Crossover
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 mode 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.
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, use it 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.
Power / Protect Light
A dual status LED indicator illuminates red or green to indicate the status of the amplifier.
Green
- Power applied; ON
Red
- Protection circuit activated; STANDBY
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 amplifier 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) and turn the volume up
slowly until you just start to hear distortion. Back the volume down just a bit. On the amplifier,
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.
Bass Boost
The bass control increases the volume of the bass at 45 Hz by up to 18 db. Use very carefully!
