Digital Bussing; A Digital Input - Alesis BRC Reference Manual

Like all other locate changes, the song setup information is not
actually deleted from the tape until you save the setup to tape,
assuming you have already saved the setup at some point before
deleting the song (see section 5.2). If you accidentally deleted a song,
you could retrieve it by loading the setup data back from tape. Of
course, deleting a song will never erase audio on tape.

4.7 DIGITAL BUSSING

The DIGITAL I/O button is used to enable/disable digital audio
routing. This function is used to route the digital track information
for the purposes of track copying and AES/EBU or S/PDIF input
and/or output. When Digital I/O is enabled, its LED will light and the
current digital inputs can be recorded to tape (all channels are
received through the one fiber optic connector) and the analog inputs
will be ignored. The type of digital input that is enabled by this
button depends upon the type of digital input that is selected when
this function is edited.
