Wiring Considerations

Audio/Video Cables

There is debate over the audible effects of different types of intercon-

nects. Good engineering practices have minimized the effect that

cables might have on the inputs and outputs of the MC-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

application — 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.

Speaker Connections

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 spe-

cific to your components.

Audio/Video Connections

Before making any connections, turn off ALL audio and video compo-

nents, including individual power amplifiers. (Unplug any components

that don’t have power switches.)

The MC-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 satellite receiver

with an optical digital output, 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 compo-

nents used. Consult your dealer for details on your particular require-

ments.
