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.
Power Auto, On and Off:
Auto setting - amplifier
turns on when audio is detected. On - amplifier is
always on. Off - amplifier is off.
Phase Selection:
The speaker Phase can be
inverted 180 degrees. Used with more than one
subwoofer or for abnormal room acoustics.
Low-Level Line Input:
Left and Right channel RCA
connections for low-level audio signal feed.
Speaker Level Input:
(with passthrough) Spring-
loaded terminals for up to 12 gauge speaker wire.
Allows input connections to be sourced from an
amplified speaker signal such as the Left and Right
output from an amplifier/receiver. This amplified sig-
nal is tapped off for feeding the subwoofer but the
signal is unaltered and is passed directly on to
adjoining output terminals
Speaker Level Output:
Spring-loaded terminals
accept speaker wire up to 12 gauge in size. Output
terminals feed audio to the speakers which would
otherwise be directly connected to the
amplifier/receiver’s main Left and Right outputs
(those connected to the speaker level inputs).
Power:
Molded power cord for 120V 60Hz 1.0A
power supply.
