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. To do this, we must recognize and find solutions to the unique problems, which affect the performance of electronics in the mobile environment.

At PPI, we build upon experience. We currently design and manufacture over 20 different amplifiers. Each is designed to be application specific, either in rated power, number of channels, or with integrated accessories. This large reservoir of knowledge has provided us with the innovative design solutions incorporated in the Art Series Amplifiers.

As you review this section, keep in mind that the new features found in the Art Series amplifiers directly influence their performance and, therefore, must be understood before operation and / or installation. Please take a few minutes to review the following information. The user benefit and operational parameters of the 'key' design features are detailed below.

Pulse- Width Modulated (PWM) Switching Power Supply

The voltage supplied by an automobile's electrical system will vary depending upon the number of accessories you are using. As you turn on / off various accessories (head- lights, air conditioner, rear window defroster, power windows, etc) the voltage that your car's electrical system is providing will change according to the demand. The Art Series fully regulated power supply guarantees rated spec over a wide range of voltages (11 VDC to 15 VDC).

Our PWM supply offers high-efficiency. This efficiency translates into cooler operation. The hostile environment of mobile audio presents a real problem for an amplifier to operate properly. When an amplifier is running, it develops heat It is the job of the heatsink to pull this heat away from the internal components. If the heatsink gets too hot, the amplifier will modify its operation to protect itself from damage. The amplifier's ability to maintain a proper operating temperature is oftentimes aggravated by the conditions (ambient air temperature, mounting location, playing level, duration of operation, as well as the load impedance) presented by the auto-sound environment. The Art Series PWM power supply's high-efficiency means lower operating temperatures and a higher tolerance for thermal control. The temperature protection circuit will engage at 75 degrees Celsius.

Heatsink Design

To understand why PPI created this unique heatsink design, it's important to understand what purpose a heatsink serves and how it works.

When an amplifier operates, the internal components develop heat. This heat must be transferred away from the components for them to operate properly. By securing the components to the underside of the heatsink, the process of conduction transfers
