The BST UPA120 integrated PA amplifier boosts the audio line and delivers 120 W of power to 100 V systems. It has inputs for 3 microphones, 2 auxiliary sources, 2 line-level sources and 2 emergency signals, as well as a telephone input. Microphone input 1 provides +48 V phantom power and priority, as do the emergency inputs.

Outputs include a line output and 100 V, 70 V and 4–16 Ohm connections. The amplifier has a two-band output equalizer, multiple protection circuits and aluminum buttons. It can be mounted in a 19″, 2U rack.
