amplifiers that provide a multitude of highly economic solutions to the problems posed by fixed installations.

Solid DYNACORD technology for fixed installations at very competitive prices was the maxims for the development of the DSA power amplifier series.

They offer a very high, stable out- put with high efficiency at a high performance level. DSA power amplifiers are therefore the ideal choice for typical fixed installation applications.

They are protected against over- heating, short circuit and both high frequencies and DC at the output. Damage to the end transistors through the feedback of electrical energy is prevented by the back EMF protective circuitry. During

a soft start, a relay delays the switching on of the power outputs.

In addition, a power-up current limiter prevents the blowing of the mains fuses. Fast audio processors continuously compare the input and output signals. In the event of any non-linearity, the processors send control signals to the limiters, which dynamically reduce the in- put gain of the power amplifier.

Input level controls on the rear panel and level and control displays on the front panel offer a high degree of user comfort, and a quick over- view of the operating state of the power amplifiers is provided by the easily read LED display with its Power, Protect, Signal Display and Limit indicators.

Aswitchable high-pass filter (HPF) (50 Hz, 18 dB/oct) can be used to suppress low frequency signals,

which otherwise could lead to satura- tion of the transformers when out- put transformers are connected. A Ground Lift switch is also provided to separate the chassis ground from the signal ground in order to eliminate ground loop hum.

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. (see pages 42-43)
