the
DIGITAL I/O2
port
➀
. They are then passed
straight through to the
DIGITAL I/O2
port connected
to the mixer
➁
.
If necessary, other analog inputs (e.g. MIDI-sequenced
instruments) may be played through channels 1
through 8 of the mixer simultaneously with the
replayed digital tracks from the DTRS recorder.
The advantage of using the MA-AD8 in this situation
is that the digital audio cabling is permanent—no dis-
connection and re-connection of cables needs to be
done, and the MA-AD8’s front panel switches provide
convenient re-routing facilities.
