Crest Audio
Legendary for its powerful and reliable touring-class sound reinforcement tools, Crest Audio is a global leader in designing and manufacturing power amplifiers for live, commercial and networked sound systems, and a complete line of mixing consoles for live and installed audio markets.
Crest Audio burst onto the audio scene in the late 1970s with the singular goal of advancing live sound through bulletproof engineering. The low noise, high headroom and live sound features Crest Audio was able to pack into its mixers set a new industry standard, and they immediately became indispensable on the touring circuit. they soon found ways to incorporate more punch into everything from preamps to loudspeakers and everything on the rack in between.
Crest is a company after Peavey’s own heart, so it made perfect sense when Peavey acquired Crest in 1999. Still sold under the strong Crest Audio name, the product line continues to deliver more features and more reliability than ever
The Crest Audio UMA 4300 4 Channel Mixer Amplifier combines a four-input mixer with a highly efficient Class D 300 Watts 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.
