The Crest Audio UMA-4300 mixer amplifier provides installers and contractors a simple and efficient solution for a broad range of sound reinforcement, paging and background music applications in retail spaces, restaurants, lounges, and waiting rooms.

The UMA-4300 combines a four-input mixer with a highly efficient Class D 300-watt mono amplifier. Each of the four inputs can handle a variety of input signals, including microphone, balanced line level and mono or stereo unbalanced line sources.

Inputs 1 and 2 are electronically balanced and provide mic preamp gain controls and switched 48V phantom power for microphones. Inputs 3 and 4 support balanced and unbalanced line inputs with switch selectable Euro-style connectors or dual RCA inputs.

The UMA-4300 can drive directly a low impedance loudspeaker with its 4-ohm direct output or 25V, 70V, or 100V constant voltage loudspeaker circuit.
