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 S/PDIF format at a 44.1kHz

+1000 ppm sample rate. The

Dolby Digital version also

accepts 48kHz signals.

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.

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 +12VDC or

+5VDC, selectable via an in-

ternal jumper. (Factory con-

figuration is +12V.) Pin 5 can

be enabled (high) or disabled

(low) for specific input selec-

tions in the Setup menu. See

pinout diagram above.

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: 3-wire,

10 Amp, IEC 320.

To prevent a feedback loop with the Record/Zone 2 outputs, VCR1

and TAPE are normally blocked from assignment as REC/ZONE 2

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.

1 = Ground

2 = Ground

3 = Power On

4 = Unused

5 = Trigger (programmable)

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 75 76
