Choose Analog Or Digital Input; Digital Input Re-Routing - Alesis ADAT-LX20 Reference Manual

Record and Playback Basics - Chapter 4
The reason for these three modes is to take equal advantage of 2, 4 and 8 bus mixing
consoles. To select the appropriate Input Mode, hold the ANALOG INPUT button
and press one of the RECORD ENABLE buttons (1–8). The blue INPUT indicators,
located along the bottom of the display below the VU meters, will illuminate to
indicate the selected Input Mode.

When using a 2-bus mixer, connect its two outputs to the LX20's unbalanced inputs 1
and 2, and select 2-Input Mode. Any time you want to record on an odd-numbered
track, route the signal(s) to bus #1 or left. Likewise, to record onto an even-numbered
track, route the signal(s) to bus #2 or right. By simply putting the desired track into
record, the proper signal will get there, even though it is not connected directly to
the track's input jack.
When using a 4-bus mixer, connect its four outputs to the LX20's unbalanced inputs 1
through 4, and select 4-Input Mode. To record on track 1 or 5, route the signal(s) to
bus #1. Likewise, to record onto tracks 2 or 6, route the signal(s) to bus #2, and so on.
With an 8-bus mixer, connect each bus to its like-numbered input. To record on track
1, send the signal to mixer bus 1, to record on track 2 send the signal to mixer bus 2,
etc.
8-input mode is also recommended when feeding the LX20 from a mixer channels'
direct outs.

Choosing Digital Input may involve setting the Clock parameter as well,
depending on whether the LX20 is the "master" or "slave" in a digital setup. See
Chapter 10, "Digital Clock Considerations".

By holding the DIGITAL INPUT button, you may reroute incoming channels to
record on different tracks. Example: Digital audio received on channels 1 and 2 can
be rerouted and recorded onto tracks 3 and 4. For more information about recording
from the digital input and re-routing, see Chapter 10.
