LPF

•LPF –(low pass filter) only bass tones go to speakers. Use with woofers or subwoofer.

•FULL –all tones go to speakers. Use with full-range speakers.

•HPF –(high pass filter) blocks very low tones from the speakers. Use with 6" or smaller speakers.

Use LPF and HPF to adjust from 50 to 250Hz.

Input Level Control

LEVEL	The input level control
	matches the output of your
	radio to the input of the
MIN MAX MIN MAX	amplifier. After the installa-
	tion 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.

When using your Jensen amplifier to run a subwoofer and two full-

	HPF	range speakers (known
		as Tri-mode or three
		channel operation) you
50 250		50 250 will need to purchase
		separate high and low

pass crossovers from your local retailer. A pair of high pass crossovers for your full range speakers and a low pass filter for the subwoofer. This will allow the amplifier to work properly when installing it in Tri-mode. Failure to install these filters may damage your amplifier and/or your speakers.
