Biamp Systems MXA300

The MXA300 mixer/amplifier combines a versatile 6-input mic/line mixer with 300 Watt amplifcation. Mixing functions include mic/line/tel inputs, selectable automatic & manual channel muting, channel priority assignment, remote level control, tone control, a built-in limiter, an internal chime, phantom power, MOH output, and extensive patching. The amplifier includes an output transformer, and provides rated power into direct or distributed speaker systems. The MXA Series carries a five-year warranty.
