B&K AVR305, AVR307 DIGITAL CONNECTIONS, DT-1

DIGITAL CONNECTIONS
Connect digital inputs (DVD, VLD, etc.) to the rec eiver. 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 appropr iate 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 enc ode 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 selec t 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 c oaxial or optical input. Connect the DT -1’s c oaxial output
to the desired coaxial digital input on your receiver.
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 rec or der to the coaxial. Zone 2 (B) digital output
is coax.
