Digital Input Status Detection; Record/Zone 2 Operation - Lexicon DC-1 - REV 1 Owner's Manual

DC-1 Digital Controller
If digital audio input is selected without a valid source, or if a digital error
state which affects audio performance is detected, all audio outputs are
muted and an error message is displayed. Muting is also activated on
receipt of digital data encoded as "non-audio data". While audio is muted,
the message OUT OF LOCK ERROR or NON-AUDIO DATA is displayed
fot two seconds. The associated input on the front panel will display a
blinking red LED while the error conditionpersists. When valid data is
restored, the error message is cleared and the unit returns to normal
operation. Whenever Emphasis is detected within the incoming digital
audio channel status bits, de-emphasis is automatically applied.
The DC-1 offers independent input selection and level control for the Main
and Zone 2 outputs. Three different methods of control are described below.
(Note that Record and Zone 2 outputs are in parallel, so input selection for
Zone 2 will effect identical changes at the Record outputs.)
Zone 2 controls available during normal operation
In normal operation, pressing RECORD/ZONE 2 on the remote control or
the front panel will assign the current input selection to the Record/ Zone
2 outputs without affecting the Main outputs. Holding down RECORD/
ZONE 2 allows Zone 2 adjustment of VOLUME and MUTE without
affecting the Main outputs. To de-assign the Record/Zone 2 outputs,
simply press and hold RECORD/ZONE 2 again.
For example:
VCR2 is selected for the Main outputs and its associated green front panel
LED is illuminated. Pressing and holding down the front panel
REC/ZONE 2 button will light the red LEDs above the REC/ZONE 2
button and the currently selected input (in this example, VCR2). The display
will show:
SELECTED FOR RECORD
Pressing REC/ZONE 2 again will cause the red LEDs to go out, and will
display:
To assign a different input via the front panel, simultaneously press
REC/ZONE 2 and the desired input selector. To change the input assign-
ment via the remote, first de-assign the current input by holding down the
RECORD/ZONE 2 key, then press the desired input selector. This will
change the input assignment for the Main outputs. Assign this new input to
the Record/Zone 2 outputs by pressing and holding RECORD/ZONE 2.
As protection against feedback, the TAPE and VCR1 inputs are normally
blocked from being used as sources for the Record and Zone 2 outputs. This
default condition can be changed in the Setup menu.
