Please refer to the InstallationSection of this Manual for a list of requirements or consult your AuthorizedPPIdealer before and MoistureNever mount your Art Series amplifier in a location which would subject it to immersion or exposure to not attempt to service this amplifier yourself. Opening or removing covers will void your warranty. Forservice information, consult your Authorized PPI dealer or call PrecisionPower, customer service representatives are available Monday through Friday from 8am to 5pm MountainStandard !

4 The use of a high-powered audio system may cause hearing loss or damage. While PPIsystems are capable of "Concert level" volumes with incredible accuracy, they aredesigned for you to enjoy the subtleties created by musicians while listening atreasonable sound pressure levels.

To do this, wemust recognize and find solutions to the unique problems, which affect the performanceof electronics in the mobile , we build upon experience. We currently design and manufacture over 20different amplifiers. Each is designed to be application specific, either in rated Power ,number of channels, or with integrated accessories. This large reservoir of knowledgehas provided us with the innovative design solutions incorporated in the Art you review this section, keep in mind that the new features found in the Art Seriesamplifiers directly influence their performance and, therefore, must be understood beforeoperation and / or installation.

8 Please take a few minutes to review the followinginformation. The user benefit and operational parameters of the 'key' design features aredetailed Width Modulated (PWM) Switching Power SupplyThe voltage supplied by an automobile's electrical system will vary depending upon thenumber 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 yourcar's electrical system is providing will change according to the demand. The Art Seriesfully 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 hostile environment of mobile audio presents a real problem for an amplifier tooperate properly. When an amplifier is running, it develops heat It is the job of theheatsink to pull this heat away from the internal components.

9 If the heatsink gets too hot,the amplifier will modify its operation to protect itself from damage. The amplifier's abilityto maintain a proper operating temperature is oftentimes aggravated by the conditions(ambient air temperature, mounting location, playing level, duration of operation, as wellas the load impedance) presented by the auto-sound environment. The Art Series PWMpower supply's high-efficiency means lower operating temperatures and a highertolerance for thermal control. The temperature protection circuit will engage at 75degrees DesignTo understand why PPI created this unique heatsink design, it's important to understandwhat purpose a heatsink serves and how it an amplifier operates, the internal components develop heat. This heat must betransferred away from the components for them to operate properly.

10 The heatsink, in turn, must dissipate thisheat or become too hot for the internal components to operate properly. The heat can betransferred from the heatsink by three different processes: Conduction, Radiation, is defined as the process by which heat is transferred through matter,without transfer of the matter itself A practical example of this would be the coolingsystem in your car which circulates a liquid (matter) in order to transfer the heat awayfrom your the mobile environment, conduction is not the primary process of transferring heatfrom the heatsink. The use of a circulating liquid or gas is impractical, unless specificprovisions were made in the design of a heatsink to accomodate this type of is nothing in the vehicle which could easily be used to heatsink the heatsink.
