High sampling frequency considerations
NOTE
When cascading, all units must either be in high sam-
pling frequency mode or all units must be in normal 
sampling frequency mode.
Because of the reduced number of aux sends, the cas-
cade screen changes when the high-frequency mode 
is selected, as shown here:
TDIF-1 card
The optional TDIF-1 card provides an additional 
eight channels of I/O (four in high sampling fre-
quency mode).As with the...

AES3 card
This card allows for the connection of up to four AES 
input and four output lines.In normal sampling frequency mode, this provides 
eight audio channels in each direction, and in high 
sampling frequency mode, it provides four channels 
in each direction.
Input options
The inputs may be selected as return sources for 
channels (“Assigning inputs to channels” on page 38) 
and the outputs of the cards may be selected as either 
buss or aux...

16 – Options—AD/DA card
 TASCAM DM-24 Reference Manual 123
The NORMAL option is not available for either input 
or output in this mode.AES/EBU is the only available output format.
AD/DA card
This card provides eight balanced channels of analog 
input and eight balanced channels of analog output, 
converted at up to 24-bit resolution (the resolution is 
displayed here, but cannot be changed).The eight output tracks associated with this card can 
be selected (1-8, 9-16, 17-24).
Remember that if this card...
