Multi-zone public address system in an office or court building

The system consists of a digital mixing matrix, several different sources of audio signals, microphone desks, amplifiers, loudspeaker units, wireless microphones and wall panels.

The MAG808 matrix is responsible for distributing the audio signals within 8 independent zones. It allows inputs to be mixed and sent to any outputs. In addition, it has the ability to switch on Phantom power, parametric filters and signal equalization. The MAG808R microphone units used allow speech signals to be broadcast to a selected zone or all zones simultaneously. The MAG2107C CD/FM/SD/MP3 players and the B100S network streamer were used as music sources. In the halls, SM-300 microphones directly connected to MAG808C wall panels and audio signals from computers, used for example during multimedia presentations, were used to publicise speakers.

The system was divided into several independently operating zones: the corridor zone, where the DA4125 amplifier and DSP5040 wall-mounted or DSP5211 ceiling loudspeakers were proposed, the concert system comprising KS 12 mid-high and low-range loudspeakers together with an amplifier equipped with the TD500.4DSP DSP processor, and the conference rooms comprising the PAX-60 amplifier together with DSP5012 ceiling loudspeakers.

By default, all zones operate independently, but can be combined as required. The maximum number is eight zones.

The independently controlled stage sound system can be used for small concerts. The system can be controlled from the unit's touchscreen, or remotely from a PC or mobile app. In addition, a local wall panel has been connected to each zone, giving the possibility to adjust the volume level or select the signal source. The MAG808S panel allows direct connection of microphone and line level signals.
