Connection Precautions
• Do not plug the preamp/processor or subwoofer into AC outlets until
all the connections have been made.
• When connecting sources, use either standard composite (good) or S-
video (better) throughout. Do not use both composite and S-video
connections. Use the same type of connection between the
preamp/processor and your TV.
• Connect one cable at a time observing the “input” and “output.”
This will avoid any cross connection between channels and signal
inputs and outputs.
• Insert the plugs securely. Incomplete connections may result in noise
or signal loss.
• We’ve included high quality pre-cut and terminated speaker wire,
and a 25-pin processor-subwoofer cable. To hook up your sources, we
recommend the use of high quality audio and video connecting cables.
See your Polk Audio dealer for specific recommendations.
• Prior to connecting other audio and video equipment to the DS-2,
please read their owners’ manuals.
Connecting Radio Antennas
Connect the supplied FM wire antenna to the FM (75 Ohm) F-type
connector. For better reception connect an indoor or outdoor FM antenna.
The preamp/processor comes supplied with an AM loop antenna that
connects to the GROUND and AM terminals as illustrated. To
use those terminals, unscrew the tabs and insert the antenna’s
bare wires into the holes, then tighten the tabs. To find the best
place to put the AM antenna, tune in a local AM radio station
(see page 22) and move the AM loop antenna around until you
get the clearest reception. You can secure the antenna to a
wall or the inside wall of an equipment cabinet with screws.
Connecting a DVD Player
Connect the coaxial digital output of the DVD player to the DVD
DIGITAL INPUT of the preamp/processor.We recommend that you
also connect the Left and Right analog outputs of the DVD player
to the analog audio DVD inputs of the preamp/processor using
RCA connectors. This will allow you to tape record the audio
output of the DVD player and use the DVD player as an audio
source for a remote room.
Connect either the composite video or the S-video output of the
DVD player to the corresponding DVD 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. If your DVD player has “component” video outputs
(three jacks), you must connect those directly to a TV that has
corresponding “component” video inputs.
A very few DVD players do not have a coaxial (RCA type) digital output but
only an optical cable output. In that case, hook up the DVD player into the
DSS optical digital and analog audio and video inputs. Select “DSS” when
you want to use your DVD player.
OPTION: If the DVD player is also being used as a CD player and there is
no other CD player in the system, you may want to plug the analog audio
outputs of the DVD player into the analog CD inputs rather than the analog
DVD inputs. This allows you to set one bass level for stereo and another
bass level for surround. When you play a CD in the DVD player, push the
CD button on the remote and you will hear the CD with the amount of bass
you previously selected. When you play a DVD movie, push the DVD button
on the remote and you’ll automatically hear the DVD with the bass level
set to another previously set level (generally higher). The one downside of
this hookup is that you will not be able to record DVD movies to your VCR.
That is copyright infringement and you shouldn’t be doing it anyway. Don’t
you read those FBI warnings at the beginning of every DVD?
