introduction
Although it may be hard to remember, back in the 1970’s, car audio as we now know it didn’t
really exist. Sure, music lovers could buy a cassette or 8-track tape deck and some 6" x 9"
three-way speakers. Advanced stereo buffs might even add a "power-booster" to increase output
to as much as 12 watts RMS! But none of this really delivered the power to cut through road
noise with sound quality that compared with the best home audio. Not until 1979 that is, when
a/d/s/ introduced the revolutionary PowerPlate
TM
P100 amplifier and 300i 2-way plate
loudspeakers. Aesthetically, the P100 introduced the low profile design which has been an a/d/s/
trademark to this day. Technologically, the P100 combined a high efficiency switching power
supply with a state-of-the-art, discrete high-current stereo power amplifier. For the first time, a car
audio system existed with the musical integrity and dynamic range that made you want to take
long drives to nowhere, just to listen to the music. High quality car audio was born, and the
original a/d/s/ PowerPlate
TM
P100 made it happen.
The latest improvements to the PowerPlate
TM
line-up include increased heatsink area to facilitate
higher power output, and fully balanced high-level inputs compatible with any source. The
amplifier you have purchased is an enhancement of the respected P-series multichannel amplifiers.
In this version, we have improved upon the already acclaimed sound quality by addressing internal
details, and upgrading selected components to incorporate the latest technology which may not
have been available when the P-series was originally designed. Selected low-noise, high-speed
Burr-Brown op amps are used in critical circuits. Class-A biasing is used throughout the
voltage-gain and active crossover stages. Numerous modifications and "tweaks" were also
performed which improve the power supply dynamics and reduce noise. These changes improve
transparency and dynamic linearity, resulting in a smoother and more detailed top-end, tighter
bass, more explosive dynamic contrasts, and virtually holographic imaging. Left intact are the
P-series unequalled flexibility, high efficiency and superb reliability. These, along with multi-channel
design, are fundamental in the a/d/s/ approach to systems engineering, which makes achieving
true high fidelity reproduction simple and predictable in any installation.

There are two things you must do to ensure trouble free service in the event you need warranty repairs.
1. Keep your original sales receipt in a safe place. A copy of the receipt will be required to obtain
warranty service.
2. Be sure your retail dealer has written the date, model number and serial number (if applicable) of the
