The Crest Audio® UA™-2050 utility amplifier provides installers and contractors a cost effective, efficient and inconspicuous solution for background music and paging applications. The UA-2050’s small form factor is perfect for mounting under the counters, on the closet walls or on the shelves of retail spaces, restaurants and offices. Despite its convenient size, the UA-2050’s features, versatility and power are ideal for any application where background music and paging are required.

The UA-2050 combines a pair of inputs with an efficient Class D 50-watt mono power amplifier capable of driving a direct low-impedance output or 70V or 100V constant voltage output. The amplifier features bass and treble controls to allow equalization for any installation location.

The UA-2050’s two inputs provide simple and trouble-free configuration for quick installation and easy operation. Input 1 is a balanced microphone or line input via screw terminal barrier strip connectors. Input 2 is a line level input via dual RCA connectors or unbalanced screw terminals. The level sensing on Input 1 mutes Input 2 whenever a microphone signal exceeds the adjustable level threshold. The level sensing function can also be defeated to prevent muting of Input 2.

The UA-2050 is housed in a conveniently-sized steel chassis to allow it to be mounted in any location, and has a voltage selector switch for 120V or 240VAC operation.
