The Rear Panel - Lexicon DC-1 - REV 1 Owner's Manual

Installation and
Calibration

The Rear Panel

CAUTION: Never make or break any connections to the DC-1 with the
rear-panel power ON. Make sure any associated amplifiers have been
turned off for at least one minute before turning this master power
switch on or off.
1. AUDIO INPUTS
Eight stereo analog audio in-
puts are switched with corre-
sponding video inputs and fed
to the Monitor outputs. Inputs
are nominally labeled as origi-
nating from an audio tape
player, tuner, CD player, an
unspecified auxiliary source,
a TV tuner, a Laser or Video
Disc player, a secondary, and
a primary VCR.
2. ZONE2 and RECORD
Each pair of stereo audio
outputs supplies the same
signal according to the record
input selection. ZONE2 sig-
nal levels can be controlled
independently for use with a
second set of amplifiers and
speakers in another room.
ZONE2 can also be used as
a second record output. When
the output for ZONE2 is set to
0dB (unity gain), it has the
same output level as
RECORD. RECORD can be
expanded to two outputs us-
ing standard Y-connectors.
Both outputs are muted in
standby.

3. MAIN OUTPUTS
Three stereo amplifier out-
puts are provided for front,
side and rear speakers.
Single monaural outputs are
provided for the center
speaker and the subwoofer.
The audio outputs are muted
in standby.
4. S/PDIF INPUTS
Two coaxial RCA connectors
and two optical connectors
are provided for digital audio
in the S/PDIF format at a
44.1kHz +1000 ppm sample
rate.
5. REMOTES:
IR IN, PWR CTL
The IR input is a miniature
phone jack connector for in-
put of modulated IR receiver
data from an externally
mounted IR LED receiver.
Data is retransmitted by an
IR LED mounted near the
front panel IR receiver.
To prevent a feedback loop with the record outputs, VCR1 and
TAPE are normally restricted from assignment as record outputs.
TAPE, TUNER, and CD default to VCR1 as a video input. Any input
label and its default status can be changed in the Setup menu.
The Power Control port is a
5-Pin DIN connector. Pins 1
and 2 are ground, pin 3 is
high when unit is on, low in
standby or Off. High is indi-
cated by either +5VDC or
+12VDC, selectable via an
internal jumper. Pin 5 can be
enabled (high) or disabled
(low) for specific input selec-
tions in the Setup menu.
6. VIDEO INPUTS
Five video input sources are
provided. VCR1, VCR2 and
V DISC, have both compos-
ite and S-video capabilities.
(S-video is selected in pref-
erence to the composite sig-
nal.) AUX and TV accept
composite only. Video inputs
are selected with their corre-
sponding audio inputs and
fed to the selected monitor
output jack. Record output
jacks can be selected inde-
pendently.

7. VIDEO OUTPUTS
RCA (composite) and S-video
connectors are provided for
monitor and record. If an S-
video input is used, both S-
video and composite are
available at each output. If
the video input is composite,
only composite is available at
each output. The monitor
output incorporates the on-
screen video overlay. Unless
RECORD is enabled, the
record output follows the
monitor output selection with-
out the on-screen display fea-
ture. Both outputs are blanked
in standby.
8. Power On/Off
Master power switch discon-
nects the AC Mains. This
switch is intended to be left
On during regular use. When-
ever cables are connected or
disconnected, or when the
unit is not going to be used for
an extended period of time,
this switch should be set to
Off.
9. POWER
AC power connector: 2-wire,
10 Amp, IEC 320.
