Wiring the Input-Signal

Connections

Connect a pair of signal cables with RCA-type ends between the connectors on the amplifier and the RCA-type signal connectors on the source unit. If your radio has only speaker-level outputs, you should connect them to the speaker-level input connectors, observing proper polarity. When using the speaker-level inputs, it is not necessary to connect a wire between the “remote” terminal of the amplifier and the “remote” lead from the source unit. The speaker-level inputs will sense voltage on the speaker outputs and turn the amplifier on automatically.

If you are installing a P80.4 amplifier and your source unit has only one pair of RCA-type output connectors and a pair of speaker-level outputs, you may connect the RCA outputs to a pair of amplifier input channels (front or rear), and the speaker-level outputs to the other pair of amplifier input channels.

The BP150.1, BP300.1, BP600.1 and BP1200.1 are designed to provide con- stant bass regardless of the position of the source unit’s front-to-rear fader posi- tion. Use of this feature requires that all four inputs are connected to the source unit as labeled on the amplifier (front, rear, right and left). If your source unit has only one pair of RCA-type output connectors and a pair of speaker-level outputs, you may connect the RCA out- puts to a pair of amplifier input channels (front or rear), and the speaker level out- puts to the other pair of amplifier input channels. If nonfading bass is not impor- tant in your system, connect a pair of inputs, either speaker-level or RCA-type, to either the front or rear input connec- tors on the amplifier.

System Setup and Adjustment

Refer to figures 1–6 for location of adjustment switches and controls. Electronic Crossover and Bass Boost

P80.1, P80.4, P180.2

The electronic crossover can be selected as a 12dB/oct. high-pass filter (HPF) 12dB/oct. low-pass filter (LPF) or it

can be defeated (FLAT). The crossover frequency can be set at any frequency between 32Hz and 320Hz.

BP150.1, BP300.1, BP600.1, BP1200.1

These amplifiers are designed to drive subwoofers. Consequently, the electronic crossover is a 12dB/oct. low-pass filter which can be set at any frequency between 32Hz and 320Hz. The bass boost control will provide up to 6dB of boost at 50Hz.

Setting Input Level

Initially, turn the input-sensitivity LEVEL control to its maximum (counter-clock- wise) position. Turn on the source unit and increase the volume control until it is approximately three-quarters of maxi- mum-output level. Slowly increase the input LEVEL control (clockwise) while lis- tening to the quality of the reproduced sound. When you hear distortion on the music peaks, turn the LEVEL control back slightly. This is the maximum undistorted output level of your system. Turning the LEVEL control up farther

WILL NOT INCREASE THE OUTPUT POWER OF YOUR AMPLIFIER! It will only decrease the amount of volume- control rotation before the amp is at full- output power. It will also increase the amount of extraneous noise present in your system.
