In 2-input mode, inputs 3-8 are disconnected and cannot be recorded or
heard. In 4-input mode, inputs 5-8 are similarly disconnected. To use all

To record from the digital input, press the [DIGITAL INPUT] button;
the DIGITAL icon in the INPUT icon group will light. The digital
input can be used to record from another XT20 or ADAT-compatible
optical signal. All eight channels will be received via the fiber optic
connection (see Digital In/Out in Chapter 3) and the analog inputs will
be ignored. However, 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 digital track bouncing, see chapter 5.

The [TRACK COPY] button is used to digitally bounce tracks within a
single XT20. To digitally bounce tracks, you must first press [TRACK
COPY]; the TRK COPY icon in the INPUT icon group will light.
Next, select the source tracks, select (record enable) the destination
tracks, and initiate recording. The track copies will be an exact
duplicate of the original (i.e. it is exactly aligned with the original
and is an exact clone).
While holding the [TRACK COPY] button, the track's INPUT LEDs
will indicate the selected source channel(s). While still holding the
[TRACK COPY] button, the source tracks may be selected and de-
selected by pressing the RECORD ENABLE buttons [1] – [8]. Releasing
the [TRACK COPY] button will return the channel REC and INPUT
indicators and RECORD ENABLE buttons to their normal status. At
this point, you may record-enable the destination tracks (see next
section).
When copying tracks:
• The source tracks will be recorded onto the destination tracks in
ascending order. Example: If source tracks 1 and 3 are selected and
tracks 5 and 6 are record enabled, then track 1 will be copied to track 5
and track 3 to track 6.
• If more destination tracks are selected than source tracks, the
source tracks will repeat (cycle). Example: If tracks 7 and 8 were added
to the destination tracks of the previous example, then track 1 would be
copied to tracks 5 and 7 and track 3 would be copied to tracks 6 and 8.
This scheme also allows for copying a single track to multiple tracks.
• Since no more than 4 tracks may be copied within a single
machine, a maximum of 4 source tracks will be allowed. This means
that if 4 source tracks are already selected, then no other tracks can be
selected until one of the 4 tracks is de-selected.
