USER NOTE:
For normal operation connect the PS210P just like an ordinary speaker, along
with the Full-Range speakers and set the Input Level switch to SPEAKER. If the
audio source does not have a ground pin on the AC cord, the Input Ground
switch must be set to GROUND (GND). The PS210P may be plugged in before or after
the Full-Range speakers. Use the Left and Right Inputs when using a single PS210P
in a stereo system. Use either the Left or the Right inputs when using separate
PS210P's for each side (or when used in a Mono system). The PS210P does not alter
the signal to the Full-Range speakers, and will not draw any power from the host
amplifier driving them. Please note that an external crossover is not necessary.
Refer to Owner's Manual for other Modes of Operation.

INTRODUCTION
The Pulse Powered Subwoofer PS210P is a subwoofer with a built-in amplifier designed to drive the unit all
in one easy-to-connect package. It is intended to be used to extend the bass of a typical sound system with
a minimum of complication and hence is intended primarily to operate with speaker level signals.
FEATURES
1. INPUT LEVEL SWITCH
A switch is provided to switch input levels
between Speaker level and Line level. Line level
operation is only appropriate when used with an
active crossover with a crossover frequency of
125 Hz or lower. All other modes of operation
should be done at speaker level with the level
switch set to SPEAKER.
2. INPUT GROUND SWITCH
The PS210P expects the source feeding it to be
grounded. A system comprised entirely of
ungrounded equipment may cause the PS210P to
hum or buzz. If you have a buzz or hum
problem, try setting the switch to the grounded
position (GND). The switch should otherwise be
left in the ungrounded position (GND LIFT). Do
not use the grounded position with an amplifier
operating in bridged mode or when the sleeve of
the input signal is live.
3. ACTIVE LIMITING EQUALIZATION
The PS210P contains circuitry designed to achieve
maximum utilization of both the amplifier and the
speakers without distorting audibly. At low to
moderate power levels the very low frequency
sounds are electronically boosted to extend the
response to 45 Hz. As the sound level is increased
the PS210P reduces the boost and may even cut
the 45 to 60 Hz response in order to achieve
adequate output without over excursion of the
speakers or running out of amplifier power. At
extremely loud levels most of the PS210P's output
is concentrated around 90 Hz where the bass is

most audible. As the input signal is increased the
PS210P reduces its sensitivity to prevent distortion.
At high power levels when the limiter is
operating, increasing the subwoofer level control
will not increase the output. Do not increase
setting while operating at high levels.
The limiter circuitry operates to prevent over
excursion of the speakers, over heating of the
voice coil and excessive clipping of the amplifier.
4. SUBWOOFER LEVEL CONTROL
The subwoofer level control on the rear panel of
the PS210P is intended to adjust the amount of
bass added to the sound system by the PS210P.
This adjusts for the relative sensitivity of the
companion full range speakers and the desired
system frequency response. This control should
be set by listening while operating at a medium
level and then not changed. It is not possible to
set this control properly at high levels since the
limiter is determining the output level.
5. MULTIPLE PS210Ps
As well as accommodating the full range speakers
the PARALLEL THRU jacks allow many PS210Ps
to be connected in a string (or otherwise in
parallel). There is no practical limit to the number
of PS210Ps that may be connected together.
