BarMIX is a unique ‘user-friendly’ zoner/mixer, enabling a choice of four stereo audio sources to be routed to each of two zones. Interlocking switches for each source ensure that there is no risk of accidentally selecting two sources for the one zone. Each switch has an associated status LED for easy at-a-glance confirmation of which program source is active, and numbered panels above each switch let you label each source. There is comprehensive 3 way EQ and an individual level control for the microphone on the front panel, as well as a Gain trim control on the rear.Front panel switches turn the microphone on for each zone, and there is also provision to connect a push-to-talk signal for priority/evac override.
