(MIC/LINE or INPUT) is selected, they act as overload 
indicators when the input level exceeds the level set 
in the 
LEVEL field (OVER, 0, –2, –4, –6, –8, –10, –12,
–18, –30 or –42 (dB).
This status can be set for either the 
MIC/LINE inputs 1 
through 16 or for the 
INPUT associated with the mod-
ule, using the appropriate radio buttons.
Set the level for the overload lighting by moving to 
the value, pressing the 
ENTER key, turning the dial to 
set the value and pressing 
ENTER to confirm the 
value.
Otherwise, if the 
AUTOMATION option is selected, 
these indicators show the current automation status 
of the channels, as explained in the automation 
manual.
FADER SENSITIVITY This parameter allows you 
to specify the sensitivity of the faders, as used in the 
automation process.
The DM-24 touch sensing capabilities are dependent 
on the ambient humidity and environment. Depend-
ing on these factors, it may sometimes happen that 
faders which have been touched are not recognized 
as having been touched, or the faders are recognized 
as having been touched when they have not actually 
been touched.The value of the sensitivity is set by default to 4.0k, 
but you may wish to set it to any of the following val-
ues: 
1.0k, 1.5k, 2.0k, 2.5k, 3.0k, 3.5k, 4.0k (Hz). High 
values mean higher touch sensitivity.
While the 
FADER SENSITIVITY on-screen button is 
switched 
ON and this screen is visible, touching any 
of the faders with your fingers will illuminate the 
STATUS/OL indicator for as long as the fader is 
touched. This provides a very useful check for the 
sensitivity of the faders.
METER CALIBRATION Move the cursor to the 
START button and press ENTER to start the process of 
calibrating the DM-24 meters.
WARNING
You must turn down the headphone and control room 
monitor levels before starting this check, to avoid any 
possible damage to your ears and to the control room 
monitoring system.
Press the ENTER key (or cancel the process using a 
cursor key). After the meter calibration process has 
finished (about 3 seconds), the message 
METER 
calibration finished
 appears as a popup message. You 
can then restore the control room and headphone lev-
els.
PREFERENCES
The following general working preference settings 
are available from this screen: 
Fader Auto MODULE Select When enabled 
and a 
MODULE or DYNAMICS screen is shown, this 
option allows a module to be selected whenever its 
fader is touched, in addition to the usual method of 
pressing the 
SEL key. In other screens, when this 
option is enabled, the module shown at the top left of 
the screen changes when its fader is touched.
Select MODULE Return When checked, this 
option allows the 
MODULE screen of the appropriate 
module to appear if the 
SEL key of the module is 
pressed and held for about two seconds.
ST Link by SEL key When checked, this option 
allows the stereo linking of two adjacent modules 
(provided the left module of the pair is odd-num-
bered) by pressing and holding the 
SEL key of one 
module and pressing the 
SEL key of the other.
Balance Level CENTER: 0dB When two chan-
nels are linked together as a stereo pair, the pan con-
trols change to a balance control, as mentioned 
earlier. In the center position, the level may either be 
set to 0 dB (checked) or a 3 dB cut (unchecked).
SEL Key Follows Fader Layer Status allows 
the setup of the automatic linking of the selected 
channel to the selected meter layer.
When this option is selected, if a channel is selected, 
the fader layer is changed, and then the fader layer is 
changed back again, the originally-selected channel 
is automatically selected.

For example, if this option is active, and SEL 2 key is 
lit with fader layer 1-16 active, fader layer 17-32 is 
then selected, 
SEL key 3 (channel 19) is selected, and 
then fader layer 1-16 is then re-selected, 
SEL key 2 
will be active.
If the option is not active, any 
SEL key which is lit 
remains lit when the fader layer is changed. For 
example, if this option is not selected, and 
SEL key 2 
is lit with fader layer 1-16 active, and fader layer 
17-24 is then selected, 
SEL key 2 will still be lit (that 
is, channel 18).
Meter Follows SEL key When this option is 
checked, the meter layer automatically changes when 
the appropriate 
SEL key is pressed (see “Meters and 
faders” on page 77). The modes are as follows:
Automation fader OFF When this option is 
active (checked), in automation mode, when the 
automated mix is being read (played back), the faders 
do not move.
Cursor follows EQ Band Key When the 
option is enabled and modules are being edited, and 
any of the EQ band keys (
HI, HI MID, LOW MID or 
LOW) is pressed, the box cursor surrounding the 
active on-screen controls will move to highlight the 
active band.
FLASH Info. This on-screen button allows you to 
see how many times the flash memory used for stor-
ing library entries, etc. has been used (written to). 
Moving the cursor to this on-screen button and press-
ing 
ENTER brings up a pop-up panel showing the 
number of times that the flash memory locations 
have been used. Pressing 
ENTER again allows you to 
view the automation memory area usage. Dismiss 
this pop-up by pressing 
ENTER once more. 
If any flash memory location has been written to too 
many times in the life of the unit, a popup message 
will automatically appear to alert you of this fact. 
You should then contact your TASCAM dealer for 
service.
Version Info. For service, etc. it is useful to know 
the software version numbers of the different compo-
nents. Moving the cursor to this on-screen button and 
pressing 
ENTER brings up a pop-up panel with the 
software version numbers of the different compo-
nents (including the internal effector units). Press 
ENTER to dismiss this panel.
Battery Check This is a “read-only” display. It 
shows the current voltage and the status of the 
DM-24’s internal battery.
If the battery voltage falls below a certain level, or is 
reported as being above a certain level, this display 
blinks, and the screen shows 
Can’t Save System Data, 
together with the out-of-range voltage.
Consult your TASCAM distributor if you see this 
message.
SOLO
The solo modes on the DM-24 can be set up in a 
number of different ways using this screen:MODE SELECT Either Mix Solo or Exclusive Solo 
can be selected here. The 
Mix Solo mode allows a 
number of channels (that is, all whose 
MUTE keys 
are lit in solo mode) to have their outputs added 
together to the solo mix. The 
Exclusive Solo mode only 
allows one channel (the one whose 
MUTE key was 
pressed last) to be soloed at one time.
SOLO LINK This option allows the fader and mute 
groups to be used with the solo function. This is 
explained more fully in the solo part of the section 
describing monitoring (see “SOLO LINK” on 
page 75). Briefly, if one of the group options (
MUTE 
GROUP
 or FADER GROUP) is enabled, selecting a group 
master module solos or unsolos the whole of the 
group. If a group slave module is selected, the solo 
status of only that slave module is affected.

 TASCAM DM-24 Reference Manual 23
SOLO TYPE There are three options that may be 
selected here: 
PFL (pre-fader listen), AFL (after- or 
post-fader listen) and 
INPLACE SOLO. Again, these are 
explained in more detail in the solo section, but 
briefly; the 
PFL option provides a way of listening to 
the signal before it is sent through the panpot and 
fader. The stereo outputs are unaffected (soloing is 
only done through the 
CR and STUDIO monitor out-
puts) An AFL selection will output the post-fader 
signal from the selected channels through the moni-
toring system. By contrast, soloing a channel in 
Inplace Solo mode monitors the soloed signal(s) via 
the stereo outputs while all the other signals are cut 
from the stereo outputs.
INPLACE SOLO DEFEAT This option is a defeat 
option to prevent channels selected in this way from 
being muted when other channels are soloed. It can 
be used with a pair of effect returns, for instance, so 
that these effect returns will always be added in the 
inplace mix, together with those other channels 
selected for inplace soloing. Inplace soloing will out-
put the soloed channel(s) from the stereo outputs, and 
cut all other channels. Use the cursor keys (or chan-
nel 
SEL key) to highlight a channel, and the ENTER 
key to change the status of the INPLACE SOLO DEFEAT 
setting.
Alternatively, use the 
SEL keys of the modules for 
direct selection and de-selection of the channels (use 
ENTER to make the setting).
SYNC/TC
The following settings affect the timecode and syn-
chronization settings (as can be selected for display 
on the top right of the screen, used for automation 
purposes as well as for location, etc.):
The screen is split into two parts: the top part allows 
the selection of a timecode source for display. This 
displayed timecode may be the source used for auto-
mation synchronization (
Sync Source) or another 
source of timecode (
OTHERS). 
If 
Sync Source is selected, the source selected in the 
lower part of the screen to determine the automation 
synchronization source is displayed.
The following options are available for the display of 
incoming timecode:
DTRS Remote Timecode This is the timecode 
embedded in the REMOTE/SYNC output from a 
DTRS unit. The actual format and the relationship of 
this to the ABS time on the DTRS unit depends on 
the setup of the DTRS unit. If the ABS time is used 
as the timing source on the DTRS unit, 
ABS is shown at the top right of the DM-24 display (above the time-
code value). If timecode is selected as the timing 
source on the DTRS unit, 
TC is shown on the top right 
of the display.
NOTE
A DTRS unit connected to the DM-24 through a card 
inserted in slot 1 or 2 cannot be used as a timecode dis-
play source in this way.
RS-422 IN Timecode This refers to any timecode 
received through the RS-422. If this option is 
selected, 
TC is shown on the top right of the DM-24 
display.
TRA Target link This refers to the timecode from 
the currently selected transport target (as set up in the 
MIDI/MC settings
Either 
TC or DTRS is shown on the top right of the 
screen if the transport target is a DTRS unit (as 
explained above), 
ABS if an ADAT is selected, MTC if 
the transport target is a closed MMC loop, and 
INT if 
the internal generator is selected as the transport tar-
get.
If the transport target is a MMC closed loop device, 
this (
MMC Closed) is highlighted on screen.
Automation synchronization source 
Choose from the following options to select the auto-
mation synchronization timecode source:
TC IN This refers to the analog linear timecode sig-
nal received at the 
TC IN jack. If this option is 
selected, 
TC is shown on the top right of the DM-24 
display. 
						

							3 – System-wide options—DIGITAL screens
24 TASCAM DM-24 Reference Manual
MIDI IN MTC This refers to any MIDI Timecode 
received at the 
MIDI IN jack. If this option is selected, 
MTC is shown on the top right of the DM-24 display.
INT. This refers to the DM-24’s own internal (MIDI 
Timecode) generator. 
NOTE
The internal timecode generator is not functional in this 
release of the DM-24 software. It will be implemented 
in a future release, and appropriate documentation 
concerning its use will be provided at that time.
If the internal generator is chosen, the frame type can 
be selected from the following list: 
30DF (30 fps 
drop-frame), 
30NDF (30 fps non-drop), 29.97DF (29.97 
fps drop-frame), 
29.97NDF (29.97 fps non-drop), 25 
(25 fps) and 
24 (24fps). If this option is selected, INT 
is shown on the top right of the DM-24 display.
If the internal frame type is changed, then an auto-
matic calculation is performed to convert the old 
frame type as accurately as possible to the new frame 
rate. For instance, if the frame type is 24 fps and the current frame position is set to 12 (that is, halfway 
through a second), if the frame type is changed to 30 
fps the frame position will be set to 15 (again, half-
way through a second).
NOTE
When external timecode sources are used, the frame 
type is automatically recognized.
INT. START TIME If the internal generator is 
selected as the timecode source, then the PODs are 
used to set the generator start time. Move the cursor 
so that the time is surrounded by an on-screen box, 
and then use the four PODs to set the hours, minutes, 
seconds and frames of the generator start time.
FLY WHEEL (frames) If an external timecode 
source is selected, then it is possible to compensate 
for loss of incoming signal, allowing the DM-24 to 
“flywheel” for a set number of frames before it 
reports the loss of incoming timecode. The values 
available here are 8, 16 and 32 frames (the length of a 
frame depends on the frame type being received).
DIGITAL screens
The DIGITAL screens contain a number of different 
parameters affecting the digital audio operation of 
the DM-24.
There are three screens: the 
CLOCK screen, where the 
digital clock source is selected, the 
FORMAT screen, 
which provides facilities for controlling the format of 
digital data transmitted from and received by the DM-24, and the 
SLOT screen, to control any optional 
cards fitted in the slots.
NOTE
There should be one, and only one, word clock source in 
a digital audio setup. Multiple word clocks in a setup 
may result in noise which can damage monitoring 
equipment (speakers and amplifiers).
CLOCK settings
This screen allows the viewing and selection of digi-
tal audio clocks from devices connected to the 
DM-24.Use the cursor keys or dial to move around the 
screen, and the 
ENTER key to make selections.
Depending on the current assignments, the screen 
may change a little from that shown here. For exam-
ple, if ADAT has not been selected as a return source, 
then it will not be shown in the appropriate position. 
If slot cards are not fitted, they will not appear on this 
screen, but if they are fitted, the 
SLOT fields to the left 
of the screen are filled, and show the slot cards cur-
rently fitted.
The condition of a master clock status is shown using 
symbols.
If the right clock is not available, or if the clock is out 
of the permissible limits, an appropriate symbol 
(cross or question mark) is shown.

 TASCAM DM-24 Reference Manual 25
A popup appears with an unlocked indication and an 
error message. If this happens, correct the clock 
source, and press the 
ENTER key to dismiss the 
popup.
When a clock source is selected, the clock indicators 
to the left of the console change to show the current 
clock frequency and the 
EXT CLOCK indicator lights 
if an external clock has been selected as the clock 
source.
High sampling frequency To select high sam-
pling frequency mode, select 
Hi-Sampling, and press 
ENTER.
When the DM-24 changes to high sampling fre-
quency, a popup message is shown on screen, telling 
you to turn off the DM-24 and turn it on again, to 
enter high sampling frequency mode.
NOTE
Remember to turn down the monitor value, etc. to 
avoid “thumps” which may damage equipment when 
turning the DM-24 on and off.
The clock source screen changes in the case of high 
sampling frequency being selected.
NOTE
Many other display screens will change if high sampling 
frequency is selected. These differences are described in 
a separate chapter (“High sampling frequency” on 
page 112).
Fs Status This shows the current sampling fre-
quency status (base frequency, deviation from the 
nominal value, and the locked/unlocked status).
Select the appropriate clock source. In the case of the 
internal clocks, the frequency may be chosen as 
either 44.1 kHz or 48 kHz. In most other cases, the 
frequency is pre-determined.
There are one or two other points to be borne in mind 
when making these settings.
D-IN MANUAL SETUP A manual selection may 
be made in the case of one of the digital inputs (
D-IN) 
being selected as a clock source with sampling fre-
quency conversion. Select the appropriate destination 
frequency here.
Whether the RCA or XLR connector is used as the 
clock source is selected in the 
I/O screens (“Digital 
inputs” on page 39), not here.
WORD SYNC IN Since the frequency information 
of any signal received at the 
WORD SYNC IN con-
nector is not used by the DM-24, if this source is to 
be selected as the word sync source for the DM-24, 
the sampling frequency must be explicitly selected.
TDIF interfaces In the case of the TDIF-1 inter-
faces card), the device attached to the card source is 
shown as either a 
DA-88 (DA-88 DTRS recorder) or 
OTHER (another type of recorder connected through 
the TDIF-1 interface). If the indicator shows DA88, 
then I/O data is truncated to 16 bits, otherwise I/O is 
carried out at 24 bits.
ADAT In the case of an ADAT “lightpipe” interface 
card, the 
INT setting, allowing the ADAT to act as the 
clock master, is always selected.
AES3 In the case of an AES/EBU interface card, 
there are four different sources (the four AES/EBU 
inputs
1) which may be selected as the word clock 
source for the DM-24.
CASCADE MASTER If the DM-24 has been set 
up as a cascade slave (using the 
DIGITAL SLOT 
screen), then this cascade master option is automati-
cally selected, and this setting cannot be changed (the 
master is free, of course, to accept its clock from any-
where).
Word phase The phase of the word sync signal 
can be inverted independently for input and output 
relative to normal. Use the phase correction facilities 
to match word clocks from different equipment.
Checking the clock sources
To give details of all possible sources, move the cur-
sor to the on-screen 
CHECK button, and press ENTER.
A popup message appears. Use the 
ENTER key to 
continue with the check (cancel using any of the cur-
sor keys).The DM-24 mutes, and a panel appears with details 
of all possible clock sources. Press 
ENTER once 
again to dismiss this panel.
1. This changes to two inputs when high fre-
quency sampling is selected.

26 TASCAM DM-24 Reference Manual
Out of range clock signals
When setting the clock, the sampling frequency 
received can be ±6% of the stated nominal value. 
When in use, the frequency can be ±7% of the stated 
value. This allows a digital device which has a 
varispeed feature to be used as the word clock source 
for the DM-24.
If the selected clock source goes out of range, the 
DM-24 mutes, the currently-selected clock indicator 
flashes, and a message appears on the display.The DM-24 reports the out-of-range clock frequency 
at a range of ±9.9% relative to the stated frequency, 
but mutes at 7.0% or over.
Press the 
ENTER key to dismiss the popup message, 
change to the 
CLOCK screen, and correct the error 
condition (by selecting another clock source, or by 
re-selecting the clock if it has come back into range).
The FORMAT screen
This screen allows you to see and work with the digi-
tal audio inputs and outputs connected to the DM-24.
The first part of this screen affects the digital inputs. 
Note that the I/O screen is used to determine whether 
the XLR connector or RCA pin jack is used for each 
of these inputs.
Type of DIGITAL IN connection Typically, 
these connectors will be used for base frequency dig-
ital audio (44.1 k or 48 k). This is shown as 
NORMAL 
on the display. However, if the DM-24 is in high 
sampling frequency mode, these inputs may be used 
for high sampling frequency inputs. There are two 
ways in which they can be used for high sampling 
frequency; 
DUAL-LINE (where one AES/EBU cable is 
used to transmit one channel of high sampling fre-
quency audio, hence two lines are needed for a stereo 
pair) and 
HIGH-SPEED where the audio is transmitted 
at twice the usual speed, where one AES/EBU cable 
is used to transmit a pair of high sampling frequency 
signals at high speed.
Use the cursor, dial and 
ENTER key to set this value. 
If the DM-24 is set to an incompatible sampling fre-
quency, a popup message appears.
Other digital input parameters At normal 
base sampling frequencies, the DM-24 is capable of 
performing sampling frequency conversion on the 
incoming data. This can be turned on or off individu-
ally using the on-screen 
Fs CONVERT buttons.
The 
MUTE DEFEAT checkbox allows the DM-24 to 
ignore a status bit in some implementations of digital 
audio, which are otherwise satisfactory. If this is 
unchecked, when this audio is received, the input 
may be muted and the following messages may be 
displayed on screen: 
Not Audio data Digital In1 (byte 0, 
bit 1=1 of the channel status) or 
Source Fs unlocked 
(byte 0, bit5=1).
Details of the digital audio data can be obtained from 
a popup produced by pressing the 
DETAIL button. 
Such information includes the format, type, emphasis 
status, etc.
Digital output The assignments for the two digi-
tal outputs are made using the I/O screen. The format 
can be changed between AES/EBU and SPDIF (the 
SPDIF option is meaningful at base sampling frequen-
cies only) and details of the data can be obtained 
from a popup produced by pressing the 
DETAIL but-
ton. Such information includes the format, contents, 
emphasis status, word length, etc.
Multi I/O settings These assignments are made 
in the I/O screen, and cannot be changed. However, 
the word length for each of the TDIF groups can be 
set (either 
16bit, 20bit or 24bit) and the details can be 
viewed (
DETAIL button). These details include TX/RX 
mode, sampling frequency, word length and empha-
sis status, etc.
Stereo out setup This allows the choice of the 
word length output from the stereo out as being 
either 24-bit data, 20-bit with noise shaping, or 16-bit 
with noise shaping.

Analog module inputs
These inputs typically feed the first sixteen input 
channels, but may be assigned in other ways as 
explained in “Setting up the I/O” on page 36.
1INSERT These TRS 1/4” connectors are used 
to provide a post-
TRIM insert (send at –2 dBu), and 
the return (–2 dBu) occurring just pre-AD convertor.
2LINE IN (BAL) These balanced 1/4” jacks 
accept analog inputs at a nominal +4 dBu input level, 
adjustable with the 
TRIM controls.
3MIC These XLR connectors accept analog 
inputs for balanced microphones. Phantom power is 
available (switchable in groups of 4 inputs).
The input level is adjustable with the 
TRIM controls.
NOTE
There is no switch to allow a choice between the MIC 
and the 
LINE inputs. Accordingly, connections should 
not be made to both inputs of a channel simulta-
neously.
WARNING
4TRIM These controls allow the input levels 
from the 
MIC and LINE inputs to be adjusted over a 
range of 56 dB.
Turning these controls clockwise increases the level 
of the signal fed to the channel AD convertors.
5PHANTOM (+48V) These switches allow 
+48 V phantom power to be provided to the 
MIC 
channel inputs. These switches are arranged so that 
one switch controls the phantom power for four input 
channels (1 through 4, 5 through 8, 9 through 12, and 
13 through 16).
Other analog I/O
These inputs and outputs provide analog feeds to 
monitoring systems, etc.a balanced pair of stereo 
master outputs and an insert loop for these outputs.
There are also four assignable sends and returns, as 
explained in “Setting up the I/O” on page 36.
6MONITOR OUTPUTS [CR (BAL)] These 
1/4” balanced analog outputs are used to provide 
monitoring signals to the control room as selected using the monitor select switches (+4 dBu nominal 
level).
7STEREO OUTPUT This pair of balanced 
XLR connectors provides the analog stereo out signal 
at +4 dBu. 
8MONITOR OUTPUTS [STUDIO] These 
unbalanced RCA connectors provide unbalanced sig-
nals to the studio at a nominal output level of
–10 dBV. 
92-TR IN These two RCA unbalanced inputs 
are typically used for monitoring the replay from an 
analog mastering device at a nominal input level of 
–10 dBV. 
ASTEREO OUTPUT [INSERT] These 1/4” 
TRS connectors provide insert facilities for the 
STEREO OUTPUTs. The send (level –2 dBu) is post 
DA convertor and the return (level –2 dBu) is imme-
diately before outputs.

BASSIGNABLE SENDS These balanced 
1/4” jacks (–2 dBu) are used either as insert sends for 
the input channels or as aux sends (see “Setting up 
the I/O” on page 36).
CASSIGNABLE RETURNS (BAL) These 
quasi-balanced returns (–2 dBu) are either used as aux returns or as insert returns for the input channels 
(see “Setting up the I/O” on page 36).
DPHONES These two stereo 1/4” jacks provide 
headphone outputs.
Module control section
This section is chiefly used for the control of the 
most commonly-used module parameters:
EFS indicators These indicators show the 
current sampling frequency used by the system.
F2ND F. (MOVE) key This key is mainly 
used in conjunction with the automation (purple) 
keys to access the secondary functions of these keys.
GEQUALIZER keys As explained in “Rotary 
encoders (ring LEDs)” on page 15, four of these keys 
(
HIGH, HI MID, LOW MID, LOW) are used to select 
the frequency band of the active module which will 
be affected by the rotary encoders. The 
ON key turns 
the EQ on and off for the selected module.
HCH ASSIGN keys These keys are used to 
assign the selected module to the pairs of output bus-ses (
BUSS 1-2, BUSS 3-4, BUSS 5-6 and BUSS 7-8) 
or to the stereo outputs (
STEREO) or to direct output
