Speaker Level Input:
(with passthrough) Binding
post terminals will accept up to 12 gauge speaker
wire or banana jacks. Allows input connections to
be sourced from an amplified speaker signal such
as the Left and Right output from an
amplifier/receiver. This amplified signal is tapped
off for feeding the subwoofer but the signal is unal-
tered and is passed directly on to adjoining output
terminals.
External Heat Sink:
Provides heat dissipation for
the subwoofer’s internal amplifier. Do not cover or
place against another object as this may impair its
performance.
Volume Level Adjustment:
Increase or decrease
the output level relative to the incoming signal.
Crossover:
Provides active filtering of the incoming
signal to allow only lower frequencies to be ampli-
fied. Adjustment range from 60Hz to 160Hz.
Phase Selection:
The speaker Phase can be vari-
ably adjusted up to 180 degrees. Used with more
than one subwoofer or for abnormal room
acoustics.
Power Auto, On and Off:
Auto setting - amplifier
turns on when audio is detected. On - amplifier is
always on. Off - amplifier is off.
Low-Level Line Input:
Left and Right channel RCA
connections for low-level audio signal feed.
LFE Input:
RCA connection for pre-filtered low level
signals from a processor such as home theater
receiver.
Power:
Molded power cord for 120V 60Hz 4.0A
power supply.
Speaker Level Output:
Binding post terminals
accept banana jacks or speaker wire up to 12
gauge in size. Output terminals feed audio to the
speakers which would otherwise be directly con-
nected to the amplifier/receiver’s main Left and
Right outputs (those connected to the speaker level
inputs).
