AUDAC AUDPA153 3-channel Digital Power Amplifier 2 x 150 W + 450 W

The DPA series amplifi ers are digital power amplifi ers designed to meet the specializedneeds of sound contractors for Multi-Zone distributed speaker systems. They are designedin six different models of Class D power amplifi ers, divided in three different architecturesto meet the requirements for all kinds of applications.

They combine the best of all features in one single series of amplifi ers, providing anoutstanding sound quality with all the known advantages of Class D Amplifi ers. Such asthe excellent effi ciency and very low heat dissipation. And due to the complete passivelycooled entity only a minimal of maintenance is needed, while ensuring maximumreliability.

The small size of a single rack space make them very interesting for fi xed rack mount aswell as mobile applications.

The DPA73 and DPA153 are built as two channel (Stereo) amplifi ers, with an additionalchannel for powering a subwoofer cabinet. It contains an active crossover network witha frequency of 120Hz and advanced protection circuitry which protects against DCmalfunctioning, short circuit, overheating and overload.

The signal input connections are accommodated with balanced XLR connectors andsignal link through with other amplifi ers is possible using the XLR output connectors. Theoperation mode can be selected between Stereo mode, Bridge mode and Parallel mode.The output connections are accommodated with Euro-Terminal blocks.

BASIC Series - Intelligent Power

BASIC - that's meeting the tightest budgets and professional requirements
in reliability, flexibility and sound. Alone or in combination with the other
products of the Bittner portfolio.
The consequent realisation of the Bittner quality standards indicates once
more our understanding of the contracting business. It underlines our philosophy
that cost consciousness has nothing to do with giving up standards. Compromise
is a word unknown to Bittner Audio!
The incorporation of detent potentiometers, clip limiter, protection circuits for
any imaginable situation, as well as a first-class production process using only
highest-quality components made the BASIC series the choice of most contractors.

Certainly more than basic!

Solid DYNACORD technology for fixed installations at very competitive prices.
DSA power amplifiers offer a very high, stable output with high efficiency at a high performance level and are therefore the ideal choice for typical fixed installation applications. The connectivity consequently provides Phoenix type in/outs, the input level controls are located on the rear panel, also a switchable high-pass filter (50 Hz, 18 dB/oct) and a Ground Lift switch.
The POWER REMOTE connector makes the task of remote controlling the power amplifier as well as switching it on and off simple. For further remote-supervision and –control possibilities and integration into IRIS-Net networks, an optional remote control module (RCM-810) is available.
