Tascam DM-24 User Manual

Return sources are available for channels 1 through 
24 (channels 25 through 32 are input only).

The return options for each group of eight channels 
are selected by moving the cursor to the 

RETURN

 field 

at the left of the list of channels, and using the dial to 
select from the available options.

Press 

 to confirm the setting.

If a slot card has not been fitted, an error message 
appears. Press ENTER to dismiss the message.

Each group of eight channels is assigned to use the 
same return source block (though it is possible to mix 
inputs and returns within the same block).

It is important to note the following:

• The returns from TDIF1-1 cannot be assigned and 

used at the same time as the returns from a card fit-
ted in slot 1.

• The returns from TDIF1-2 cannot be assigned and 

used at the same time as the returns from a card fit-
ted in slot 2.

• The returns from TDIF1-3 cannot be assigned and 

used at the same time as the returns from the inter-
nal ADAT connector.

The first 24 channels may have the following sources 
assigned to them as returns:

As can be seen, it is possible for the same return to be 
assigned to more than one channel at the same time 
(of course, it is not possible for one channel to accept 
the signal from more than one return at the same 
time).

Although the return module for each block can be 
selected, the channels of the module cannot be 
changed. For example, if an MTR return is assigned 
to channels 1–8, track 2 of an MTR cannot be 
assigned to channel 1. Track 3 can only be assigned 
to TDIF channel 3 (in the TDIF1, TDIF2, TDIF3 
return source blocks), or ADAT channel 3, etc.

Note, though that when slot cards are fitted, the num-
ber of the channel in the slot card may be offset by 8 
or 16, so that channel 9 (or 17) of slot card 2 may be 
assigned to channel 1, etc.

Each digital input has two connectors; an XLR-type 
connector and an RCA pin jack. One of these is 
selected for input as described here.

These connectors can both be used for either AES/
EBU or SPDIF data, and the data format is automati-
cally detected by the DM-24—no settings are neces-
sary to choose the data format.

See “The FORMAT screen” on page 26 for details of 
how to set the parameters for sampling frequency 
conversion, etc. at these inputs.

However, although there are two physical connectors 
for these inputs, the audio data for an input can only 
be accepted from one of these connectors at any one 
time.
