IINNTTRROODDUUCCTTIIOONN
The ES200P 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 ES200P 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. 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.
4. 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).
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 ES200P.
