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
tempera ture. Tur ning 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 th e 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

green activity LED remains
illuminated when the unit is
placed in Standby.
