CONNECTION & CALIBRATION - AV RECEIVER
Connection and Initial Setup
• Ensure the main power switch is off and
connect the mains power cord.
• Set volume on your subwoofer to the
2/3 position.
• Set phase to 0°.
• Set subwoofer low pass to 200Hz
(bypass) setting. The AV receiver
will manage the crossover/low pass
frequency.
• Connect the subwoofer pre-out (SW) on
your receiver/processor to the LFE input
on your subwoofer. See “Advanced
connection methods” for alternatives.
• Switch on mains power switch.
• At this time you may wish to perform
the AV receiver’s automatic calibration
proceedure. After the automatic
proceedure is complete you may wish
to adjust your subwoofer output level to
taste. Alternatively refer to the manual
setup procedure below.
Manual Receiver Setup
Ensure subwoofer is set to ON or YES in
your receiver setup. Refer to your receiver/
processor manual for more information.
Use the default subwoofer channel level
setting on your receiver.
On your receiver select desired crossover
frequency/low pass setting. As a guide, use
the 80Hz setting.
If your speakers are small (bass driver
is smaller than 5 1/4”) use a higher
setting (100Hz,120Hz,150Hz) to send
more of the bass information to your
subwoofer. Consult your receiver
manual for further bass management
options and settings.
Manual Subwoofer Calibration
When experimenting with the subwoofer in a
home theatre installation it is also benecial
to listen to movies with extended periods
of low bass (explosions, rumbles etc). This
will allow you to evaluate the ‘impact’ and
‘depth’ of your subwoofer. It is also benecial
to select music that is familiar to you when
carrying out listening tests. As a suggestion,
play clean unprocessed recordings that use
double bass, bass guitar, cellos, organ or kick
drum that cover a wide bass spectrum.
Begin by playing the movie/music and slowly
adjust the volume dial on the subwoofer to
your desired level.
For nal tweaking of your subwoofer
level you may wish to sit in the primary
listening position and adjust the
subwoofer channel level using your
receiver’s remote control. Refer to your
receiver’s manual for more information
Set the phase dial. The correct phase setting
will produce the most bass. You may need to
listen to a variety of recordings to hear any
subtle change in bass energy. If no change
in bass energy can be heard between phase
settings, set phase to 0° default position. Re-
adjusted volume if necessary.
Advanced Connection Methods
One subwoofer - stereo connection
If your receiver has a stereo Lelf & Right
subwoofer output feature, connect both L
& R outputs to your subwoofers L & R line
inputs.
Two (or more) subwoofers
- mono connection
Using multiple subwoofers can be useful
in large or troublesome installations where
more uniform bass coverage is desired.
If your receiver has only one subwoofer
output, use a Y-cable or Y-adapter to allow
connection to multiple subwoofers.
Left and right subwoofers
- stereo connection
If your receiver has stereo line level subwoofer
outputs a left and right subwoofer may be
used to provide stereo low bass reproduction.
Connect each receiver sub output to the
corresponding subwoofer:
L sub out to the left subwoofer L(mono)input.
R sub out to right subwoofer L(mono) input.
