The MZU 2008 switching unit can be installed in 19” racks for selective voice/music switching in 8 audio zones, with the possibility to increase the number of zones as multiple of 8, adding other MZU 2008 in cascade. Selection of the zones in which the music is to be interrupted and an announcement transmitted is carried out from the MBT 8008 control console. Using the 8 “MUSIC” keys on the front panel, you can choose in which of the 8 audio zones to play the normal background music and in which zones no music is to be played. The system can be configured in one of the following ways: • a) the 2 inputs of the unit are driven by two amplifiers, one of which is dedicated to voice transmission and the other to music transmission. The 8 outputs of the unit drive the 8 speakers of the 8 audio zones. • b) the 2 inputs of the unit are driven by two signal preamplifiers, one of which is dedicated to voice transmission and the other to music transmission. The 8 outputs of the unit drive the 8 power amplifiers dedicated to sound diffusion in the 8 audio zones.
