DIGITAL CONNECTIONS
Connect digital inputs (DVD, VLD, etc.) to the receiver. You will need either coaxial or optical digital inputs to play
Dolby Digital (AC-3) or DTS surround sound processing. Digital connections are also recommended for PCM
sources. If your source has both optical and coaxial outputs connect only one.
Coaxial digital inputs - standard RCA type connectors.
Attach one end of your digital coaxial cable to your
source coaxial digital out and the other end to the
appropriate receiver coaxial digital (orange) input.
Optical digital inputs - First, remove the cap on
the optical digital input. Save the cap. Attach one
end of your digital optical cable to your source and
the other end to the appropriate digital input on the
back of the receiver.
Connecting A Laser disc Player - Dolby Digital
(AC-3) laser discs use a special technique called AC-
3 RF to encode the Dolby Digital bitstream. If the
laser disc player is capable of playing back Dolby
Digital discs it will have a separate output for this
bitstream in addition to the normal coaxial and/or
optical outputs. Do not connect the AC3-RF output
directly to your receiver. The AC-3 RF bitstream
must first be converted to a normal (non-RF) Dolby
Digital type signal. It is recommended that a B&K
DT-1 be used to convert and select between the
Laser’s AC-3 RF and PCM/DTS signals. The output
from a DT-1 will automatically select between the
connected PCM/DTS bitstreams and the converted
AC-3 RF Dolby Digital signal. Other AC-3 RF to
Dolby Digital decoders may not make this switch
automatically. Connect the laser disc’s AC3-RF output to the DT-1’s AC-3 RF input. Connect either the laser disc
player’s PCM coaxial or optical digital output (not both) to the DT-1’s coaxial or optical input. Connect the DT-1’s
coaxial output to the desired coaxial digital input on your receiver.
Digital Outputs - Separate
and independent coax digital
outputs are available for
Zone 1 and Zone 2. Connect
to a digital recorder (CD-R,
mini disc, DAT, personal
computer, etc.) These signals
are the same as the incoming
digital signal from the
selected source on each
zone. If your digital recorder
has both optical and coaxial
inputs you need only connect
one. Zone 1 selected digital
input is converted to both
coaxial and optical. You may
connect one digital recorder
to the optical output and
another recorder to the coaxial.
Zone 2 digital output is coax.
