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.

Power / Protect Light

POWER/PROTECT 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

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.
