The AA120M from Atlas is a versatile mixer/amplifier that's great for paging or background music in retail spaces or businesses, priority volume control applications, commercial PA, and more. The six-input mixer offers a wealth of useful features, such as true three-zone matrixing, bridge in and out with built-in relay control, a 24VDC output with relay sync to the mute bus, and more.
The AA120M has four mic/line phoenix-type inputs, and a stereo RCA input. The sixth input is a module slot, which allows you to customize the amplifier to meet your needs. Outputs consist of a screw terminal loudspeaker strip, RCA outputs for line, tape, and pre, and a phoenix connector for zone 2/3 output.
The front panel offers an intuitive interface, with a master gain control, individual gain controls for each input, and bass and treble controls. The rear panel features ten DIP switches for controlling the low cut filter, VCA control, phantom power, relay, mic/line selection, and more. Zone 2 and 3 level controls are also available for the inputs. Each input has vox mute selector switches that allow you to select send, receive, or off. A 120VAC power outlet is provided that allows you to connect additional equipment, such as a work lamp.
