DPM 4000

The DPM 4000 employs a digital audio matrix providing four inputs and outputs.

Additional matrix junctions for the integrated chime and alarm signal generators, the vocal recording/playback unit and the lock-on of the pilot tone and its evaluation are incorporated. All input signals and internally generated signals can be mixed inside the matrix and sent to the four output channels. Simple four-zone paging systems can be constructed using direct routing of output channels to dedicated zone amplifiers. More complicated systems (larger than four zones) can be constructed by using a system controlled relay matrix either pre- or post-amplifier. The DPM 4000 provides priority control of pages and other functions.

Signal generation is realized through DSP algorithms, which are extremely flexible in use, so that they can be adjusted to match nearly any possible application. Factory presets include 6 different chime signals and 17 different alarm signals. The optional digital audio memory is programmed via the PROMATRIX Designer software interface and allows for pre-recorded messages, automatic message stacking and digital alarms and chimes.

Paging consoles, telephone interfaces, stereo or monaural line level input sources and microphone level input sources can be connected via several different input modules. The DPM 4000 can be increased by using the corresponding accessories. The device has CE marking as well as UL and CSA recognition and is EN 60849 / VDE 0828 conformable in combination with the PROMATRIX® System.
