Crest Audio UMA 4300 - Powered 4 Channel Mixer Amplifier

Peavey Commercial Audio U60

The Crest Audio UMA-4300 Mixer Amplifier 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 microphone preamp gain controls with 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 Mixer Amplifier can drive a low impedance loudspeaker with its 4-ohm direct output or a 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.

  • We rate PLASA as one of the best shows in the world. We’ve had a really successful event, meeting our European clients and securing new overseas contacts as well as visitors from closer to home.

  • The show was incredibly busy, I didn’t have a moment of quiet time. I’ve seen more international visitors here this year which is great. I love it!

  • We’ve been exhibiting at PLASA for around 10 years and show both competing and complementary technologies, allowing our customers to see the differences between them. No one feels they’re getting the hard sell, it works very well.

  • We were delighted that 80% of our European distribution network came to the show, and we had visitors from Korea, Hong Kong and the US. The stand was really busy and we’ve thoroughly enjoyed the show.

  • This year’s PLASA show was one of the busiest ever, and in my opinion, it was also one of the best we’ve exhibited at. All in all, it was a very positive show for us and our suppliers.

  • The show was genuinely good and there was a buzz. We certainly had a crowded stand and we hope the successful launching of new products brings the results we want. May PLASA continue for many more years.
