DIGITAL CONNECTIONS
Connect digital inputs (DVD, VLD, etc.) to the A/V System Controller. 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 A/V System Controller coaxial
digital (orange) input.
3.5 mm
coaxial digital input - You may connect the V3 coaxial input using a
3.5 mm mono jack instead of the RCA type jack. This input works the
same as the other digital inputs but uses a 3.5 mm mono jack instead
of an RCA. The plug must be wired as tip (+) and the long barrel
section (-).
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 A/V System Controller.
Connecting A Laserdisc Player - Dolby Digital
(AC-3) laserdiscs use a special technique called
AC-3 RF to encode the Dolby Digital bitstream. If the
laserdisc 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 A/V System Controller. 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 laserdisc’s AC3-RF output to the DT-1’s AC-3 RF input. Connect either the laserdisc 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 A/V System Controller.
Digital Outputs - Connect to a digital recorder (CD-R,
minidisc, DAT, personal computer, etc.) This signal is
the same as the incoming digital signal from the
selected source. If your digital recorder has both
optical and coaxial inputs you need only connect one.
The A/V System Controller converts optical to coaxial
and coaxial to optical. You can connect one digital
recorder to the optical output and another recorder to
the coaxial. The coaxial connector is a 3.5 mm type for
direct connection to a personal computer. You will
need an adapter to connect the 3.5mm type to a
standard RCA type coaxial input
