Basic System Components
Shown below is a typical basic ProAnnounce equipment list of the ProAnnounce components for
a 4 zone BGM installation. This list includes a basic paging station and the ability to connect any
number of remote volume controls on the system. The design can accept up to 3 different BGM
sources to assign to any zone. The total power amplification of this design example is 400 watts.

Audio Routing Made Easy
The DPM 4000 employs a digital audio matrix providing 4 inputs and 4 outputs. 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 freely mixed inside the matrix and outputted through the 4
amplifier channels. Routing speaker lines to these amplifier channels is achieved via the relay-
matrix, which offers up to four separate audio buses simultaneously, while the DPM 4000 takes
over the management of all these signals according to their priority.
Next to connecting paging stations, the audio inputs also serve for the connection of other audio
sound sources, like microphones, mixers, CD-players, cassette decks and DAT-recorders, tuners,
etc. Several different input modules are available to optimally adjust and match signal levels and
connections.
Other additional features include the DMM4650 message manager for prerecorded
announcements, digitally controlled paging stations for extensive system control, DCS monitoring
and control system for external system control of many functions.
ProAnnounce DP Series Power Amplifiers
The DP series amplifiers includes four models, offering common features as listed below:

• Floating 70V power outputs (internally configurable to 100v, 70v or 4 Ω)
• Outputs are protected against idling and short-circuit
• Operation at 115/230 V AC and 24 V DC (emergency power supply)
• AC and battery remote on/off
• Electronically balanced inputs, transformers are optionally available.
• Input level controls
• Monitor outputs
• Temperature-controlled operation
• Pilot tone and ground fault surveillance (optionally available)
• Fault indication and fault messaging via floating READY-contact
