4.4 Buss conÞgurations
You can set the functions of the four busses con-
trolled by the 
GROUP/AUX faders (immediately to 
the left of the stereo master fader). The way in which 
these are conÞgured also affects the number as well 
as the assignment and function of the internal effect 
processors.
Depending on the conÞguration selected, these fad-
ers are used to control the output groups or the aux 
sends and the channel panpots also have different 
effects, depending on the selected conÞguration. The 
following conÞgurations are available:
In every case, channels may be routed to the stereo 
buss, and when they are routed in this way, the chan-
nel panpot controls the balance between the left and 
right channels of the stereo buss.
Aux sends may be assigned to be pre- or post-fader 
using the menu system (See ÒSetting aux send lev-
elsÓ on page 24.).There are also two user settings, where you can add 
your own settings which control the aux pre- and 
post-fader settings (explained in the Reference 
Manual).

ST+4Grp
The four group/aux busses are paired into two two-channel group buss sets: 1-2 and 3-
4. The channel panpots control the balance between the odd-numbered and even-num-
bered channels of the aux busses. The 
GROUP/AUX faders control the group mas-
ter levels. This is the default REC mode.
ST+4 Aux [1-2 ST]
The four group/aux busses are divided into one stereo aux send (1-2) and two mono 
aux sends (3, 4). The channel panpots control the balance between aux 1 and aux 2 
when channels are routed to the stereo aux bus, and have no effect on the mono aux 3 
and 4 busses. The 
GROUP/AUX faders control the aux master levels. This is the 
default MIX mode.
ST+2 Grp+2Aux
Group/aux busses 1 and 2 are assigned as two mono aux sends, and 3 and 4 are 
assigned as a dual-channel group buss. The channel panpots have no effect on the aux 
sends here, but control the balance between groups 3 and 4 when channels are 
assigned to these groups. 
GROUP/AUX faders 1 and 2 control the aux master levels 
(1 and 2) and faders 3 and 4 control group master levels 3 and 4.
ST+4 Aux [Mono]
The four group/aux busses are assigned as four individual mono aux sends. The chan-
nel panpots have no effect on the aux send levels. The 
GROUP/AUX faders control 
the aux master levels.

4.5 Where do the busses go?
As you can see from the above description, the L-R 
stereo buss is not used for recording in the REC 
modes. It goes straight out to the 
STEREO outputs 
(analog or digital) and to the 
MONITOR buss (paral-
leled to the headphone output). You should therefore 
use it as a monitor or cue buss when recording.
The behavior of the group outputs depends on the 
number of group outputs which are being used in the 
currently-selected buss function. Groups are always routed through to the TDIF-1 out-
put connector; the exact routing pattern is described 
here.
¥ If both sets of groups (1-2 and 3-4) are in use, these 
are assigned to the TDIF-1 output busses with the 
same numbers, and are also ÒdoubledÓ to 5-6 and 
7-8 respectively.
¥ If only one set of groups is in use, it is always 
group 3-4. This pair of groups is routed to all 
TDIF-1 output busses, with four ÒcopiesÓ of this 
pair going to 1-2, 3-4, 5-6, and 7-8.
These routing patterns are Þxed, and cannot be 
changed.

5 - Using the digital inputs and outputs
One of the main features of the TM-D1000 is its abil-
ity to keep sound in the digital domain throughout 
the whole of a recording project, from digital source, 
through DTRS multitrack, etc., through to the Þnal 
mix onto digital media. This results in no loss of 
quality from the start right to the end of the project. 
However, you must take care to keep the word clock 
consistent throughout the system (see ÒWord syn-
chronizationÓ on page 16 for full details).
5.1 Connecting a TDIF-1 multitrack 
recorder
The audio connections to a TASCAM DTRS 
recorder, or any recorder using a TDIF-1 digital 
audio connection, is made simply using a TDIF-1 
digital audio cable such as a PW-88D (1m) or PW-
88DL (5m). As mentioned earlier, only a genuine 
TASCAM TDIF-1 cable should be used. Although 
some kinds of computer cable may appear to be sim-
ilar, the characteristics are completely different and 
use of these cables may damage the equipment.
For word clock synchronization using a DTRS 
recorder, we suggest using the TM-D1000 as the 
slave clock unit, and setting the DTRS recorder to be 
a word clock master (see ÒWord synchronizationÓ on 
page 16) for further details concerning this. This is 
particularly important if you propose using varispeed 
on the multitrack recorder, so that the sampling fre-
quency is not an exact 44.1 kHz or 48 kHz.
Remember that if you are using a DA-38 DTRS 
recorder, this is not Þtted with a WORD SYNC out-
put. All synchronization must therefore be carried 
out through the TDIF-1 connection. With other mod-
els of DTRS recorder, it is suggested that you make a 
word clock connection to the 
WORD SYNC IN of the 
TM-D1000.
NOTE
Remember to set the DTRS recorderÕs DIGI-
TAL IN when recording using the TM-D1000.
Operating Tip
Choose your sampling frequency for the 
project carefully when connecting to other 
digital audio equipment. Both the TM-D1000 
and any TASCAM DTRS recorder can con-
nect equally well at 44.1 kHz or 48 kHz. How-
ever, CD players always work at 44. kHz, and some models of DAT recorders can only 
record analog data at 48kHz, and if you are 
using either of these as signal sources, they 
will affect the sampling frequency of all other 
equipment.
However, if the optional IF-TD1000 Digital I/O 
Board is installed, DIGITAL IN C provides fre-
quency conversion facilities. This allows you 
to, for example, transfer audio data from a CD 
at 44.1 kHz and produce a master tape incor-
porating this data at 48 kHz.
5.2 TDIF-1 word length
Since DTRS recorders are able to accept audio data 
in a variety of word lengths, the TM-D1000 is also 
able to transmit and receive data through the TDIF-1 
interface using different word lengths.
1Press and hold down the SHIFT key and press 
the 
OPTION key.
2Turn the DATA ENTRY knob until the bot-
tom line of the display shows 
System, 
and press 
ENTER.
3Turn the DATA ENTRY knob until the bot-
tom line of the display shows 
TDIF-1 
A/B Word Length
, and press 
ENTER.
If the optional IF-TD1000 Digital I/O Board has 
been Þtted, you will be able to push the data entry 
knob to choose between the TDIF-1 A and B con-
nectors.
4Turn the DATA ENTRY knob to choose 
between 
16bit , 20bit and 24bit 
word lengths. ConÞrm your selection with 
the 
ENTER key.
NOTE
You must ensure that the DTRS recorder is 
set to transmit and receive data using the 
same word length as the TM-D1000. Consult 
your DTRS recorderÕs documentation for 
details.

5.3 Connecting a 2-track recorder
The TM-D1000 provides both XLR and RCA con-
nectors for output of the stereo busses. The format in 
which data can be output is either AES/EBU or 
SPDIF. Either format may be selected for output 
from either connector, but each output can only 
transmit one format at a time (i.e. it is possible to 
output AES/EBU from output 
A XLR and SPDIF 
from output 
B RCA, but not to output AES/EBU 
from output 
A XLR and SPDIF from output A RCA).
To choose the connector from which the L-R stereo 
output busses will be transmitted:
1Press and hold down the SHIFT key, and 
press the 
OPTION key.
2Turn the DATA ENTRY knob until the bottom 
line of the display shows 
Setup:
3Press the ENTER key, and turn the DATA 
ENTRY
 knob until the display shows 
Digital Out A:B:
4Press the ENTER key, and turn the DATA  
ENTRY
 knob to choose the busses which will 
be output from the digital outputs.
The options available are as follows: 
L-R:1-2,  L-R:3-4, 1-2:3-
4, and L-R: L-R. 
To use a digital 2-track mastering recorder, select 
one of the options which outputs L-R to the digi-
tal connector to which your 2-track mastering 
recorder is connected.
5Press the EXIT key, and turn the DATA  
ENTRY
 knob clockwise until the bottom line 
of the display shows 
Digital Out 
A/B Format
.
6Press the ENTER key:
7Push the DATA ENTRY knob to change 
between the 
A and B digital outputs, and 
turn it to select between 
SPDIF and 
AES/EBU output formats for that output.
When AES/EBU output is selected, the appropri-
ate indicator immediately above the stereo master 
fader (A or B) will light.
5.4 Connecting a digital audio 
source
Because the TM-D1000 is a digital mixer, it is possi-
ble to use a digital audio source (e.g. a CD player, 
MD player, DAT recorder or effect unit, synthesizer 
or sampler with digital capabilities).
If you are using a DAT recorder as your 2-track mas-
tering recorder, this facility allows you to use the dig-
ital output of the DAT recorder for monitoring your 
mix through the TM-D1000.
This audio source may be connected through digital 
input 
A, which provides both XLR and RCA connec-
tors, and automatically recognizes the data format 
(either AES/EBU or SPDIF). It is then routed 
through to any of the input channels:
1Press and hold down the SHIFT key, and 
press the 
OPTION key.

NOTE
Because the digital input is a stereo input, you 
will probably need to select two channels to 
accept the digital audio signal.
6Press the ENTER key to conÞrm your selec-
tion.
5.5 Using digital effect returns
An increasing number of digital effect units allow 
you to send signals to them, and to input their returns 
in digital format. To select the EFFECT or AUX 
return as a digital input:
1Press and hold down the SHIFT key and press 
the 
OPTION key.
2Turn the DATA ENTRY knob until the bottom 
line of the display shows 
Setup, and press 
ENTER.
3Turn the DATA ENTRY knob until the bottom 
line of the display shows either 
Eff Rtn 
Input/Assign
 or Aux Rtn 
Input/Assign
 (depending on 
whether you are setting up the AUX or effect 
return buss), and press 
ENTER.
The default setting for the AUX return is 
Digital Input A. If this is 
already shown on the bottom line of the display, 
there is no need to press ENTER.
4Turn the DATA ENTRY knob until the bottom 
line of the display shows 
Digital In

2.
NOTE
It is possible for you to assign the digital input 
to more than one input channel (including the 
Effect and Aux return busses). All controls 
assigned to the digital input will be enabled.
5Remember to assign the input to the appro-
priate busses. Push the 
DATA ENTRY knob to 
enter the assignment screen, and assign the 
return to the 
L-R, 1-2 or 3-4 busses.
1. If the optional IF-TD1000 Digital I/O Board 
has been installed, you will also have the 
options of selecting the input from the second 
TDIF-1 port and from the second (B) digital 
input. If channels 7 and 8 are selected, the 
third (C) digital input will also be available.
Aux Rtn Input/Assign Ì

6 - Word synchronization
When you have a digital audio setup, it is most 
important that all equipment in the setup shares the 
same word clock. This is not at all related to time-
code synchronization, but refers to a digital signal at 
the sampling frequency which marks the beginning 
and the end of digital data ÒwordsÓ. If this clock is 
not present, or is distorted, the resulting signals 
passed between different pieces of equipment will 
not be synchronized, with audible noise which may 
even be high-frequency noise which will damage 
ampliÞers, speakers, etc.
The proper setup of a word clock in a digital audio 
system is therefore essential. 
We refer to devices as word clock masters or slaves, 
depending on whether the word clock is originated 
by them, or received from another device. 
NOTE
There must be one, and only one, word clock 
master in a system. 
Furthermore, each device in a digital audio setup 
must be set up to work at the same sampling fre-
quency. You cannot have a system in which a CD 
player (with a Þxed sampling frequency of 44.1 kHz) 
can be used to provide digital audio signals to a 
recorder or mixer whose sampling frequency has 
been set to 48 kHz.
The standard stereo digital signals (AES/EBU and 
SPDIF) that are marked as ÒDIGITALÓ from DAT 
recorders, CD players, etc. carry their own clocks as 
part of the signal. Most ÒdomesticÓ CD players and 
DAT recorders will expect to be the word clock mas-
ter when playing back, and (in the case of a DAT 
recorder) when recording, will become a word clock 
slave.
Professional equipment (DAT recorders, CD players, 
digital multitrack and hard disk recorders, and digital 
mixers such as the TM-D1000) can usually be con-
Þgured to act as either a word clock master or slave.
6.1 Setting up the TM-D1000 as a 
word clock master
The TM-D1000 can be conÞgured as a word clock 
master at either 44.1 kHz or 48 kHz.
NOTEIf the TM-D1000 is conÞgured as a word clock 
master, you cannot use any varispeed facili-
ties on any digitally connected devices (multi-
track systems, CD players or DAT recorders).
1Press and hold down the SHIFT key and press 
the 
OPTION key.
2Turn the DATA ENTRY knob until the bot-
tom line of the display shows 
System and 
press 
ENTER.
3Turn the DATA ENTRY knob until the bot-
tom line of the display shows 
Master 
Clock Select
, and press ENTER:
4Use the data entry knob to choose either 48 
kHz or 44.1 kHz as the internal clock.
5Make sure that any other devices which can 
accept external word clocks are set to do so.
NOTE
The TDIF-1 standard allows any DTRS or 
other TDIF-1-equipped device to take its clock 
through the TDIF-1 connector. However, we 
recommend that if you are using the TMD-
1000 as a word clock master, that you con-
nect the TM-D1000Õs 
WORD SYNC OUT to the 
WORD SYNC IN of the DTRS recorder (not 
DA-38 models), and use the CLOCK key of 
the DTRS recorder to select WORD as the 
clock source.
6.2 Setting up the TM-D1000 as a 
word clock slave
The TM-D1000 can accept a word clock from any of 
the digital audio inputs (including the TDIF-1 input, 
or inputs, if the optional expansion board is Þtted) or 
the 
WORD SYNC IN connector. 
1Press and hold down the SHIFT key and press 
the 
OPTION key.

3Turn the DATA ENTRY knob until the bot-
tom line of the display shows 
Master 
Clock Select
, and press ENTER:
4Use the DATA ENTRY knob to choose the 
word clock source for the TM-D1000.
The external word clock source may be the 
TDIF-1 A source, the Digital 
In A, or the Word Sync In con-
nection. If the optional expansion board is Þtted, 
the additional digital inputs, except for digital 
input C, which contains a sampling frequency 
convertor, may also be selected as word clock 
sources.
Remember that all other digital audio devices in 
the system must also be set as slaves (except for 
the word clock master) and must be connected so 
that the word clock is transmitted to them.
NOTE
When using the TM-D1000 with a DTRS or 
other recorder in varispeed mode, the TM-
D1000 must be conÞgured as a word clock 
slave. We suggest that you use the Word 
Sync In as the clock source when using the 
TM-D1000 as a word clock slave with DTRS 
recorders, except with DA-38 recorders.
When using a DA-38 recorder in varispeed 
mode, the only available word clock source for 
the TM-D1000 is the 
TDIF-1 A source. 
This is because the DA-38 must act as a word 
clock master in varispeed mode, and has no 
word clock output jack.
A complete discussion of digital audio is outside the 
scope of this guide. You should consult one of the 
many excellent books on the subject if you are in any 
doubt.

7 - Channel operations
This covers most common channel operations 
(equalization, routing, etc.), as well as the channel 
dynamic processors. It does not cover aux sends and 
effects, which are described in ÒEffectsÓ on page 23.
Fader operations are similar to those on any analog 
console. The ÒnominalÓ level is marked by a 0 on the 
fader scale.
The panpot controls are also similar to those of an 
analog console.
7.1 Equalization
One of the most common tasks in recording is to 
adjust the equalization. To do this on the TM-D1000:
1Press the PARAM SEL key until the EQ indi-
cator lights green:
If you see the CH SEL! message, the TM-
D1000 is reminding you to select a channel to 
which you will apply the equalization settings.
2Press the CH SEL key of the channel to which 
you want to apply equalization.
3Press the EQ key beside the CH ASSIGN keys 
(above channel 6) so that it is lit, to enable 
equalization on the selected channel.
Operating Tip
It is very important to remember this step. If 
the 
EQ indicator is not lit when you are editing 
the EQ settings, there will be no audible 
effect. You can also use this key as an ÒA-BÓ 
selector to examine the effects of your equal-
ization settings.
4Adjust the equalization gain and frequency 
in the three bands using the data editing 
knobs. 
Use the DATA ENTRY knob to view and set the 
second set of parameters (notice that the MID 
gain and frequency are always visible and con-
trolled by the center two data editing knobs). 
Each frequency band has the same frequency 
range (from 41 Hz to 16.0 kHz) and the same cut 
and boost (±15 dB in 0.5dB steps).However, the LOW and HI bands are shelving 
Þlters, which work in a slightly different way to 
the peak/dip Þlter of the MID band.
7.2 Routing channels to busses
As explained earlier, there are four busses on the 
TM-D1000 whose function may be either aux or 
group busses, as explained in ÒBuss conÞgurationsÓ 
on page 11. To assign input channels to these busses 
when their function is set as group busses:
1Press the CH SEL key of the channel you wish 
to assign to a buss.
2Press any combination of the 1-2, 3-4 or L-R 
CH ASSIGN
 keys (above input channels 3 
through 5). When a 
CH ASSIGN key is lit, the 
channel whose 
CH SEL key is lit will be 
routed through that pair of busses.
WARNING
Do not route a tape return to the buss which 
feeds that trackÕs input. For instance, if you 
have selected the buss function with four out-
put groups, tape tracks 1 and 2 will be fed by 
busses 1 and 2 and be returned to channels 9 
and 10. If channels 9 and 10 are routed to 
busses 1 and 2, an undesirable loop will 
occur, resulting in feedback, and possible 
damage to your equipment.
If none of the four busses is set as a group bus, or if 
only one pair of group busses is set, either or both of 
the 
1-2 and 3-4 keys will be disabled. The L-R key is 
always enabled.
To check the routing of input channels, simply press 
the 
CH SEL key of the channel you wish to check, 
and observe the 
CH ASSIGN keys.
Operating Tip
Remember that there is no dedicated monitor 
or cue buss on the TM-D1000. If you want to 
monitor an input channel or a tape track in 
recording mode, you should assign it to the L-
R buss, as explained earlier.

7.3 Using the DIRECT OUTs
The input channels can be sent to the TDIF-1 outputs 
on a one-to-one basis instead of being routed through 
the group busses. Use the 
DIRECT OUT key instead 
of the 
CH ASSIGN keys.
NOTE
The direct out facility is obviously useful only 
in the REC mode; in the MIX mode, there is 
little point in sending input channels to the 
TDIF-1 outputs.
Although you can assign an input channel to 
the group busses and to the direct outputs at 
the same time, this is not useful in many 
cases. We therefore suggest that you use 
either the direct out or the group busses, but 
not both.
The DIRECT OUT pick-off point can be set to be 
either pre-or post-fader.
1Press and hold down the SHIFT key, and 
press the 
OPTION key.
2Turn the DATA ENTRY knob until the bottom 
line of the display shows 
Setup, and press 
ENTER.
3Turn the DATA ENTRY knob until the bottom 
line of the display shows 
Direct out

, and press ENTER:
4Use the DATA ENTRY knob to choose between 
Post Input Fader (post-fader 
output) and 
Pre EQ (pre-fader and pre-
EQ), and use 
ENTER to conÞrm your selec-
tion.
7.4 Assigning channel dynamics
The default effect pattern when recording is to assign 
four mono dynamic processors to input channels. To 
use these processors:
1Press and hold down the SHIFT key, and 
press the 
OPTION key. 
2Turn the DATA ENTRY knob until the bottom 
line of the display shows 
Effect.
3Press ENTER, and turn the DATA ENTRY 
knob until the bottom line shows 
Ch 
Dynamics Insert
.
4Press ENTER:
Each number on the display represents one of the 
dynamic processors assigned to a channel. The 
channel number corresponds to the numbers 
printed under the display. In the above example, 
dynamic processors 1 through 4 are assigned to 
channels 1 through 4.
5Turn the DATA ENTRY knob to move the cur-
sor, and push it to toggle the dynamic proces-
sor assignment on or off for the channel 
whose number is under the cursor.
6Turn the DATA ENTRY knob to select an 
available dynamic processor.
This does not toggle the processor on or offÑjust 
the assignment of the processor to the channel.
7To set the dynamic processor parameters, 
press the 
CH SEL key for the channel whose 
processor you want to edit.
8Press the PARAM SEL key until the EFFECT/
DYNAMICS
 indicator lights green.
9Use the DATA ENTRY knob to switch the dis-
play of the dynamic processor parameters, 
and use the data editing knobs to adjust the

7.5 External insert points
The TM-D1000 is capable of using external inserts 
on channels 1 through 4, as well as using its internal 
dynamic processors. Use standard ÔYÕ cables such as 
TASCAM PW-4Y or PW-2Y cables to connect an 
external processor.
The tip of the p-inch TRS jack plug is the ÒsendÓ of 
the TM-D1000 to the external processor, and the ring 
is the ÒreturnÓ. The sleeve is used as a common 
ground.
7.6 Linking channels for 
simultaneous parameter 
adjustment
You may Þnd it useful to link adjacent channels so 
that changes made to the parameters on one channel 
also affect the adjacent channel.
Odd-numbered channels may be linked in this way 
with the even-numbered channel immediately fol-
lowing (e.g. channel 3 may be linked with channel 4, 
but not with channel 2 or with channel 5).Channels may be linked if either of them is assigned 
to use an in-line dynamic effects processor (see 
ÒAssigning channel dynamicsÓ on page 19). In this 
instance, they will share a linked two-channel 
dynamic effect processor (changes made to one 
channelÕs processor will affect the other channelsÕs 
processor).
1Press and hold down the CH SEL key of one 
of the channels to be linked.
2Press the CH SEL key of the other channel.
To un-link the channels, repeat the process.
When you link channels, the following parameters 
will be applied to both channels simultaneously:
¥ Fader levels (moving one fader will have the effect 
of moving both faders simultaneously, even though 
the second fader does not physically move).
¥ Channel assignment (see ÒRouting channels to bus-
sesÓ on page 18).
¥ Equalization parameters and the EQ switch (see 
ÒChannel operationsÓ on page 18)
¥ Channel muting
¥ Aux send levels (see ÒSetting aux send levelsÓ on 
page 24)
