about this manual

To get the most from your a/d/s/ PowerPlate

TM

, we recommend that you have the installation

performed by your qualified authorized a/d/s/ dealer. If this unit is installed by your dealer, we will
extend the warranty to three years instead of the standard one year. However, if you feel that you
have the necessary skills and prefer to perform the installation yourself, this manual will guide you
through the process of installation and set-up. Please read through it completely before beginning
the installation so that you may familiarize yourself with the total procedure before you begin. If
there is anything that you do not fully understand, please consult with your a/d/s/ dealer before
attempting the installation.

keep listening, but be safe!

Sustained listening to loud music over 100dB has been shown to cause permanent hearing damage.
Systems using a/d/s/ components are capable of achieving volume levels which substantially exceed
this level. When operating your system for sustained periods at high volume, be sure to use hearing
protection to prevent long-term exposure. We want you to be able to enjoy the music for many more
years. 

features of your PowerPlate™

Remote Level Control Capability

– Can be used with accessory control AC502 to provide a

dashboard mounted rear channel subwoofer or Constant Bass level control

Digital Crossover Frequency Display

– The crossover frequency for each channel pair is displayed

on the top of the amplifier for quicker, more precise system tuning

Detachable Plug in Connectors

– High current speaker and power connectors simplify installation.

Multi-cross™   Variable Built-in Crossovers

– High-pass, Low-pass and Bandpass functions are

built-in, virtually eliminating the need for external crossover networks in even the most elaborate
systems.

Constant Bass circuit

– Signal from all input channels is summed, low-pass filtered and then made

available.

PowerPlate™  Design

– a/d/s/ original low profile, high efficiency heatsink design keeps size to a

minimum and allows mounting where space is limited.

Wide Input Sensitivity Range

– Allows connection to virtually any source unit from factory OEM

radios through low output preamps

Simultaneous Stereo and Mono

– Each channel pair may be used Stereo, Mono, Bridged or both

Stereo and Mono simultaneously. This allows an additional Mono speaker to be used with a stereo
pair for center-channel or subwoofer applications from each channel pair using passive crossovers.

Same Side Adjustments 

– The P-series PowerPlate™   makes system adjustment easy by organizing

all signal processing controls on one side of the amplifier. This layout allows convenient system
adjustment and facilitates a variety of installation possibilities when access to the controls is desired.
