INTRODUCTION
The PS110P 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 PS110P 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
Turns the PS110P on and off
2. Power-ON L.E.D.
Lights up to indicate that the unit is ON.
3. Input Level Switch
Speaker
Normally, the input to the subwoofer is from
a full-range speaker cabinet, or amplifier
output. (See figure 2)
Line
In this case, the input to the subwoofer is
from a line level source such as a mixer.
4. 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.
5. Ground Lift Switch
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).
6. 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 PS110P.
