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 dam-
age. 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™
Transient Perfect
TM
MOSFET Power Supply – The heart of the P-series, this supply frees the
PowerPlate
TM
from the constraints of common pwm (pulse width modulated) supplies. The advan-
tages are: extremely fast overload recovery time, low output
mpedance for superior damping, and stability during voltage fluctuations for reliable performance
in the harsh automotive environment.
Remote Subwoofer Control Capability – Can be used with accessory control AC502 to provide
a dashboard mounted subwoofer or rear channel level control
Detachable Plug in Connectors – High current speaker and power connectors
simplify installation.
Multi-cross
TM
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.
PowerPlate
TM
Design – a/d/s/ original low profile, high efficiency heatsink design keeps size mini-
mum 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.
Same Side Adjustments – The P-series PowerPlate
TM
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.
