Design Features Input Clip Indicator The input clip indicator works in conjunction with the audio source volume knob, illuminating red when audio source reaches it’s clipping point. Input Switch (2/4 CH) Setting the 2/4 CH switch to the 2CH. position, switches the inputs to a 2-channel mode, allowing connection to only the front inputs with a 4-channel output.

Installation 1. Plan the wire routing. Keep RCA cables close together but isolated from the amplifier’s power cables and any high power auto accessories, especially electric motors. This is done to prevent coupling the noise from radiated electrical fields into the audio signal. When feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time. 2.

Operation illus.-3.1 Input Clip Indicator Setup Output Clip Indicator Setup Step 1. Step 7. Be sure to disconnect all speakers from the amplifier. Failure to comply may cause damage to connected components and/or amplifier. Adjust the Gain knob until the Output Clip Indicator illuminates to the appropriate color. Repeat for all channel levels of input. illus.-3.5 MUSIC TEST TONE * BLUE Step 2. Turn on the source unit with volume set to zero. Step 3.
Operation illus.-4.1 Adjusting Crossover Frequency Do the following individually for each channel. Placing the crossover switch in one of the HP positions sets the amplifier to the High Pass mode, enabling frequencies above the 60Hz or 80Hz cut-off point to pass. Placing the crossover switch in the AP position sets the amplifier to the All Pass mode, preventing any crossover adjustment, allowing all frequencies to pass.
