Controls and
Indicators
The Front Panel
1. ON/OFF
ON/OFF alternately puts the
DC-1 into and out of standby
mode. Turning the DC-1 off
with this button (or with the
remote) deactivates the unit
while leaving power to the
signal processing circuitry to
keep it at optimum operating
temperature. Turning the
DC-1 on with this button (or
the remote) will restore the
previous operating state.
2. Input Selection
Pressing any of these but-
tons (VCR1, VCR2, V DISC,
TV, AUX, CD, TUNER, TAPE)
selects the input at the corre-
sponding rear panel connec-
tor as the current input selec-
tion and lights a green LED.
3. REC/ZONE 2
Selects and deselects the
current input source for the
RECORD and ZONE 2 out-
puts. When the REC/ZONE 2
function is engaged, the red
LEDs are lit on the REC/
ZONE 2 button and on the
selected source input button.
To change the REC/ZONE 2
source, press and hold down
REC/ZONE 2 while pressing
another input selector.
Some specific record sources
are disallowed because of the
potential for feedback loops.
By default these are TAPE
and VCR1. If a prohibited
source is selected, an error
message is displayed. The
prohibited REC/ZONE 2
source choices can be
changed in the Setup menu.
4. EFFECT
Displays the current effect,
then steps through all avail-
able effects.
5. BYPASS
Toggles the selected effect
on and off. The stereo analog
or digital inputs are fed un-
processed to the front left,
front right and subwoofer out-
puts while all other amplifier
outputs are muted. A front
panel LED will light yellow
and screen messages indi-
cate bypass is engaged.
6. MUTE
Attenuates all audio outputs
except for RECORD or ZONE
2, lights a red LED, and dis-
plays a screen message to
indicate mute is engaged. The
attenuation level can be set in
the Setup menu.
7. IR Receiver and LED
The IR receiver has an asso-
ciated activity LED that lights
green when valid IR signals
are received, and an LED that
lights red to indicate an over-
load condition at the inputs or
within the DSP path. An IR
input jack is available on the
rear panel for a remote
mounted IR receiver. The
green activity LED remains
illuminated when the unit is
placed in Standby.
8. Display
A 2x20 backlit amber LCD
displays the result of user
action and the current status.
9. VOLUME
A position independent ro-
tary encoder provides volume
adjustment of all outputs, ex-
cept for RECORD or ZONE2.
Screen displays show a vol-
ume bar and level in dB.
