SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS
and is turned on, and the LED is lit amber to
indicate that no signal is being received and
the Subwfr is in Standby mode.
When the Music-Sense On/Off Switch £
is in the ON position, the LED will be
lit blue, whether or not an audio signal is
present.
When the Master Power Switch ª is
turned off, the LED goes dark, no matter
which position the Music-Sense On/Off
Switch £ is in.
¢ Phase Switch: This switch determines
whether the subwoofer's piston-
like action moves in and out in phase with
the main speakers. If the speakers were to
play out of phase, the sound waves pro-
duced by the subwoofer would be cancelled
out, reducing bass response. This phenome-
non depends in part on the relative place-
ment of the speakers in the room. In most
cases, the Phase Switch ¢ should be left
in the NORMAL position. However, it
does no harm to experiment with the Phase
Switch ¢, and you may leave it in the
position that maximizes bass response.
∞ Line-Level Subwoofer (SUB) Input:
Connect the subwoofer output of a receiver
with digital surround sound decoding, such
as Dolby* Digital or DTS
input bypasses the Subwfr's internal
crossover circuitry, and should only be used
with a filtered signal. If your receiver does not
have digital decoding, you should use the
Line-Level Full-Range Inputs § instead.
§ Line-Level Full-Range Inputs: Connect
the line-level subwoofer output or preamp out-
put(s) of your receiver or amplifier to these
inputs. If your receiver does not have a sepa-
rate subwoofer output, use a Y-adapter (not
supplied) to bridge the receiver's preamp out-
put to the main amp input for that channel,
and connect the long end of the adapter
to the corresponding line-level input on the
Subwfr. If your receiver has only a single
subwoofer output, you may connect it to
either the left or right line-level input on the
Subwfr, and no Y-adapter is needed.
¶ Speaker-Level Outputs: If you are
using the Speaker-Level Inputs • on the
Subwfr, you should connect these binding-
post terminals to the front left and right
speakers, remembering to maintain polarity
by connecting the (+) terminal on the
subwoofer to the (+) terminal
on the speaker, and the (–) terminal on
the subwoofer to the (–) terminal
on the speaker. If you are not using the
Speaker-Level Inputs •, then connect
your front left and right speakers directly
to your receiver or amplifier. See pages
8 for further information on
speaker connections.
• Speaker-Level Inputs: Connect these
®
, to this input. This
binding-post terminals to the main left and
right speaker terminals of your receiver or
amplifier, if your receiver or amplifier does
not have a line-level subwoofer output.
Remember to maintain polarity by connecting
the (+) terminal on the receiver/amplifier to the
(+) terminal on the subwoofer, and
the (–) terminal on the receiver/amplifier to the
(–) terminal on the subwoofer.
ª Master Power Switch: Place this
switch in the "•" position to power-on the
subwoofer. The Subwfr will then
be either in the Standby mode or completely
on, depending on the position of the Music-
Sense On/Off Switch £.
‚ AC Power Cord: Make sure to plug this
cord into an active, unswitched electrical out-
let for proper operation of the Subwfr.
The cord should not be plugged into the
accessory outlets found on some audio
components.
