[5] RECORD MODE switch 
Use this switch to choose between  
HR(24BIT)
 
 and  
STANDARD
 
. The  
HR(24BIT)
 
 setting records with 
24 bits of resolution. The  
STANDARD
 
 setting will 
record at 16 bits of resolution.
 
Operating Tip 
It is not possible to record a tape partly in  
HR(24BIT) 
 mode and partly in  
STANDARD 
 
mode (an error message will appear (see 
6.5.1, Warning messages). If a tape has 
been recorded in one mode, and it is required 
to re-record it in another mode, the tape must 
be rewound to the start, and the new record-
ing mode selected using this switch. The  
RECORD 
 key must be pressed and held, and 
the  
PAUSE 
 key pressed. Press and hold the  
RECORD 
 key once more, and press the  
PAUSE 
 key. The recording can now take 
place in the selected mode.
Note that it is not possible to enter input mon-
itor mode (see  
RECORD KEY [17] 
) if this  
RECORD MODE  
switch is set to one record-
ing mode and the tape currently loaded in the 
tape deck is has previously been recorded in 
another. This helps to avoid the two modes  
being mixed on one tape. 
NOTES 
When recording with the switch set to the  
HR(24BIT) 
 position, the tape moves at twice 
the normal speed. A tape which is labeled as 
a 90-minute tape will therefore provide 45 
minutes of recording time. The tape time that 
is displayed in the  
HR(24BIT) 
 mode is either 
the ABS subcode, or actual elapsed time, as 
set in 3.11, HR time display.
If a tape has been recorded in  
HR(24BIT) 
 
mode, it cannot be replayed on a DAT tape 
deck that does not support this mode.
When recording digitally from a CD or other 
material which contains fewer than 24 bits of 
resolution and this switch is set to  
HR(24BIT) 
,  
the lower “extra” bits will be unused. 
No setting is necessary to select the bit resolution for 
playback— the tape deck recognizes the recording 
mode in which the tape was recorded and adjusts 
accordingly.When the tape deck is in record ready mode, as men-
tioned above, turning the  
DATA
 
 dial  
[20]
 
 allows the 
selection of a program number other than 
 
01 
, 
meaning that this recording will start at the selected 
number, and subsequent programs will be written 
with numbers automatically incremented from this 
selected value.
 
NOTE 
Valid program numbers are from 01 to 99. If 
the above procedure is used to select a pro-
gam number at the high end of the range, and 
the automatic increment procedure takes the 
number above 99, the number will “wrap” to 
00. The number 00 can cause problems when 
searching and locating, and this should be  
remembered when setting program numbers. 
[6] Fs switch
Use this switch to select the sampling frequency 
(44.1 or 48 kHz) when making analog recordings. 
When making digital recordings, the sampling fre-
quency is automatically detected.
When playing back tapes that have already been 
recorded, this switch has no effect. The sampling fre-
quency of a recorded tape is fixed, and cannot be 
changed. 
[7] INPUT selector switch
The left (UNBAL) and center (BAL) positions of 
this switch allow the selection between the unbal-
anced RCA jacks or the balanced XLR jacks 
respectively.
The right (DIGITAL) position allows the selection of 
the digital input jacks.
[8] DIGITAL INPUT selector switch
When the INPUT switch [7] is set to the DIGITAL 
position, this switch is used to choose between the 
RCA COAXIAL and the XLR AES/EBU digital 
audio input sources.
NOTE
Despite the name of the switch setting and 
the connectors (AES/EBU), the XLR connec-
tors are capable of receiving SPDIF format 
input, and the RCA COAXIAL connectors are 
capable of receiving AES/EBU format. The 
tape deck will automatically detect the input 
format and adjust itself accordingly.

[9] ANALOG INPUT selector switch
When the INPUT switch [7] is set to ANALOG, this 
switch is used to select between UNCAL and CAL. 
UNCAL  means that the analog signal source works 
at an uncalibrated nominal level which is neither 
+4 dBu nor -10 dV, requiring the use of the input 
level controls to adjust the recording level.
The CAL position is for use with analog sources 
which are calibrated to use either the standard 
+4 dBu or the -10 dBV level as a nominal level. The 
input level controls are not used in this case. 
NOTE
If this switch is set to the CAL position, make 
sure that no parts of the program material will 
cause clipping.
[10] INPUT level controls
When recording from analog sources with the 
ANALOG INPUT switch [9] set to UNCAL, these 
controls adjust the level of the input signal to the left 
and right tape tracks.
They have no effect when the switch is set to the 
CAL position, or when recording from a digital 
audio source.
[11] PHONES control and jack
Any standard pair of stereo headphones may be 
plugged into this π-inch jack, and the level adjusted 
with the rotary control.
2.3 Tape controls
The following keys provide control of the tape trans-
port, recording modes, etc. Please read this section 
carefully if you are not sure of transport operations 
using the tape deck. 
[12] SKIP keys
These keys are used to move the tape forward or 
backward by a certain number of programs.
NOTE
A “program” on a DAT cassette starts with a 
START ID marker. The audio portion of the 
data recorded on a DAT cassette is not used 
to determine the division into tracks.Repeated presses of these keys will move the tape 
forwards or backwards by the appropriate number of 
programs (pressing the skip forward key once will 
move the tape to the beginning of the next program, 
etc.).
While the tape is locating, the display will show 
(flashing on the right) the number of programs which 
must still be passed, and (on the left) the current pro-
gram number:
In the above example, the tape is currently on pro-
gram 8, and must move two programs forward before 
the correct program (i.e. program 10) is reached.
When the start of the desired program is reached, the 
tape deck will enter the play mode if the tape was 
playing before the skip operation, otherwise it will 
enter pause mode.
[13] REW and F FWD keys
Use these keys to wind backwards or forwards fast 
through the tape.
If the tape is stopped or paused, and one of these 
keys is pressed, 
> will be shown on the 
right of the display to indicate the direction of the 
tape movement, if the margin is being displayed (see 
DISPLAY [24]).
If normal mode has been selected (3.16, Fast for-
ward mode), pressing either of these keys when the 
tape is playing will start fast forward or rewind.
If the tape is playing when one of these keys is 
pressed, and cue mode has been selected (3.16, Fast 
forward mode), the tape enters a “cue” or “review” 
mode, in which the tape is played forward or back-
ward at either three times or five times normal speed 
(if the tape has been recorded in HR(24BIT) mode) 
or twice or four times normal speed (if the tape has 
been recorded in standard mode). The cue/review 
speed can be changed by pressing the REW or F 
FWD key again, and is shown on the display as 
>>3/>>5 (cue, HR(24BIT) mode), 4 (cue, stan-
dard mode),

[15] PLAY key
Use this key to start playing when the tape is stopped 
or paused, or to start recording when the tape is in 
record pause mode (see below).
The indicator above the key will light when the tape 
is playing back. In this case, the indicator will be the 
only transport indicator lit.
The indicator may also be lit in combination with the 
PAUSE indicator, showing that the unit will enter 
playback mode almost instantly when the PLAY key 
is pressed.
If the REC indicator is lit together with the PLAY 
indicator, the unit is recording.
If the tape is locating as the result of a command to 
search for the beginning of a program (skip or pro-
gram play), and the unit was in play mode before this 
search operation started, the PLAY indicator will 
flash, showing that the unit is in “auto play” mode, 
and playback will restart when the location is 
reached.
[16] PAUSE key
Use this key to put the tape deck into pause mode, as 
explained below.
If the tape is stopped or playing, pressing the 
PAUSE key will put the tape deck into paused play 
mode (the PLAY and PAUSE indicators will both 
light).
If the tape deck is in “input monitor” mode (see [17] 
below), pressing and holding down the RECORD 
key and pressing the PAUSE key will put the tape 
deck into record ready mode (the PAUSE and 
RECORD indicators will both light).
From the record ready mode, pressing the PLAY key 
will start recording (the PLAY and RECORD indi-
cators will both light).
If the tape deck is left in pause mode for some time 
(three minutes or so), it will drop back into stop 
mode.
[17] RECORD key
Use this key for recording, as described here.
Press this key once to enter the “input monitor” 
mode. In this mode, the display gives information 
about the current status of the tape deck and the con-
nections, ensuring that clock signals, digital audio 
connections, etc. are properly made before recording 
starts.If all clock connections are in order, the display will 
show 
ANALOG in, AES/EBU or 
COAXIAL. The peak level meters will show the 
signal levels received through the selected inputs.
In the case of the latter two digital options, the sam-
pling frequency (either 
44 or 48) will be shown. If 
a digital input source is selected, and the sampling 
frequency of the received signal is outside the allow-
able range (± 0.1%) the display will show the signal 
source (
AES/EBU or COAXIAL), followed 
by a question mark. Input monitoring is possible, but 
recording is not possible.
The signal source, followed by an 
X, will be shown 
on the display if the source selected with the clock 
switch [4] is not present or has no longer 
synchronized.
From the input monitor mode, pressing and holding 
the RECORD key and pressing the PLAY key will 
start recording (the RECORD and PLAY indicators 
will both light).
From the input monitor mode, pressing and holding 
the RECORD key and pressing the PAUSE key will 
put the tape deck into record ready mode (the 
RECORD and PAUSE indicators will both light).
NOTES
If the tape deck is left in record ready mode 
for three minutes or longer, it will automati-
cally enter the input monitor mode (the head 
drum will stop spinning).
It is possible to enter input monitor mode with 
a write-protected cassette inserted, or with no 
cassette inserted. However, if a cassette pre-
viously recorded in one mode (HR(24BIT) or 
STANDARD) is inserted, and the RECORD 
MODE switch is set to the other mode, input 
monitoring is not possible. Correct this, by 
replacing the cassette with another, or as 
described in RECORD MODE SWITCH [5].
It is also possible to enter the record mode 
directly from the stop mode by pressing and 
holding the RECORD key and pressing the 
PLAY key. It is also possible to enter the 
record ready mode directly from the stop 
mode (RECORD key and PAUSE key).
[18] REC MUTE key
Use this key to record a period of silence on the tape. 
If the tape deck is recording, and this key is pressed,  
						

							2 - Parts of the tape deck
14  TASCAM DA-45HR
the RECORD indicator will flash, and all input to 
the tape will be muted. After a number of seconds 
(defined in the menu 
RecMut function—see 3.4, 
Record mute time), the tape deck will enter the 
record ready mode (the record and pause indicators 
will both be lit).
Pressing and holding the key for a few seconds will 
mute the input, and will put the tape deck into record 
ready mode as soon as the key is released.
[19] SHUTTLE wheel
Turn this wheel to move the tape backwards (coun-
terclockwise) or forwards (clockwise). Turning the 
wheel further from the center will make the tape 
move faster in the appropriate direction. 
The tape may be shuttled both forwards and back-
wards, from half-speed to eight times normal speed, 
when the tape has been recorded in HR(24BIT) 
mode, and from normal speed to twelve times normal 
speed when the tape has been recorded in standard 
mode.
When entering characters for program titles, and 
editing memory locations, etc., this control acts as a 
cursor control (counterclockwise to move the cursor 
to the left, and clockwise to move it to the right).
[20] DATA dial
This dial is used for two major functions. 
One is to change the value of data in menus and 
parameter settings.
It can also be used, however, to select an absolute 
program number at which playback should start 
(compare this with the SKIP keys, which are used to 
select a program number relative to the current 
number).
While the tape is stopped or paused, and a menu or 
edit function is not displayed, turn the data dial.
The program number following the 
> sign flashes. 
Program numbers can be from 
01 through 99, and 
turning the DATA dial past the limit will start at the 
other end of the list.
Press the PLAY key within five seconds of turning 
the DATA dial to locate to the start of the program 
and start playing.
Press the PAUSE key within five seconds of turning 
the DATA dial to locate to the start of the program 
and put the tape deck into pause mode.
NOTE
If the DATA dial is turned by mistake, either 
leave the tape deck alone for five seconds to 
cancel the operation, or press the STOP key.
2.4 Command keys
These command keys have two modes: the primary 
mode, labeled in white above the key, is the most 
common use for the key. The secondary, or shifted, 
mode is labeled in blue above the key, and is only 
operative when the SHIFT indicator [32] is lit (see 4, 
Advanced functions for details of these secondary 
modes).
[21] COUNTER MODE
Use this key to cycle through the different tape 
counter modes available:
•ABS time— the absolute time as recorded on the 
subcode of the tape. This is expressed in hours, 
minutes and seconds. If the tape is at an unrecorded 
location, the tape counter will show all dashes.
•PGM  time— the elapsed time since the last 
START ID which has been read from tape (the 
beginning of the program). If, when the display is 
in this mode, the tape is located to a point outside a 
START ID and playback restarts, the tape deck will 
be unable to determine the time since the start of 
the program and the display will show all dashes 
instead of a time value..
•REMAIN time— the time remaining on the cur-
rently-loaded cassette; to minute accuracy. Cas-
settes from different manufacturers may vary 
slightly in length, resulting in different values 
being shown for tapes which are nominally the 
same length.
• Tape Counter mode— no indication is given on the 
display of the mode, and a 4-digit number is used 
to show the tape position. This value is relative to a 
user-definable reference “zero” point (see 
MARGIN RESET [23]).

[22] CHAR
If characters have been recorded on the tape as a tape 
or program title, pressing this key will allow the tape 
deck to display these characters, scrolling across the 
display, as the START ID containing the title is 
played back. They will be replaced by successive 
title contents as they are read from tape. If characters 
are read from a START ID, the CHAR indicator will 
light in the display to indicate this. If no characters 
have been recorded on the tape, pressing this key will 
have no effect.
[23] MARGIN RESET
Pressing this key resets the margin (available head-
room) to its lowest level of 40dB. Note that in some 
display modes, there is no visible effect when this 
key is pressed.
The margin is measured in 1 dB increments between 
40 dB and 20 dB and in 0.1 dB increments between 
19.9 dB and 0 dB.
If the time display is in the 4-digit tape counter 
mode, pressing this key will reset the tape counter.
[24] DISPLAY
Regardless of the current counter mode set by [21], 
this key is used to display other information. The 
options available, which are accessed by repeated 
presses of this key, are:
•Program number and Margin mode— where the 
current program number and margin in decibels are 
displayed:
•Frames mode— where frames are displayed as 
well as hours, minutes, and seconds. The frames 
used are “digital audio” frames, i.e. there are 100 
frames in every three seconds; 33 in the first sec-
ond, 33 in the next, and 34 in the third. The pattern 
then repeats itself.
•Block Error Rate mode— the last digits of the 
display show 
E---- when out of play mode. 
When playback starts, the error rate for either the A 
or B track is displayed. The A or B track is selected 
using the MENU key while the error rate display 
mode is active.• If titles have been recorded on the tape (see 4.8, 
Character editing (titling)), CHAR is shown on 
the display, and the characters comprising the title 
are shown on the display (here, the word “TAS-
CAM” is used as the title):
[25] SKIP PLAY
When skip mode is active, SKIP PLAY is shown on 
the display. Skip mode means at that when a SKIP ID 
is encountered on tape, the tape will fast forward 
until the next START ID is encountered.
[26] AUTO ID
When AUTO ID mode is active, AUTO ID is shown 
on the display (see 4.4, ID markers (START, SKIP, 
END, CHAR and renumbering) if you are unsure 
about ID marker types). This means that when 
recording, a START ID will automatically be written 
when a “trigger level” signal is detected after a 
period of silence.
The number of the new START ID is one greater 
than the last ID successfully read from tape. How-
ever, the automatic numbering of IDs will be out of 
sequence if a START ID is added between existing 
IDs, or if an ID is written before a valid previously-
recorded START ID has been read from tape. Use the 
renumber function to restore the sequence (see 4.4, 
ID markers (START, SKIP, END, CHAR and 
renumbering).
The level which will trigger the automatic writing of 
a START ID, and the length of the silence to precede 
it may be set from the menu items (see 3.2, Auto ID 
level and 3.3, Auto ID time).
[27] ENTER
This key is used to confirm entries made in the menu 
and EDIT settings.
It is also used, when in EDIT mode (see 4, 
Advanced functions), to enter the EDIT functions).
When recording subcode (START, SKIP, END IDs 
and CHAR title information), it is used to start the 
writing of this information to tape.
[28] MENU
Repeated presses of this key (when the display is not 
in Block Error mode) cycle through the different 
options available in the menu. These options are 
explained in detail in 3, Menu functions.

[29] LOC 1
Pressing this key will locate the tape to the first mem-
ory location (set with this key in shifted mode). If the 
tape is playing when this key is pressed, the tape will 
resume playing when the location is reached, other-
wise it will stop.
When the key is pressed, the value stored in the first 
location memory will flash on the right side of the 
display (frames, program numbers and margin will 
disappear while the tape is locating, and be restored 
once location is complete).
If a pre-roll time has been set in the menu, pressing 
this key will locate to the memory location minus the 
pre-roll time.
[30] LOC 2
This key functions in exactly the same way asLOC 1 
[29] above, except that the second location memory 
is used rather than the first.
[31] SINGLE PLAY
The single play mode, when active, will play only 
one program , i.e. when the next START ID is 
encountered, playback will stop. When single play 
mode is active, the display will show SINGLE 
PLAY.
[32] SHIFT
This key is a latching key. When active, the indicator 
beside and above the key lights, and the command 
keys take on their shifted functions, as indicated by 
the blue captions above them.
See 4, Advanced functions for details of these 
shifted functions.
2.5 Rear panel
[33] DIGITAL (AES/EBU) INPUT/OUTPUT
These XLR connectors, wired in accordance with the 
AES/EBU standard, provide digital audio input and 
output facilities with the data being output in either 
AES/EBU or SPDIF format (as selected in 3.6, Dig-
ital output format). The format of data received 
(AES/EBU or SPDIF) is automatically detected.
[34] DIGITAL COAXIAL
These RCA connectors provide digital audio input 
and output facilities with the data being output in 
either AES/EBU or SPDIF format (as selected in 3.6, 
Digital output format). The bit length is set using the menu system (see 3.7, Digital out word length). 
The format of data received (AES/EBU or SPDIF) is 
automatically detected.
[35] WORD IN and THRU (AUTO TERM)
These BNC connectors provide an input for an exter-
nal word clock (selected using the CLOCK switch 
[4] set to the WORD position) at the IN connector, 
which is re-transmitted from the THRU connector. 
There is no need to provide any termination for the 
THRU connector if no connection is made to it.
[36] CONTROL I/O
This 15-pin ’D’-sub connector is used for connection 
to a suitably-equipped controller.
As well as the mode described in the table below, this 
connector can also be used as a serial connector. 
Please contact your TASCAM distributor for details 
of this facility.

[37] REMOTE IN
This 3.5 mm jack is used to connect the optional RC-
D45 remote control unit.
Do not use this jack to connect any remote control 
unit other than one designed especially for use with 
the tape deck.
[38] ~ IN 
Use this to connect the tape deck to the AC power 
supply using the supplied cable.
Make sure that the power supply voltage matches the 
voltage requirements of the tape deck as marked on 
the rear panel. If there is any doubt, consult your 
TASCAM dealer.
[39] BALANCED ANALOG inputs
These female XLR connectors provide balanced 
inputs at a nominal +4 dBu level. The wiring of these 
connectors is:1 = ground, 2 = hot, 3 = cold. The nom-
inal impedance of these connectors is greater than 
25 kΩ.
[40] UNBALANCED ANALOG inputs
These RCA connectors provide unbalanced inputs at 
a nominal –10 dBV level. The nominal impedance of 
these connectors is greater than 50 kΩ.
[41] UNBALANCED ANALOG outputs
These RCA connectors provide unbalanced outputs 
at a nominal –10 dBV level. The nominal impedance 
of these connectors is less than 700 Ω.
[42] BALANCED ANALOG outputs
These XLR connectors provide balanced outputs at a 
nominal +4 dBu level. The nominal impedance of 
these connectors is less than 27 Ω.
The trimmer beside each connector can be used to set 
the output level precisely to match the level expected 
by the equipment connected to the tape deck.
The “standard” setting (and the condition in which 
the unit is shipped from the factory) is with these 
trimmers set to maximum (fully clockwise).

3 - Menu functions
The menu facilities on the tape deck allow common 
settings to be made.
Repeated presses of MENU [28] will cycle through 
the different menu items listed here in the order pre-
sented here.
Repeated presses of the DISPLAY [24] key when 
the tape deck is in menu mode will display the differ-
ent menu items in the opposite order to the one in 
which they are presented here.
NOTE
When attempting to access the menus with 
the MENU key, the display mode should not 
be the Block Error rate display mode. In this 
display mode, pressing the MENU key 
changes between the A and B tracks.
When setting values from a menu, turn the DATA 
dial [20] to change the displayed value. The new 
value will be shown flashing on the display.
Press ENTER [27] to confirm the value.
If the DATA dial is turned, but no changes are to be 
made to the displayed value, press the MENU key 
again to return the display to the previous value.
To exit the menu mode, press either the COUNTER 
MODE [21] or the MARGIN RESET [23] key.
3.1 Drum time (head time)
Reports the time (in hours) that the head drum has 
been in use. Use this information to help schedule 
head cleaning, following the interval between clean-
ings as recommended by the cleaning cassette.
3.2 Auto ID level
When the AUTO ID function is enabled (AUTO ID 
[26]), signals which exceed this level, after a period 
of relative silence (as set in 3.3, Auto ID time) will 
automatically start the recording of a START ID at 
the point where the signal exceeds this level.
The options available are: 
-48dB, -54dB, 
-57dB and -60dB. 
The default value is 
-48dB.
3.3 Auto ID time
When the AUTO ID function is enabled (AUTO ID 
[26]), signals which exceed the level set in 3.2, 
Auto ID level will automatically start the recording 
of a START ID, if the signal has remained below the 
level for the period set in this parameter immediately 
before exceeding the trigger level.
Since the tape deck does not read track numbers, etc., 
from digital audio sources, this function should be 
used to divide CD tracks and assign new program 
numbers at the start of each track. Set the “gap time” 
as appropriate for the program material.
The times available are: 
2.0, 2.5, 3.0, 0.5, 
1.0 and 1.5 seconds.
The default value is 
2.0 seconds.
3.4 Record mute time
Sets the length of the silent period when the REC 
MUTE key [18] is pressed, the input signal to the 
tape is muted, and a period of silence is recorded. 
The values available are: 
4, 5, 6, 7, 2 and 3 
seconds.
The default value is 
4 seconds.
3.5 Reference level
Matches the input and output reference levels of ana-
log audio equipment to the digital reference standard 
in use for the recording project, meaning that when a 
nominal level (either +4 dBu or –10 dBV) analog 
signal is input, this will show as the selected refer-
ence level on the tape deck’s meters. The converse is 
true when analog signals are output from the tape 
deck (i.e. a signal at the selected reference level will 
be output at the appropriate nominal analog level).
Three options are available: 
-16dB (TASCAM), 
-18dB (European), and -20dB (SMPTE).
The default value is 
-16dB, and the  symbol on 
the display meters (between the 18 and 
14) will light 
when this value is selected.

3.6 Digital output format
Sets the format of the digital audio data output from 
both digital audio outputs (the AES/EBU XLR con-
nector and the COAXIAL RCA connector).
The options available are 
AESEBU (AES/EBU 
format) and 
Consmr (SPDIF format).
The default is 
AESEBU.
3.7 Digital out word length
When a tape has been recorded in HR(24BIT) mode, 
it may be necessary to play back the material at 16-
bit resolution. 
Note that the format of the digital audio data will 
always be output in the format as selected above (3.6, 
Digital output format) from both connectors (AES/
EBU and COAXIAL).
The options available are 
24bit and 16bit.
The default value is 
24bit.
3.8 Dither
Dithering is the technique used to improve resolution 
at low levels, with resulting loss of quantization 
noise
1. It is particularly useful when playing back 
audio recorded with higher number of bits than the 
destination is capable of receiving. 
When playing back a recording made in 24-bit HR 
mode, dithering may be used if the internal D/A con-
vertors are used. There is no effect if dithering is 
selected, and 16-bit output word length is selected.In the STANDARD mode, any dither settings made 
are applied to the signal as it is recorded.
The triangular (
Tri.) setting reduces noise more 
effectively than the rectangular (
Rect.)2, but 
both reduce the signal-to-noise ratio compared to the 
off setting, triangular more than rectangular. 
There is no rule for using dither—different circum-
stances demand different settings.
The default setting here is 
off.
3.9 Copy prohibit
Sets the level of copy protection for tapes recorded 
using this tape deck.
The menu items control the writing of the copy pro-
tection bit in the subcode of the recorded material. 
The options available are: 
Free (no copy protec-
tion is applied to the recorded material), 
1gen 
(one generation only of digital copying is possible 
from tapes produced when this setting is made), and 
Prohbt (no digital copying at all is possible). 
The second option is equivalent to the SCMS system 
implemented on consumer DAT recorders.
The default value here is 
Free.
3.10 End ID
Sets whether an END ID is automatically written 
whenever recording stops.
The two options available are: 
No WR (no END 
ID is written when recording stops) and 
AutoWR 
(an END ID is automatically written when recording 
stops). When an END ID is written, the display 
shows 
WR-EE.
When playing back and an END ID is encountered, 
EE is shown on the display, and playback stops. The 
tape then either stops or rewinds, depending on the 
setting made in 3.15, Auto rewind.
The default value is
 No WR.

learning about this, and other aspects of digital 
audio, is John Watkinson’s The Art of Digital 
Audio, pub Focal Press

3.11 HR time display
When recording or playing back in the HR(24BIT) 
mode, the tape moves at twice the normal speed. The 
tape counter can use the subcode recorded on the 
tape as its reference, meaning that the displayed time 
passes twice as fast as real time, or it can display real 
time. 
The selected display mode is used in PGM Time 
mode and REMAIN Time mode (see COUNTER 
MODE [21]). A * symbol appears at the top of the 
display when real time mode is selected.
The options available in this menu are: 
TapeTM 
(using the ABS time in the tape subcode), or 
RealTM (using real time for the tape counter).
The default value is 
TapeTM.
NOTE
This menu item only applies to tapes 
recorded in the HR mode; it has no relevance 
to tapes recorded in standard mode.
3.12 Repeat mode
This menu item controls the number of times that the 
playback will repeat when the repeat mode is set (see 
4.1, REPEAT).
The options available are: 
10TMS (the playback 
will repeat 10 times) and 
UnLimt (the playback 
will repeat indefinitely until stopped).
The default value is 
10TMS.
3.13 Pre-roll time
Sets a pre-roll time, so that the tape will locate to a 
fixed point before either of the location memories 
when the appropriate key (LOC 1 [29] or LOC 2 
[30]) is pressed. The setting made here has no effect 
on locating to the START IDs of programs using the 
SKIP keys [12] or the DATA dial [20].The values available are: 
0, 1, 2, 3, 4 and 5 
seconds.
The default value is 
0 seconds.
3.14 End tally signal
Controls the timing of the tape end tally signal trans-
mitted through the CONTROL I/O [36] port. The 
signal can either be transmitted at the end of the tape, 
or at a fixed interval before the tape end.
The values available are: 
T-End (the tally signal 
will be transmitted at the end of the tape), 
1min,  
2min and 3min (the tally signal will be trans-
mitted before the end of the tape is reached).
The default value is 
T-End.
3.15 Auto rewind
This menu item determines whether the tape will be 
automatically rewound when the end of the tape or 
an END ID is reached in play mode.
The two options available are: 
off (the tape will 
not be rewound when the end of the tape or an END 
ID is reached) and 
on (the tape will be automati-
cally rewound when the end of the tape or an END 
ID is reached).
The default value is 
off.
3.16 Fast forward mode
This menu item determines whether the F FWD and 
REW keys will act as cue and review keys, respec-
tively, if they are pressed while the tape deck is in 
play mode. The two settings are 
Normal (the 
unit will go from play mode to fast wind) and 
Cue 
(the unit will enter cue/review mode when the fast 
wind keys are pressed).
The setting made here also applies to fast wind com-
mands made through the CONTROL I/O [36] con-
nector, and using the optional RC-D45 remote 
control unit.
The default value is 
Normal.
