DIGITAL CONNECTIONS
Connect digital inputs (DVD, VLD, etc.) to the processor. 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 processor 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 processor.
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 processor. 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 processor.
Digital Outputs -
Separate
and independent coax
digital outputs are available
for Zone 1 (A) and Zone 2
(B). 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 (A) 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 (B) digital output
is coax.
