TOA BG-M SERIES MIXER/AMPLIFIERS
are ideal for a wide variety of
installed sound applications such as
paging, music distribution and messaging-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.
Compact Five Channel Mixer/Amplifiers for
paging, background/foreground music distribution and music/messaging-on-hold.
Proven TOA Quality and Reliability
Engineered for High Performance with wide
frequency response, very low noise and distortion, and excellent output regulation.
