INTRODUCTION
Thank you for your purchase of the H.D.A. 1003 external amplifier module. This
product provides the user with the same D-CAT amp technology that can be found in
any of the ISP Technologies active speaker systems. This system contains an internal
4
th
order crossover. Delivering 1000 watts of power. You can now get the same great
sound and performance of any of our quality speaker cabinets, out of the box and easy
to transport!
PRECAUTIONS

ADJUSTMENTS OR ADDITIONS TO THIS EQUIPMENT AT ANY TIME. DO NOT TAMPER
WITH INTERNAL ELECTRONIC COMPONENTS AT ANY TIME. FAILURE TO FOLLOW THESE
INSTRUCTIONS WILL VOID THE WARRANTY OF THIS EQUIPMENT, AND MAY CAUSE A
SHOCK HAZZARD.
THERMAL CONSIDERATIONS
This system generates heat that must be dissipated in order to maintain reliability and
insure the amplifier components stay within their operating temperature specs. To
accomplish this, the amplifier is mounted onto a heatsink that is vented on the rear of
the cabinet. Airflow is forced through the fins via a fan that turns on when needed. It
is required that the vents remain free from any obstruction to allow proper ventilation
to occur.
In addition, the amplifiers are thermally protected internally via a thermal switch, which
will attenuate the signal 40db when the temperature exceeds 120
C. When the
temperature drops below a predetermined point, full signal will be restored. ISP tests
have shown under extreme conditions that cycling will occur (40 sec. ON, 20 sec. OFF).
