The ZONE4 is a high grade designed and produced pre-amplifier : perfect for multi-use and multi-zone applications. It allows the user to control 4 stereo zones with just one affordable unit. ZONE4 makes it possible to assign 3 microphones and 4 stereo line inputs to any of four output zones. This unit pro-use, and can be digitally controlled by RS-232, through a remote control panel and IR-serial. The unit is 19” format and comes standard with removable brackets. The removable metal cover (included) protects MIC-settings. It is possible to connect 3 mono MIC/LINE inputs via a Euroblock connector (= easy installing). Every MIC input is assignable to any of the 4 zones, and there is phantom power selectable on MIC 2 and 3. Each signal is assignable to any of the four output zones through dipswitches on the front and the back of the unit. There is a priority input for paging or emergency. To make things even easier, our four zone paging microphone MICPAT-4 is especially designed to work with zone 4. Just press any of the buttons on the microphone’s base to put a paging call out to one of the four zones. MIC-input 1 mutes the line input, MIC 2 inputs 2 and 3 mix with the line input. 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. There is a versatile and affordable remote control for this unit. ZONE4R is sophisticated, stylish and yet easy to control. It has 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.
