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.
Features A204 / A404 / Ax400 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.
Technical Specifications Art Series Model: A204 About your New Art Series Amplifier A404 Ax400 Continuous Power Output: (Front/Rear Output - Watts per Channel) As a world leader in the design and manufacture of high-performance mobile amplifiers, PrecisionPower, Inc.'s commitment to being: “Absolutely Start of the Art” demands that we create products that offer high reliability and superior sound quality.
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.
Exclusive use of discrete output transistors results in increased sonic transparency, outstanding dynamic range, and high-instantaneous current capability. We've designed the power bandwidth to be from 10Hz to 50,000Hz +/- 1dB. This ability to produce full power with linear frequency response well beyond the threshold of human hearing insures that the amplifier's performance over the musical spectrum will be flawless.
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 The Front and Rear channels of your (four channel) Art Series amplifier are capable of 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.
Switching is controlled via a 6 position dip switch (located through the bottom panel of the amplifier). Five of the six control switches adjust the different functions of the crossover (refer to Figure D. above). The function of each is denoted by its relative 'on / off' position It is important to note that the low-pass outputs (RCA-jacks) are always available, and the front inputs are their signal source. The position of switch 2 & 3 will determine the frequency available at this output.
