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.
