The DPM 4000 represents the paging management/control unit of the ProAnnounce system incorporating all primary functions that are needed in advanced PA system installations. The DPM 4000 employs a digital audio matrix providing multiple audio I/O lines for up to 4 independent audio paths. Additional matrix junctions for the integrated gong 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. Larger 5-100 zone systems can be constructed by using the DCS400 system controlled relay matrix either pre- or post- amplifier. The DPM 4000 provides priority control of pages and other functions. The DPM 4000 provides a variety of tone generators for the generation of gong, alarm, and pre-recorded messages. Signal generation is realized through DSPalgorithms, which are extremely flexible in use, so that they can be adjusted to match nearly any possible application. Factory presets include 6 different gong signals and 17 different alarm signals.

The DRM 4000 is a rack-mixer and/or audio signal router offering eight audio inputs and two audio outputs. The inputs are divided into 4 MIC/LINE channels and four AUX channels. Each input channel can be freely assigned to either one or both output channels, offering mono two-channel operation, as well as, stereo operation modes. The DRM 4000 can be used as a pre-mixer for the DPM 4000, expanding the amount of available input channels. DRM 4000 and DPM 4000 can be linked via an RS-485 remote-interface. Priority functions, preset switching and routing are easy to configure and operate. The DRM 4000 Mixer & Router can also be used as stand-alone unit for simple sound reinforcement tasks, e.g. in a multimedia set-up, as well as for straightforward paging installations. Typical applications include the use as a mixer for sound reinforcement systems in conference rooms, multipurpose facilities, clubs, restaurants, houses of worship, etc. With the addition of the RS-232 interface card, the presets of the DRM4000 can be configured to a variety of different routing, level and page ducking settings. This greatly expands the flexibiltiy of the unit and these settings can be remotely triggered by commands sent through the DPM4000 ProAnnounce CPU.

The ProAnnounce system includes 5 different paging station models and one paging station extension of the DPC 4000 - series. All paging stations employ gooseneck microphones, 6 or 8 function keys, and a covered alarm key. An additional key as well as a keylock switch can be retrofitted. All paging stations are available with 10, 20, 30, or 50 selection keys. All models come with an LCD display (2 lines with 16 characters each). The available models are: DPC 4106 with 6 function keys DPC 4510 with 8 function keys, 10 selection eys and an alarm key DPC 4520 with 8 function keys, 20 selection keys and an alarm key DPC 4530 with 8 function keys, 30 selection keys plus an alarm key DPC 4550 includes 8 function keys, 50 selection keys and one alarm key DPC 4350 paging station extension unit provides 50 additional selection keys to any paging station above.
