Adjust the crossover to accommodate your
chosen installation method.
•  LPF–(low pass filter) Select
this filter when the amplifier will
be driving woofers or
subwoofers.
•  FULL–Crossover is not active,
amplifier is in "full range"
mode.
•  HPF–(high pass filter) Select
this filter when the amplifier will
be driving full range/separate
speakers, and you want to limit
the "bass" going to these
speakers.
Crossover (X-OVER)
Level
The input level control matches the
output of your radio to the input of
the amplifier. After the installation is
complete, make sure the input level
control on the amp is turned down
all the way (counterclockwise or all the way to
the left). Play a tape or CD (make sure bass
and treble settings or EQ are flat too) and
turn the volume up slowly until you just start
to hear distortion. Now back the volume down
just a bit. On the amp, slowly turn up the input
level control (clockwise or to the right) until
you just start to hear distortion and back it
down a bit. Now your radio and amplifier
levels are matched.
Indicators and Controls
A dual status LED indicator
illuminates red or green to
indicate the status of the

Tri-mode/Three channel operation
An amplifier is usually configured for tri-mode
operation when you want to use one amplifier
to drive a pair of front speakers and
subwoofer(s). In other words, when you want
to drive a complete system with one amp.
Your Jensen amplifier is capable of tri-mode
operation.

Important
Tri-mode operation requires using "passive
crossovers". These crossovers are available
at your local retailer or install shop. Failure to
install these filters may damage your
amplifier and/or your speakers.
