ENTER.After making a “global” setting in this way, use the 
cursor keys and PODs to trim the individual channel 
levels as desired.
It is also possible to use the faders to control the

15 – High sampling frequency
The way in which the DM-24 operates in high sam-
pling frequency mode (88.2k and 96k) is slightly dif-
ferent in many cases to the operation in normal 
sampling frequency mode (44.1k and 48k).
This section describes the differences between high 
sampling frequency mode and normal sampling fre-
quency mode.The high sampling frequency can be obtained inter-
nally, when the DM-24 acts as the word sync clock 
for the whole of the audio system, or...

 TASCAM DM-24 Reference Manual 113
DUAL-LINE is a “parallel” method, in which a pair of 
AES/EBU cables send two channels of high sam-
pling frequency audio data.
HIGH-SPEED uses one AES/EBU cable to send two 
channels of audio data at twice the standard data rate.
In this screen, the output format of the four AES/
EBU input streams available to the DM-24 can be 
selected to be either high-speed or dual-line, depend-
ing on the capabilities of the other...

High sampling frequency I/O
The following explains how the I/O assignments are 
changed when high sampling frequency is selected.
Instead of being divided into groups of eight, as in 
the usual assignment screens (“Setting up the I/O” on 
page 36), these are selected using groups of four, as 
shown in the figure above.
Eight channels are shown on screen at one time.
The second group of eight channels (the second four 
of which...

15 – High sampling frequency—Monitoring
 TASCAM DM-24 Reference Manual 115
Monitoring
The monitoring system in this mode is very similar to 
the normal mode:The difference is in the choice of the destinations for 
the oscillator and the talkback slate (there are only 
four aux sends available for the destination). See 
“Slate settings” on page 77 and “Lineup oscillator” 
on page 77 for further details of slate and oscillator 
operations.
Aux sends
Since there are only four aux sends, the aux send...

15 – High sampling frequency—Grouping
116 TASCAM DM-24 Reference Manual
Grouping
Mute and fader groups are displayed also slightly dif-
ferently on account of the reduced number of chan-
nels, as shown here:The mute grouping is shown here, but the fader 
grouping is almost identical.
When the change is made between high sampling 
frequency and normal sampling frequency modes, 
the console reverts to “neutral settings” and the cur-
rent groupings are no longer valid.
For details of how to operate these...

15 – High sampling frequency—Other screens
 TASCAM DM-24 Reference Manual 117
Other screens
Throughout the operation of the DM-24, whenever a 
normal sampling frequency screen displays 32 chan-
nels, or provides facilities for 32 channels, in high-
frequency mode this will be halved to 16.
For example, in this screen, the meter layer cannot 
follow channels 17 through 32 (they do not exist) and 
therefore the option is not available.Also, since there are only four aux sends available in 
high sampling...

The DM-24 can be expanded by means of cards (one 
or two) installed in the expansion slots.
WARNING
Regarding installation, consult your nearest TASCAM 
dealer.
Do not install options by yourself which require open-
ing the DM-24 or you will lose your warranty.
You will need a cross-head (Phillips) screwdriver.
1Turn off the DM-24 and disconnect it from 
the power supply. Disconnect all other equip-
ment connected to it.
WARNINGWARNING
The above step is most...

16 – Options—Cascade card
 TASCAM DM-24 Reference Manual 119
Cascade card
This card allows the connection of two DM-24 units 
to increase the number of channels, etc. available. A 
cascade card must be fitted in slot 1 of each unit to be 
cascaded.
In a cascade chain, one unit is designated as the mas-
ter unit, and the other as a slave. The master unit 
must always act as the word sync master for the cas-
cade chain (though it can act as a word sync slave in 
the overall audio system).
There is one...

Typically, monitoring and stereo outputs should be 
connected to the cascade master, but there are a num-
ber of occasions when these outputs may be used 
from the slave as well as from the master.
For example:
 Using the stereo buss of both units would allow the 
stereo buss of one unit to be used dry, with the 
other unit’s stereo buss being processed (compres-
sor, etc.). The digital outputs (AES/EBU, SPDIF), together 
with the balanced...
