PRACTICE SAFE SOUND™

Continuous exposure to sound pressure levels over 100dB may cause permanent hearing loss. High power automotive sound systems can generate sound pressure levels in excess of 130dB. When playing your system at high levels, please use hearing protection and avoid long term exposure.

RECORD YOUR SERIAL NUMBER AND DATE

To ensure your warranty (see back cover), please record the following information regard- ing your new amplifier.

1.RCA Input - accepts RCA input from a head unit, preamplifier, or equalizer.

2.RCA Line Output - provides easy connection to additional amplifiers.

3.Master/Slave Switch - controls whether the amplifier is a slave or master when connected in combined amplifier configurations. (Refer to the Combined Amplifiers section of this guide.)

4.Gain Control - continuous adjustment for full power output.

5.Infrasonic Switch - when On cuts off extremely low bass frequencies (below the range of human hearing, that speakers cannot effectively reproduce). The high pass filter is engaged when the infrasonic switch is On. This improves efficiency of the amplifier’s power supply, improves sound reproductive performance, and reduces chances of damaging the subwoofers.

6.High-Pass Frequency Control - adjusts the frequency of the high-pass crossover.

7.INTELLi Q Control - continuously adjusts the "Q" boost of the high-pass crossover from 0 to 10dB of boost.

8.Low-Pass Frequency Control - adjusts the upper crossover frequency of the amplifier.

9.Remote Bass Input - connects optional HP-RB1 remote bass control to control the bass level from the driver’s seat.
