Stereo pre-amplifier Apart ZONE4

Apart ZONE4

The sophisticated pre-amplifier ZONE4 allows you to control four stereo zones with just one affordable unit. In any of the 4 zones you can play music that comes from one of the 4 music sources you can connect.

There is also the possibility to assign 3 microphones to each zone where MIC1 can be a dynamic priority mic (via contact closure) or a 4-zone selective paging microphone (MICPAT-4). Each signal is assignable to any of the four output zones through dipswitches on the front and the back of the unit. Phantom power supply on MIC 1 & 2 can be activated via a dip switch.

The ZONE4 can be controlled from the front panel (with digital display), via the RS232-connector or via the IR serial. On top of that you can control the unit via the ZONE4R remote control panels. Thes control panels have a clear LED status display and buttons for music level, MIC/MIX level, source select and mute controls. Because the remote is wired with a normal CAT5 cable, it is very easy to install.

On the output side, there is a line input selector and music level control per zone. A clear digital display makes it easier to monitor the functioning of the unit. Further, there are independent MIC-MIX level control and bass-treble control per zone.

The unit is 19” format and comes standard with removable brackets. The removable metal cover (included) protects your MIC-settings.
