INPUT SELECT
There are three buttons for input select options. These three buttons are labeled
[ANALOG INPUT], [DIGITAL INPUT], and [TRACK COPY]. These determine what
signals will be recorded on the XT. The currently selected input mode is indicated in
the lower right corner of the display: ANALOG, DIGITAL or TRK COPY.
While any of the Input Select buttons are being held, the channel record and input
status indicators no longer indicate the current record or input status, and the REC
icon turns off. As long as one of these buttons is being held, the tracks’ INPUT LED
is used to indicate channel selection for that particular function, and the RECORD
ENABLE buttons [1] – [8] are used to select and de-select channels (see page 41).

ANALOG INPUT

Pressing the [ANALOG INPUT] button once selects the analog inputs (both
unbalanced and balanced) for recording and monitoring; the ANALOG icon will light
in the INPUT icon group in the display. While holding the [ANALOG INPUT] button,
the channel input indicators will show the number of analog inputs that are currently
selected. There are three selections possible: Two inputs, four inputs, or eight
inputs. This allows you to record from a 2 or 4 bus mixing console without repatching.
To choose 2-input mode: Press either the channel 1 or 2 RECORD ENABLE
buttons while holding [ANALOG INPUT]. This will cause both the channel 1 and 2
input lights to light up, indicating that only input channels 1 and 2 will be used. If
any of tracks 1, 3, 5, or 7 are record enabled, they will receive their input signal
from the analog input of channel 1. If any of tracks 2, 4, 6, or 8 are record
enabled, they will receive their input signal from the analog input of channel 2.
To choose 4-input mode: Press RECORD ENABLE button 3 or 4 while holding
the [ANALOG INPUT] button. This will cause channels 1 through 4 INPUT LEDs
to light up, indicating that only input channels 1 thru 4 will be used. In this case,
channels 5 through 8 receive their input from channels 1 through 4, respectively.
To choose 8-input (the most common) mode: Press RECORD ENABLE button 5
thru 8 while holding the [ANALOG INPUT] button. This will cause all eight track
INPUT LEDs to light. In this mode, each track receives its signal from its own input.
J

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 inputs, 8-input mode

must be selected.

DIGITAL INPUT

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 XT 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, page 59.
