INITIAL LISTENING TEST
It’s now time to test the PL-300 subwoofer in your listening environment.
1.
Before turning your stereo system and subwoofer on, double-check all connections.
2.
Turn the volume controls on both the subwoofer and your audio receiver all the way down (fully counterclockwise)
and check that the
PHASE SWITCH
is set to 0° and
CROSSOVER FROM DIGITAL RECEIVER OR SUB SWITCH
is set to the proper setting (see Page 5, #8 and 8b below).
3.
Turn your stereo system and then subwoofer to the ON position by using the
POWER AUTO-ON/OFF SWITCH
.
(See details on Page 5, #7 regarding AUTO position after performing the “Initial Listening Test”).
4.
Confirm that the subwoofer’s green
POWER INDICATOR LED
is glowing. If it isn’t, check the power connections
between the subwoofer and the wall outlet.
5.
Play a musical selection that you are familiar with. Pick a song that has regular low bass beats. Advance the audio
receiver’s volume control up to a normal listening level. If you don’t hear sound through your main speakers, turn off
the system and check connections. Also consult the Troubleshooting Guide on pages 10 and 11.
6.
If sound is coming out of your main speakers, slowly turn the sub amp’s
VOLUME CONTROL
clockwise until you
hear noticeable additional bass. If you don’t hear bass by the time you have advanced the subwoofer’s
VOLUME CON-
TROL
halfway, turn off the system and check connections. Also consult the Troubleshooting Guide on pages 10 and 11.
7.
Adjust the sub amp’s
VOLUME CONTROL
until you are satisfied with the amount of bass (care should be taken not
to overdrive the subwoofer to the point of audible distortion). You may want to try several different movies, compact
discs or DVDs while determining how high to adjust the volume. The amount of bass will vary from disc to disc and be-
tween different types of music.
8.
Now that you have adjusted the output level of bass through the volume, it’s time to work on the quality of the bass
by experimenting with subwoofer placement in your room and adjusting the
CROSSOVER
and
PHASE SWITCHES
.
a. Subwoofer Placement
(Also See Page 3 “Placement”) – Subwoofer placement is extremely important because
it dramatically affects the bass quality. An optimally placed subwoofer is much more powerful and nice sounding than
a poorly placed one. While playing music, move the subwoofer around, in and out of corners, closer and farther from
the wall, etc. – as much as the power cord or other connections will allow to determine the best placement. You may
also want to try the “subwoofer crawl” technique found in the last paragraph of “Placement”, Page 3.
b. Crossover
– If you are connecting your subwoofer to a Dolby Digital type receiver which has a low level SUBWOOFER
or LFE output that requires a subwoofer cable for connection, you will adjust and set your subwoofer crossover through
your receiver, not by using the
CROSSOVER FREQUENCY CONTROL
on the back of the subwoofer. Set the
CROSSOVER SWITCH
to
“FROM DIGITAL RECEIVER”
and check your receiver owner’s manual for instructions
on adjusting the crossover. Make sure to go to the
“SPEAKER SET-UP”
or
“BASS MANAGEMENT”
menu and set
the subwoofer to “ON” or “YES” to enable the sub to play.
If your receiver is not digital (EX: older Dolby Pro Logic receiver), you will use the
CROSSOVER FREQUENCY CON-
TROL
on the back of your subwoofer to set your crossover from your subwoofer by setting the
CROSSOVER SWITCH
to
“FROM SUB”
. Change the
CROSSOVER FREQUENCY CONTROL
to higher and lower settings. If the crossover
frequency is set too high, you’ll start to hear low midrange (voices and instruments) through it. This will negatively
affect the stereo imaging of your main speakers. If this occurs, lower the crossover frequency setting until you hear
only bass from the subwoofer. If the crossover frequency is set too low, you simply won’t get much output from the
subwoofer. In most cases, setting the crossover to the 90Hz setting on the control yields the best results.
c. PHASE SWITCH
– Have someone change the
PHASE SWITCH
back and forth from 0º to 180º while you
sit in
the main listening position. Leave the switch in the position where bass sounds most accurate and balanced.
9.
After you are satisfied with the output of your subwoofer, you can make all your volume settings through your
receiver’s volume control. The only time you might want to re-adjust the subwoofer amp’s
VOLUME CONTROL
is when you encounter a musical selection that has abnormally low – or high – bass.
