DC-2 Digital Controller
Installation
The DC-2 has five composite and S-Video inputs. Connection to an S-Video
input will override the composite signal connected via the RCA-type
connector. Note that an S-Video input will be output on both the composite
and S-Video outputs. Composite input signals will not be output as S-Video.
You can assign any video source to any (or all) of the eight DC-2 inputs via
the Input Configuration submenu of the Setup menu. This can be very
useful in systems which use a VCR as the tuner for TV viewing, as the video
feed from the VCR can be assigned to both the VCR and TV inputs. The
VCR's audio signals can be fed to both inputs with Y-connectors. (Do not use
Y-connectors on video signals.) This allows the audio and video signals
from the VCR to be used for both TV and VCR viewing.
You can also assign any video source to audio-only sources such as an AM/
FM tuner, to enjoy music from another source while viewing a video source.
It is important to remember that the impedance characteristics of composite
video and digital audio are different from analog audio. You should only
use cables specifically designed for video and digital audio. Consult your
dealer for recommendations.
The DC-2 has eight digital audio inputs: five coax via RCA and three optical
via TOSLINK™. The digital inputs can be set up to be selected with any (or
all) of the eight inputs via the Input Configuration menu. Using the digital
inputs will always provide superior performance.
Note that "AC-3 ready" laser disc and LD/DVD players output Dolby
Digital (AC-3) data from laser discs on a separate RCA jack in Radio
Frequency (RF) form. To maintain the exceptional performance of the DC-
2, an outboard demodulator is required to turn this RF signal back into a
digital bitstream. By performing the necessary demodulation outside the
DC-2, the potential for RF interference is eliminated. The Lexicon LDD-1 is
an excellent example of one such device.
