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-2 — 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
Length AWG Size
up to 12 feet 16 gauge
up to 18 feet 14 gauge
up to 29 feet 12 gauge
up to 51 feet 10 gauge

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-2 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 components
used. Consult your dealer for details on your particular requirements.
