DC-1 Version 4 Digital Controller Installation

Wiring Considerations

There is debate over the audible effects of different types of interconnects.

Good engineering practices have minimized the effect that cables might

have on the inputs and outputs of the DC-1 — but feel free to evaluate

different interconnects in your system. Be conscious, however, of the

mechanical stress from repeated insertion and overly tight connectors, and

the possibly corrosive nature of some contact-enhancing fluids.

Note that the use of standard audio cables for video or digital audio

applications may cause signal degradation, and is not recommended. For

these connections, please use only cables that are designed for the applica-

tion — these have different impedance characteristics than cables designed

for analog audio applications. Consult your dealer for recommendations.

All cables should be kept as short as possible.

In general, speaker cables should be kept short, and low-impedance wire

should be used throughout to assure efficient power transmission and

avoid audible distortion. Recommended wire lengths are given in the table

below. Although these examples can be used as a general guide, your

system manuals should provide detailed information specific to your

components.

Wire Lengths

up to 12 feet 16 gauge

up to 18 feet 14 gauge

up to 29 feet 12 gauge

up to 51 feet 10 gauge

Audio/Video Cables

Speaker Connections

Before making any connections, turn off ALL audio and video components,

including individual power amplifiers. (Unplug any preamps and power

amps that don’t have power switches.)

The DC-1 is designed to function as the control center of the system,

selecting inputs and controlling the volume of all speakers in the system.

The following diagram shows a system with a tape deck, an AM/FM tuner,

a CD player with a coaxial digital audio output, a cable box, a DVD player

and a VHS VCR. This example shows the tape deck and VCR set up for

recording and dual-zone audio.

Actual system connections will vary widely depending on the components

used. Consult your dealer for details on your particular requirements.
