1 – Introduction—Word clock issues
 TASCAM DM-24 Reference Manual 11
Word clock issues
The “word clock” in a digital audio system is the tim-
ing information that enables the digital audio sam-
ples in a system to be synchronized between the 
different devices. It is completely unconnected with 
timecode clocks, etc.
There must be one, and only one, word clock master 
device in a digital audio system. The DM-24 is capa-
ble of acting as a word clock master or as a slave.
WARNING
There should be one, and...

2 – User interface
Scope of controls
The DM-24 has three main types of control screen: 
system screens, which control parameters for the 
whole of the system, “global” control screens which affect a certain parameter for a number of channels or 
modules at once, and the “module” control screens 
controlling all the parameters for one module.
Global screens
As the name suggests, the “global” screens allow you 
to see all the parameters for many channels (the pre-
post...

5Use the cursor keys, the soft keys and the 
PODs to make changes to the module’s 
parameters. See below for details.
PODs 
The DM-24 features four rotary controls immedi-
ately below the screen, called PODs. 
These are used as “soft” controls to adjust parame-
ters; that is, they have no fixed assignment to control 
any single parameter in the console, but are used to 
control a parameter which is currently highlighted on 
screen....

Other ways of changing values
The JOG/DATA dial can also be used to change 
parameter values.
1Use the cursor keys to move the cursor 
(sometimes shown by a blinking thick box 
surrounding the parameter to be changed, 
and sometimes by a 
ƒ symbol beside the 
parameter to be changed.
2When the parameter to be changed is high-
lighted as described above, use the entry dial 
to set the value (it starts to flash), and the 
ENTER key to...

Soft keys
At the bottom of a display screen, there may be some 
“tabs” displayed, which lead to further related 
screens or pre-defined action.The four keys at the bottom of the screen, beside the 
PODs, are used as “soft keys” to jump to the screens 
shown on the “tabs”. In this example, the 
MONITOR 
and 
OSC/COM tabs are controlled by soft keys 2 and 3.
NOTE
It is also possible to jump to the different screens by...

EQ gain controls, where the gain of the four EQ 
bands is adjusted using these encoders. The 
encoder 
EQ GAIN indicator is lit in this case.
AUX send level controls, where either the encoder 
AUX  1 through 4 indicators or the AUX  5 and 6 
indicators are lit (in the latter case, only the two 
leftmost encoders have any function).See the appropriate section on module operations 
(“Module operations” on page 49) for full...

filter mode). Low Q values affect a wide portion of 
the spectrum, as shown below: and high values affect a narrow frequency band:
Note that “intermediate values” are shown on the 
encoders by dimmed LEDs, as above. The LED pat-
tern in Q mode is always symmetrical about the 
upper center indicator.
Encoders used as pan controls
When the encoders are used to make pan settings, the 
center pan position is represented in the...

2 – User interface—Fader layers
18 TASCAM DM-24 Reference Manual
When two aux channels are linked together, the 
encoders work in a slightly different way for the 
selected channel. The first encoder (
GAIN) controls 
the pan for the first two aux sends (
1-2 or 5-6) and 
the second (
FREQ) controls the level for these sends. 
The third (
Q) and fourth (PA N) control the pan and 
level respectively for aux sends 
3-4 in the first AUX encoder setting (they have no effect in the second 
AUX encoder...

undo/redo function of the library. This key is the 2ND 
F.
 key (above and to the left of the rotary encoders). 
These second functions are labeled below the key in 
inverse lettering:
To use these second functions, press and hold the 
2ND F. key and press the key whose second function 
is to be used.The 
AUTOMATION UNDO key is used in automation 
operations in order to undo any unwanted changes to 
automated mixes.

3 – System-wide options
The DM-24 provides a number of options which con-
trol the overall functionality of the console.
These are accessed through the 
OPTION and DIGITAL 
screens.
Within these screens, you can (in the 
OPTION screen):
 Set up various interface preferences
 Set up the way in which soloing works Set up timecode preferences for synchronization 
with other units
and in the 
DIGITAL screen
 Set up the word sync clock
 Choose the digital input and output...
