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.

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.

Both outputs are muted in

standby.

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.

9. POWER

AC power connector: 3-wire, 10 Amp, IEC 320.
