Left and Right Line-Level Inputs:
These inputs accept full-range, line-level signals from
an external source. The full-range Left and Right input
signals are mixed together by the amplifi er’s input
circuitry and applied to a lowpass fi lter. The lowpass fi lter
removes unwanted mid- & high-frequency components
from the signal and delivers low-frequency audio to the
The primary purpose of this input is to simplify wiring
to the sub and aid in daisy chaining multiple subs. This
input accepts a full-range, line-level signal from an
external source. The signal is buffered and passed
directly to the Sub Output without any processing then
goes to the local input circuitry for conditioning by
the low-frequency fi lter circuits in the same manor as
the Left and Right Inputs.
The primary purpose of this output is to aid in
daisy chaining multiple subs. This signal is a
buffered output of the Left, Right or Sub inputs.
The full-range signals from the line-level inputs are
presented at this output, no signal conditioning,
or fi ltering is done to this signal. The level
control does not effect the gain of this output.
This amplifi er is designed to operate from a
115–230VAC 50-60Hz power source capable of
delivering up to 10A of current.
Refer to the markings on the amplifi er to
determine the proper operating voltage for the model
This is a 16A/125vac, 10A/250vac double pole
single throw power switch that complete disconnects
the AC Mains from the amplifi er circuitry.

Specialized Setup Information
For fully extended bass response to 20Hz, use Left
and/or Right or the Sub Input.
Drive both the Left and Right Inputs from separate
This is the amplifi er’s high current output, used to
drive a speaker with 4-ohm or greater impedance.
The sub Input and the Left & Right Inputs are the
same; all three signals are processed by the
amplifi er’s level control, crossover, and phase
controls of the amplifi er.
The Sub Output is a buffered output of the summed
Left & Right and Sub Inputs. Level, Crossover, and
Phase control have no effect on Sub output level.
The buffered Sub Out allows you to daisy chain
as many amplifi ers as you want without loss of
