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. The UMA 4300 provides a simple paging solution with priority mute level sensing controls on input 1. Inputs 1 and 2 are electronically balanced and provide mic pre-amp 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.

The UMA 4300 is housed in a 2U rack mount chassis and has a voltage selector switch for 120V or 240VAC operation.
