Overall Description:
The Audica Professional MULTIzone is a zone control mixer with 4 zone outputs and 6 music inputs plus a microphone input for
paging applications. Each of the 4 zone outputs can be independently congured to provide music from one of the inputs plus the
paging microphone, with the relative levels set by front panel controls. When the microphone is used, the music is automatically
reduced in level (“ducking”) to allow for announcements to be heard clearly. Each zone output is mono but all inputs are stereo
capable (mixed to mono internally).
Zone outputs can have Audica speaker EQ applied if needed. A mute control input is provided to be linked to re control systems.
This mutes all music inputs whilst keeping the paging microphone active for safety announcements.
Remote zone control is possible via wired wall-mount control panels or an RS-232 interface.
