Design and operating principle
The unit is a multi-zone PA player-controller designed to manage the routing of audio programs to the zones of a public address and background music system. It comprises a built-in media player, a priority circuit and zone switching: the output of two external PA amplifiers is fed to amplifier inputs 1 and 2 and distributed across six zones.
Signal sources can be the built-in player (USB / FM / Bluetooth), the microphone input and the line input. The signal is sent to the external amplifier; the amplified signal returns to the unit and is switched to the selected zones. Operation is handled from the front panel: zone selection, manual/auto mode and the schedule menu on the display.
