MA 4120 MKII 480W 4 Zone Mixer Amplifier

These 4 Zone Mixer Amplifiers are ideal for systems where multiple zones are required. Designed for use in schools, churches, entertainment venues or commercial buildings, they offer multi zone audio routing coupled with four independent amplifiers. Theyhave five input channels, each with selectable independent output routing, input gain, treble, bass and volume controls. Four output zones each feature LED VU indicators, monitor selection and volume controls with outputs for line level, low impedance (4-8O) and constant voltage speaker systems (25V, 75V and 100V). The on-board monitor facility, selectable for each zone output features both a line level audio and 1W 8Ω loudspeaker output suitable for driving a loudspeaker local to the zone mixer.
