1. low-pass:

Even though a subwoofer only produces “bass

notes”, the upper end of its range should be tailored

to blend well with your main speakers. The sub-

woofer should not produce any bass your main

speakers can produce. The low-pass control sets

this limit. The lowest setting (50 Hz) should be used

with large main speakers. Its middle settings should

be used with small floorstanding speakers or large

bookshelf speakers. Its highest setting should be

used with small speakers (see table on page 14).

2. On/Standby/Limit Indicator:

This indicator glows

amber

when the subwoofer is

in Standby. The subwoofer uses very little power in

this mode. It turns on rapidly whenever the main

system is used. This indicator glows

green

while the

subwoofer is On and operating. This indicator blinks

red

whenever the subwoofer reaches its full output

(1000 watts for the P1000, 500 watts for the P500).

3. phase:

The phase control compensates for placement dif-

ferences between the main speakers, the subwoofer

and your listening position. Adjusting this control

affects the relatively narrow range of notes where

the main speakers and the subwoofer “overlap”.

Adjust it for maximum output in this narrow range (not

for “best sound”). The affect this control has can be

subtle. It’s easiest to adjust when percussion is playing

a repetitive pattern.

4. volume:

This control sets the overall output level of the sub-

woofer. Adjust it with the remote control for the best

overall blend with your main speakers, after you have

set the other controls.

5. equalizer level and equalizer frequency:

Your listening room’s shape and construction (and

where you listen within it) have an unpredictable affect

on deep bass. These two controls adjust deep bass.

equalizer frequency

adjusts how deep into the bass

the subwoofer will respond. The 20 Hz setting indi-

cates the subwoofer is flat down to that frequency.

equalizer level

adjusts the output centered around the

equalizer frequency setting.

These controls let you discover the strong and deep

sonic events in your favorite program material, part of

the fun of having a great powered subwoofer.

The lower you set the equalizer frequency and the higher

you set the equalizer level, the more amplifier power you

devote to producing the deepest bass.

This, in turn, can limit the maximum overall output of

your subwoofer. If you want maximum output, setting

the

equalizer frequency

at or above 30 Hz

can give it to you.
