INTRODUCTION

General

Thank you for purchasing a D.A.S. power
amplifier. It has been built with the most advanced
modular technology, and has been designed
through the use of computer-aided design for both
the electronic and mechanical parts.

Features

•
Dual balanced XLR and Jack 6.35mm (1/4")
input connectors .
•
Output terminal connections.
•
Variable speed back-to-front fan cooling.
•
Front located volume controls.
•
Overload protection.
•
Short-circuit protection.
•
Independent thermal protection
channel.
•
Turn on current limiter.
•
Turn on delay.
• Open circuit protection.
•
Stable into reactive or mismatched loads.
•
Ultrasonic and RF protection.
•
Modular technology: Easy to replace modules.
•
Class AB.
•
Stereo, parallel and bridge operation modes.
•
Power On, Clip and Protection LED indicators
for each channel.

A channel's protection may be triggered by:
Overheating sensed at any part of a
channel. When the amplifier has cooled down,
the channel's output will be connected and
operation will resume. The control circuit has
some degree of built-in hysterisis to avoid turn-
on and off oscillations.
Presence of DC at a channel's output.
Since it may severely damage speakers, the
amplifier will deactivate the output in the event
DC levels are detected. Once DC is no longer
present, the PROTECTION LED will turn off
and output is reactivated.
When the amplifier is switched on, the
output is also deactivated for a few seconds to
prevent dangerous transients from damaging
the speakers, and the Safeguard LED is on
until the amplifier is ready for use.
