Dynacord Professional Power Amplifiers manual 100V etc

DSA Series - Multi-Channel

Depending upon the application, each channel can be switched in- dividually even in high-impedance mode (HZ) in order to drive 70 Vrms or 100 Vrms loudspeaker lines directly without an output transformer (Direct Drive).

The power output by the DSA multi-channel power amplifiers is (along with its thermal capacity) limited only by their maximum output voltage and maximum output current, which means they can drive any load between 2 and 10 ohms with their rated maximum outputs of 500 W and 1000 W res- pectively per channel.

Acorresponding encoder-circuit is provided on the rear panel. In addition, through VLD (Variable Load Drive) in combination with a RCM-810 remote control module, it is possible to define freely which output power should be made available at which load in the frame described above in the channel in question: e.g. Channel

A = 350 W into 2.6 Ω; Channel B = 500 W into 8 Ω; Channel C = 200 W /

100V etc.

The fact that an output trans- former has been dispensed with the highly efficient Class-D power amplifiers and switching power supply yields an extremely attractive, environment- and resource sparing amplifier. For applications involving

mandatory galvanic separation of the connected loudspeakers in accordance with EN 60849 and IEC 60364 separate transformer modules are available, optionally.

Input level controls on the rear panel as well as LED meters and control indicators on the front panel offer a high degree of user comfort. It goes without saying that all protective circuits and dy- namic limiters (as is the case with in all DYNACORD power amplifiers) are available in every channel. Using the ON DELAY selector switch

on the rear panel of the power amplifier, you can set the interval of time by which the switching on process should be delayed. In Standby mode, the power consump- tion of the device is reduced to a minimum. Standby mode can be activated via IRIS-Net or the POWER REMOTE socket.

The Phoenix inputs marked IN- PUT are electronically balanced. Phoenix connectors are also provi- ded for the power outputs.

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.
