Installation Power Amplifier
The UA 2050 is a high quality utility amplifier ideally suited for varying installation requirements. It produces 50 watts into the
4 Ohm direct output, the 70V output or the 100V output. Level controls are provided for mic/line and AUX. The AUX input is
accessible via screw terminals or RCA jacks. Bass and treble controls are functional on the total system (mic/line/AUX). When a
signal is present at the mix/line input, the AUX input is muted. This feature can be internally defeated when required. (see appendix

The unit is packaged for shelf or wall mounting convenience. The user-friendly control layout, coupled with state-of-the-art circuit
design, ensures reliable long-term operation and smooth trouble-free installation.
