Description
The W-912A from TOA Electronics is an in-wall, 120 watt, six-channel modular mixer/amplifier. A variety of available input, output, and control modules make the W-912A useful for a variety of applications, including paging and background music. It offers a wide frequency response with low noise and distortion for clear, professional audio.
Processing features of the W-912A include a nine-band equalizer, high and low pass filters, and a compressor. A muting function allows input priority override for paging. Protection circuitry for overheating, DC, and overload prevent damage to the system. On power-up, the outputs are momentarily disconnected to prevent damage to speakers. The unit can be flush or surface mounted, and expandability up to eight channels is possible with the optional WE-2.
