UMA™ 4300

Description:

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

The UMA 4300 combines a four-input mixer with a high-efficiency 300 Watt Class D mono amplifier. Each of the four inputs can handle a variety of input signals, including microphone, balanced line level, and unbalanced mono or stereo line sources. The UMA 4300 provides a simple paging solution with priority mute level detection controls on input 1. Inputs 1 and 2 are electronically balanced and provide microphone preamplifier gain controls and 48V switched phantom power for microphones. Inputs 3 and 4 support balanced and unbalanced line inputs with switch-selectable European-style connectors or dual RCA inputs.

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

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