The TOA BG-235 is a versatile 35-watt mixer amplifier designed to deliver high-quality background music and clear announcements. Ideal for environments such as bars, retail stores, and banquet rooms, this unit seamlessly integrates into various audio setups. Its robust construction and thoughtful design ensure reliable performance, making it a preferred choice for both new installations and system upgrades.

Equipped with three inputs, the BG-235 offers flexibility to accommodate different audio sources.
