Introduction
The LS200P powered subwoofer incorporates a 200 Watt amplifier. It can be used to enhance the
bottom end (bass) of a full-range speaker system and increase the overall output of the system.
The inputs to the subwoofer can accept a single source either from a speaker/amplifier output or
a line level output from a pre-amp or mixer.
The LS200P
also has a built in limiter and thermal
protection
that make this product smooth
and robust at high power levels. The internal limiter and the internal protection are factory set to
maximize performance.

1. Power Switch
2. Volume
Set the volume control to a desired level as
music is being played through the unit.
A setting of 0 dB on the SUBWOOFER LEVEL
control is the correct starting point when setting
up a sound system. From there the sound can
be adjusted for best sound. The 0 dB mark refers
to the setting that will give full power when the
line input is used and the input signal is at a
level of +4 dBV. This also is the setting to give a
sensitivity of 2.83 Vrms (1 watt 8-ohms) for 100
dB spl when set for speaker level input. With
a typical full range companion speaker this
will give flat response. In either line or speaker
operation it will usually be desireable to set the
control at +3 to +6 to give some bass boost
at low power levels. At levels approaching
full power the built-in limiter will automatically
reduce the gain to prevent over powering the
subwoofer. Operation with settings significantly
above +12 may clip the circuitry in the
subwoofer reducing the dynamics of the music.
Setting the subwoofer gain above +12 is only
appropiate at low operating levels.
3. Ground Lift
If a hum, or buzz is detected from the
subwoofer, try setting the switch to the GND
LIFT position (OUT position). The switch should
otherwise be left in the GND (IN position).
4. Input Level Switch
Speaker
Normally, the input to the subwoofer is
from a full-range speaker cabinet, or amplifier
output. (See figure 2.0)
Line
In this case, the input to the subwoofer
is from a line level source such as a mixer.
5. Input Jacks
The two inputs are balanced 1/4 inch parallel
jacks and can be connected as shown
in figures 2 and 3, on the following page.
Please note that there is no effect to the
performance of the full-range speaker if it is
used to supply a music signal to the LS200P.
