The TOA BG-220 20W Three-Input Mixer Amplifier mixes background music and announcements for commercial audio systems. Designed for bars, retail stores, and banquet rooms, it delivers 20W rated output, supports three inputs, and provides 4 ohm, 25V, and 70V speaker outputs.

This compact TOA mixer amplifier is built for installers who need a 20W commercial amplifier for paging, music, and zone expansion. Its removable terminal blocks speed up installation, while rear DIP switches simplify configuration. Use it to buy a three-input mixer amplifier for background music systems or general announcement applications.

The BG-220 supports 2-channel broadcast capability through its MOH/ZONE 2 output when paired with compatible BA-200 Series booster amplifiers.
