TOA BG-M SERIES MIXER/AMPLIFIERS are ideal for a wide variety of installed sound applications such as paging, music distribution and mes- saging-on-hold. Engineered with unmatched TOA quality and reliability, the versatile BG-M Series is loaded with useful features and an essential tool for any sound system designer or contractor.

The BG-M Series Mixer/Amplifiers are comprised of four models, BG-1015 (15 W), BG-1030 (30 W), BG-1060 (60 W) and BG-1120 (120 W), all built with a compact, space-saving chassis design. Input channels include: microphone and telephone paging inputs, program and auxiliary music inputs plus a flexible module slot compatible with industrystandard TOA 900 Series modules which have an extensive array of features and connector types. Outputs include transformer-isolated 25 V, 70 V and 4 ohm, balanced, line-level Music-On-Hold plus a 1 watt output for driving an additional 8 ohm speaker zone.

Muting modes include an Auto-Mute function for voice-activated paging override of the BGM channels without interrupting the MOH output. External mute terminals allow you to activate the mute function with an external switch-closure.

Other features include bass/treble controls, insert jacks and Signal, Clip, and Power indicators. Built-in protection circuitry and an AC mains circuit breaker ensure long life and outstanding reliability.

Accessories include optional rackmount kits and volume control security knobs to protect settings.

The BG-M Series is UL and cUL listed with competitive pricing and a fiveyear warranty.
