Mobile Audio Electronics CONGRATULATIONS AND THANK YOU for your choice of a PrecisionPower, Inc. high performance mobile audio amplifier. PrecisionPower is proud to be a world leader specializing in the design, engineering, and manufacture of "State of the Art" mobile audio electronics. Our success is derived from the fact that we do not incorporate gadgets or passing fads into our products.
Table of Contents Important Safeguards The following list of 'Important Safeguards has been compiled to help you achieve optimum satisfaction and the highest quality performance from your new mobile audio amplifier. Please take the time to review these safeguards before operation and or installation of your new Art Series amplifier.
Glossary The following terms are used in this manual. Since they may be unfamiliar, the following definitions are provided. AM II Adaptive MOSFET II is an advanced protection circuit designed to prevent amplifier shut-off due to low load impedance. AM II optimizes output power to maintain uninterrupted operation whenever the amplifier senses a load impedance of less than two Ohms. An L. E. D.

the heat from the components to the heatsink. The heatsink, in turn, must dissipate this heat or become too hot for the internal components to operate properly. The heat can be transferred from the heatsink by three different processes: Conduction, Radiation, or Convection.
The Art Series' uniquely shaped heatsink is designed for high-efficiency cooling but improper mounting may compromise its ability to cool. When mounting the amplifier in a confined space (i.e. under), care must be taken to ensure that at least two inches of clearance is provided around the amplifier. If the amplifier is located in an area which has restricted air-flow or is totally enclosed, a fan may be used to improve air circulation.
polarity before securing each wire. If inserting larger gauge wire presents a problem, tinning the wire with solder may help. Be sure the connection is tight. The connector may be plugged into the amplifier. (Refer to Figure C) Bridging All Art Series amplifiers are capable of being bridged into a mono output due to the internal design of the amplifier. This feature permits the creation of a mono channel for a subwoofer or center channel. Also, bridging adds flexibility of operation.
TROUBLESHOOTING Adjusting Crossover Input Gains: 1. 2. 3. 4. Adjust all crossover gain controls to 0 dB, 1/2 of maximum sensitivity. Adjust all amplifier gains to 1/2 of maximum sensitivity. Turn the volume knob on the equalizer to a maximum of 3 o'clock. Increase the gain of the crossover until the onset of audible distortion. Then decrease the gain prior to the immediate point of audible distortion. This setting will minimize system background noise and prevents overloading of the crossover. 5.
