FINEST AUDIO QUALITY FOR ALARM SOUND REINFORCEMENT

Power amplifiers of the highest quality and legendary reliability have for decades been a core element of the DYNACORD fixed installation range.

Thousands upon thousands of DPA 4000 series power amplifiers for example are proving their worth every day in countless installations throughout the globe—invariably leading in terms of performance, equipment and flexibility and always conforming to the safety regulations in force such as EN 60849, DIN VDE 0828. Naturally these power amplifiers offer ideal solutions for networking, remote supervision, remote control, emergency power and all the other imperatives of life safety projects.

The power amplifiers of the DPA 4000 series can be operated either from the mains or from an emergency power supply (e.g. battery). Power consumption is minimal in Stand By mode—as little as 2.5 mA in some cases. All the devices in the series boast outstanding audio performance, with signal-to-noise ratios, for example, in excess of 100 dB.

The DPA 4120 / DPA 4140 power amplifiers can be fitted with either the standard input module or a remote control module. Thus equipped, the amplifiers can be both controlled and supervised remotely.

Thanks to the intelligent output circuitry of the DPA 4411 and DPA 4410, the power outputs can be configured individually to deliver 4 x 100 W, 2 x 200 W or 1 x 200 W plus 2 x 100 W, according to choice.

For power amplifiers to used also in alarm sound rein- forcement systems it is necessary for them to report any malfunctions. The flawless functioning of power amplifiers in the DPA series is therefore permanently supervised.
