Connecting a Laserdisc Player
Connect the AC-3 RF output of the LD player LD RF input of
the preamp/processor.
IMPORTANT NOTE: Do not connect a normal analog audio
output or digital coaxial output of a DVD player or any
other source to the LD RF jack. You will damage the
preamp/processor if you do.
Also connect the left and right analog audio outputs of the
LD player to the Left and Right LD analog inputs on the
preamp/processor. This will
allow you to hear laser discs
that do not have Dolby Digital
AC-3 soundtracks.
Early LD players only have
analog audio outputs and are not
capable of delivering 5.1 channel
Dolby Digital surround sound. If
your LD player does not have a
jack marked “RF AC-3 Out,” just
hook up the Left and Right
analog audio outputs of the LD
player to the analog LD inputs on
the preamp/processor. If you
have any doubts as to whether
your LD player has a Dolby
Digital (AC-3) RF output, contact
your Polk Audio dealer.
Connect either the composite
video or the S-video output of the LD player
to the corresponding LD video input of the
preamp/processor. Do not use both composite
and S-video connections. If you use S-video
connections here, you must connect your
TV to the preamp/processor with an S-video
cable in order to get a picture with this input.
Connecting Your TV to the Preamp/Processor
If you are using only standard (composite RCA) video inputs for your
video sources and no S-video sources, just connect the VIDEO TV
out to any free composite video input of your TV. If you are using only
S-VHS (S-video) video inputs for your video sources and no standard
(composite) sources, just connect the VIDEO TV out to any free S-video
input of your TV.
If you want the audio from your TV to play through the system, just
connect its audio outputs to any unused set of analog input jacks on the
preamp/processor, such as LD, AUX (on the front panel), or Tape In.
Connecting the Preamp/Processor to the Subwoofer
Use the supplied 4 meter (13 1/4 ') 25-pin audio cable to connect the
AUDIO OUT of the DS-2 preamp/processor to the AUDIO IN 25-pin
connector on the subwoofer. IMPORTANT NOTE: If the cable is not long
enough, you may add a 4 meter Monster Cable
® brand DB25HT Audio
Interconnect cable (or equivalent) to increase the length to 8 meters.
Contact your Polk dealer or call Polk Audio (800) 638-7276, ext. 324,
Monday through Friday, Eastern Standard Time, and buy an actual Polk
cable direct from us. MORE IMPORTANT NOTE: While the 25-pin
connector cable may look like your average computer printer cable,
it is not a printer cable. Do not try to use a computer printer cable
to connect your DS-2 system. This will damage your DS-2. And
you still won’t be able to print out that important report through
your subwoofer.
