as selected by the LAYER STATUS keys [3], 
hence the name “layered faders ”.
When the faders are  “full up ”, +10 dB of boost is 
provided. In the  “full down ” position, the signals are 
completely attenuated.
The AUX screens (4.5.2,  “Using AUX keys to set 
send levels ”) also contain an option to use the faders 
to control the level of the signal sent from the chan-
nels to the Aux buss.
The faders are motorized, but when playing back 
automated mixes from an external computer, motor-
ization may be turned off (2.4.1,  “Turning fader 
motors on and off” ).
12.7Stereo input and stereo 
masters
[31]ST IN & 2 faders
These faders are usually used to control the level of 
the signals received at the ST RTN jacks [55], as a 
stereo pair. Note that if a connection is made to the L 
jack only of one of these pairs, the channel will be a 
mono channel.
When the faders are  “full up ”, +10 dB of boost is 
provided. In the  “full down ” position, the signals are 
completely attenuated.
The AUX screens also contain an option to use these 
faders to control the level of the signal sent from the 
channels to the Aux buss (4.5.2,  “Using AUX keys to 
set send levels ”). This is the only occasion in which 
these faders do not control the levels of the stereo 
inputs, regardless of the fader layer.
Like the channel faders, these are motorized faders, 
and subject to the same restrictions and limitations as 
them.
[32]STEREO OUT fader
This fader is used to control the level of the stereo 
output buss (both channels).
When the fader is in the  “full up ” 0 position, the level 
of the stereo output is not attenuated. For example, if 
a signal is input to one channel at nominal level, and 
the channel fader is at the nominal level (0), and 
routed to the stereo outputs with the STEREO fader 
at 0, the stereo outputs will be at nominal level.
When the fader is in the  “full down ” position, the ste-
reo signal is fully attenuated.
[33]ALL SAFE key
This key is used to turn off the track arming and 
recording status for any external devices whose track 
arming function is controlled by the TM-D4000. See 
also the REC key description [25].
12.8Machine control
The machine control section allows for control of the 
external devices connected to the TM-D4000 and 
selected for control.
The exact degree of control depends on the device 
and on the settings made, and is described more fully 
in the appropriate section on Machine control.
However, a brief guide to the controls is given here, 
for reference. Where appropriate, you should read the 
documentation provided with the external unit for an 
in-depth explanation of some of the topics which are 
covered briey in this manual.
[34]TC/LOC indicators
Used to show whether the time counter [35] is cur-
rently displaying the timecode received from the 
timecode source, or is showing a location position if 
the appropriate Locate Display  
						

							12 - Front panel—Data entry section
12–6
Mode has been set (see 3.3.1, “Location display 
mode”).
[35] MDM LOCK indicators and time  counter
These three indicators (1, 2, 3) are used to show the 
running status of DTRS or ADAT units, etc. (Modu- 
lar Digital Multitrack) connected to the TM-D4000. 
The numbers refer to the units connected to the inter-
face cards fitted in slots 1, 2 and 3 respectively. 
The time counter shows the timecode from the speci- 
fied source, to frame accuracy, or the current location 
memory (as shown by the 
TC/LOC indicators [34].
The options relating to this counter (timecode source, 
etc. are set with the 
OPTION SETUP screen 
(see 3.3, “Option setup”).
[36] Punch keys and indicators
Typically used with the DTRS family of recorders, 
the 
RHSL, IN/OUT and CLEAR keys duplicate the 
REHEARSAL key,  AUTO IN/OUT  (or AUTO 
PUNCH ) and CLEAR  keys on the remote units. See 
the documentation for the remote units for details of 
how to use these keys.
[37] ALL INPUT key
Provides input monitoring for all tracks on the 
selected unit(s).
[38] AUTO MON
Provides automated switching between input and off-
tape monitoring.
[39] MACHINE SELECT
This key is used with the numeric keypad in order to 
select a machine control memory mapping (see 9.1, 
“Selecting devices for control”), etc.
[40] REPEAT 8-9 key and indicator
Used with the external units to repeat playback 
between location memories 8 and 9.
[41] MEMO, MANUAL LOCATE, EDIT,  DIRECT LOCATE, CLR keys and  
indicators and numeric keypad
Used to control the input and recall of timecode  
memory location points for location control of exter-
nal units as described in 9.3, “Location memories”.
[42] ENT key
Used to confirm entries made using the numeric key-
pad 
[41]. It may also be used in place of the ENTER  key 
[45] under certain circumstances, to confirm set-
tings made on the main display screen.
[43] Transport keys and indicators
The exact function of these transport keys and indica- 
tors depends on the device currently selected for 
external control (see 9, “Machine Control” for details 
of external device control). 
For instance, if the device selected for external con- 
trol is the internal MTC generator, the 
REC key will 
have no effect. 
Again, depending on the unit, the fast forward and  
rewind keys may or may not have an additional use 
as cue and review keys when combined with other 
transport controls, depending on the setting of the 
“cueing mode” (see 9.2.3, “Cueing Mode”).
12.9 Data entry section
[44] JOG/SHUTTLE key, indicator, dial  and wheel
The key is used to change the function of the JOG 
dial and 
SHUTTLE wheel between transport and data 
entry functions. 
When the indicator is lit, these controls act as trans- 
port controls. The exact way in which they function 
naturally depends on the device being controlled. 
When the indicator is not lit, these controls may act  
as data entry controls. The 
JOG dial is used to 
change on-screen values, and the 
SHUTTLE wheel is 
used to change the active area in certain screens (e.g. 
librarian screens).
[45] ENTER key
Used to confirm entries made using the  JOG dial, 
when used as a data entry control. 
It may also be used in place of the numeric keypad 
ENT key [42] to confirm timecode location settings, 
etc. and is also used as a “confirm” key to confirm  
settings in pop-up menus, etc. as well as turning on-
screen switches on and off, and selecting from on-
screen “radio button” lists.
[46] Cursor keys
These auto-repeating keys are used to navigate the 
cursor around the display screen, so that the parame-
ter pointed to by the cursor may be edited.

13 - Rear panel & connections 
This section describes the rear panel connectors of 
the TM-D4000.
All rear panel connections on the TM-D4000 are dig-
ital or control connections. The analog connections 
are all provided on the top of the unit, and are 
described in 12, “Front panel”. 
13.1 Analog inputs 
These features (all on the horizontal top panel of the 
TM-D4000) are provided for input channels 1 
through 8. Some of these features also apply to the 
two  
ST IN 
 channels. 
[47] MIC input (channels 1–8) 
These XLR-type connectors provide inputs suitable 
for balanced microphones, etc. to be connected to the 
TM-D4000.
They are wired as follows: 1=ground, 2=hot, 3=cold.
With the  
PAD [51] 
 off, the nominal input level for 
these connectors is –50 dBu. Using the channel’s  
TRIM 
 control, this can be adjusted between levels of 
–67 dBu and –20 dBu. 
With the  
PA D 
 on, the nominal input level is –20 dBu. 
The channel’s  
TRIM 
 control can be used to adjust the 
value between –41 dBu and +6–dBu.
The input impedance level is 2.4 k 
W  
.
Phantom power is available for these connectors. It is 
turned on and off for two blocks of input channels 
(1–4 and 5–8) using the  
PHANTOM (+48V) 
 switches  
[54] 
. 
WARNING  
Connection of microphone cables and micro-
phones: to prevent hazard or damage, ensure 
that only microphone cables and micro-
phones designed to the IEC 268-15A stan-
dard are connected.
Connexions des microphones et de leurs 
câbles: pour éviter tout endommagement, 
s’assurer de brancher uniquement des 
microphones et des câbles de microphones  
conçus selon la norme IEC 268-15A. 
[48] LINE IN (BAL) input (channels 1–8) 
These 1/4-inch balanced inputs are used to accept 
analog line-level sources.These are wired: tip=hot, ring=cold, sleeve=ground.
The nominal input level is +4 dBu, adjustable using 
the  
TRIM 
 control from between –39 dBu and +8 dBu.
No phantom power is supplied to these connectors. 
[49] INSERT connector (channels 1–8) 
These 1/4-inch TRS (tip-ring-sleeve) connectors are 
used to provide an insert loop for the eight integral 
analog inputs.
These are wired as follows: tip=send, ring=return, 
sleeve=common ground.
The nominal signal level of both the send and return 
is –2 dBu. The impedance of the send is 100   
W  
 and 
that of the return is 10 k  
W  
.
The insert send occurs post- 
TRIM 
  
[52] 
. The insert 
return is located immediately before the  
O/L 
 
indicator  
[53] 
. 
[50] LINE switch (channels 1–8) 
When this switch is pressed in, the channel’s input is 
taken from the 1/4-inch balanced  
LINE IN (BAL) 
 
inputs  
[48] 
.
When this switch is in the out position, the channel’s 
input is taken from the XLR-type balanced  
MIC 
 con-
nector  
[47] 
. 
[51] PAD switch (channels 1–8) 
When this switch is pressed in, it provides 20 dB of 
attenuation to any signals received at the  
MIC 
 con-
nectors ( 
[47] 
).
This is unconnected with the digital  
PAD 
 control 
provided as part of the  
MODULE 
 screens (see 4.8, 
“Pad and phase(  
F  
)”). 
[52] TRIM control (channels 1–8 and ST 
RTN 1 and 2) 
On the eight input channels and the two stereo 
inputs, this  
TRIM 
 control is used to adjust the input 
signal level by a range of 47 dB.
When it is turned fully counterclockwise, full trim is 
applied. Turning the knob clockwise increases the 
signal level fed to the channel’s A/D convertor. 
[53] O/L indicator (channels 1–8) 
This red LED lights when the post- 
TRIM 
, post-insert 
return signal exceeds –3 dBFS.
This LED should light only on the very loudest part 
of program material, since there is only 3 dB of head-
room remaining when it lights.
