The MZ-280Q features four individual 280 Watt RMS Class D power amplifiers, each configurable to run 70/100 Volt or at minimum 4 Ohm impedance. Each amplifier powers a zone, which all have front panel controls for volume, two band eq and source select, found on the front panel. There are five flexible input channels, each with a front panel mounted gain trim control. Dual combi microphone inputs allow two individual mics to be connected simultaneously both with auto or manual priority modes. Built in a full size 1U rack case, the unit is extremely robust with easily operable controls. Front ‘scribble’ strips allow the installer to easily identify each zone and input identification. The perfect installation amplifier for retail, leisure, café, bars and halls.
