Mixer Amplifier – BG-2035
The TOA BG‑2035 is a versatile 35 W, 5‑input mixer amplifier designed for background music (BGM) and general‑purpose announcements. Ideal for bars, retail stores, banquet halls, and commercial spaces, it offers flexible input routing, MOH (Music‑on‑Hold) output capability, and easy configuration via rear‑mounted DIP switches. When combined with an optional booster amplifier such as the BA‑235 (35 W) or BA‑260 (60 W), the BG‑2035 enables convenient 2‑channel broadcasting.
