Placement

Proper placement of your new Power Sound Audio subwoofer is
very important. Bass frequencies are non-directional, meaning
the human ear cannot locate a properly functioning subwoofer
in a typical home theater environment. While there are “rules of
thumb” regarding placement options, every room is a little differ­ent. Please remember that each time you move the subwoofer
to a different location you should recalibrate the bass levels and
experiment a little to ensure the phase setting is optimized.

Corner placement tends to work well, particularly if there are no
large openings into the room near the corner. Another popular
placement option is “nearfi eld”. Place the subwoofer as close
as possible to the key seating positions. For example, place the
subwoofer directly behind the sofa. Every room has its own set of
acoustical challenges, so experiment with different placement op­tions as much as time allows.

One method that often works well (particularly if the key seating
positions are in close proximity to one another) is to place the sub­woofer in your key seating position and then walk around the room
while a variety of bassy music and fi lm play through the system.
Mark the top 2 or 3 spots where the bass seems to sound best,
then try the subwoofer in those spots. If you purchased a ported
Power Sound Audio subwoofer (XV15 or XV30), please maintain
a minimum of three inches of clearance between the port opening
on your subwoofer and the nearest wall or obstruction.

If you are using more than one subwoofer, placing them as close
as possible (collocate) to one another will give you the maxi­mum clean output capabilities, but separating them may give you
smoother overall bass response at your seating positions. Again,
experiment as much as time allows and decide which option
sounds best to you.

GAIN CONTROL

The GAIN control is used to adjust the output level of the sub­woofer. This control should be set to a similar level as your loud­speakers in order to achieve a properly blended sound stage.
Proper calibration procedures should be used to adjust the level
of your subwoofer.

IEC AC CONNECTOR

The IEC AC CONNECTOR is where you connect the provided
power cord.

INPUTS

The subwoofer INPUTS consist of LEFT/LFE and RIGHT RCA
jacks. You only need to use the LEFT/LFE connection if you are
using a receiver or processor with an LFE or subwoofer output.
You can use a Y-connector on the subwoofer if it doesn’t power
up in AUTO mode at low levels. (Please make sure to recalibrate
if you use a Y-connector.)

PHASE CONTROL

The PHASE control is used to acoustically align the subwoofer
with the main speakers. The phase setting is variable from 0
degrees to 180 degrees.

CROSSOVER CONTROL

The CROSSOVER control is used to minimze the output of the
subwoofer above the crossover’s setting. The crossover fre­quency is variable from 40Hz to 150Hz, with an LFE mode when
turned fully clockwise. The LFE mode will bypass the subwoof­er’s internal crossover and allow all fi ltering to be performed by
your receiver or processor.

a signal is sent from your receiver or processor. If a signal is not
present, the subwoofer amplifi er is put into stand-by mode. The
subwoofer amplifi er will draw a negligible amount of current while
in stand-by.
ON = Turns on the subwoofer and leaves it on.

RECEIVER/PROCESSOR

Connecting your new subwoofer is relatively easy as long as you are
using a modern DD/DTS 5.1 or 7.1 receiver or processor. Simply connect
the subwoofer preout (RCA) on the rear panel of your receiver/processor
to the LEFT/LFE input jack on the subwoofer amplifi er. If you have a two
channel stereo system please contact Power Sound Audio to discuss the
best option to connect your new subwoofer.

SETUP PROCEDURES

RECEIVER/PROCESSOR BASS MANAGEMENT OPTIONS
Once the subwoofer is connected to your receiver or processor you
should enter the “set up” menu and set all of your speakers to “small”. If
they give you options for the crossover frequency e.g., 40hz, 60hz, 80hz,
100hz, start with 80hz. This will reroute all of the bass from your main
speakers to the subwoofer.

TURNING THE SUBWOOFER ON FOR THE FIRST TIME
Please set the GAIN to minimum, the CROSSOVER control to 150HZ/
LFE, and the PHASE to 0. Move the power selector switch to ON. The
power LED should now glow green. While listening to a bass heavy ma­terial, slowly increase the GAIN control until the overall bass levels sound
natural to you. This will give you a starting point for the GAIN control.

Typical setting is about the 1-2 o’clock position.

GAIN SETTING
Setting bass levels in your home system is usually accomplished in one
of three ways: automatically by your receiver or processor, manually with
your receiver or processors built-in test tones (or a test disc) and an SPL
meter, or by ear.

Auto-level adjustment
Your receiver or processor will automatically adjust the output level of
your subwoofer. You may need to adjust the GAIN on the subwoofer if
it is too low or too high for the receiver or processor to correct. Please
see your receiver or processor’s manual for instructions on automati­cally setting the GAIN on your subwoofer.

Setting bass levels using a SPL meter
This method tends to result in the most accurate bass volume. Simply
hold the SPL meter about ear high while sitting in your key seating
position. Activate the receiver or processor’s calibration test tones and
watch the meter as the tones move from speaker to speaker. Unless
your receiver or processor’s manual specifi es otherwise, set all speak-
ers, including the subwoofer, to the same output level.

Setting bass levels by “ear”
The best way to adjust the GAIN on your subwoofer is to use familiar
bass heavy material. Use the receiver or processor’s remote control to
manually adjust the bass levels to your preference. While it is human
nature to want to really “HEAR” the bass from your brand new sub­woofer, setting the levels to a more natural level will sound best in the
long run.

13

SETUP PROCEDURES

PHASE SETTING
The PHASE control is used to properly blend the main speakers with
the subwoofer through the crossover region. The goal is to adjust the
PHASE control so the subwoofer driver moves in unison with the main
speaker drivers through the crossover region. Think of it as a “timing
delay” for the subwoofer driver.

When experimenting with the phase setting the idea is to get the output
from the subwoofer perfectly “in time” with the output from the rest of
your speakers, primarily the left and right front speakers. If you have an
SPL meter it is easy to optimize the phase setting. Set the SPL meter in
your key seating position and play several “bassy” music tracks. While
the music is playing SLOWLY turn the phase control and watch the SPL
meter (you may need a friend for this). The highest reading is usually
indicative of the best phase setting. If you don’t have an SPL meter, you
can repeat the above process but simply use your ears to determine
when the bass seems loudest. In this scenario, sit in your key seating po­sition and have a friend SLOWLY turn the phase control. When the bass

sounds loudest to you....you have the best phase setting!

CROSSOVER SETTING
The CROSSOVER control is an adjustable low pass fi lter. Output at
frequencies above the crossover setting are minimized. This control is
typically set to the fully clockwise position (LFE) and your receiver or pro­cessor performs all of the proper fi ltering. Please contact us if you need
help adjusting the CROSSOVER control.
