System installers looking for a professional mixer/amplifier that's versatile and easy to use will be impressed with the TOA Electronics A-706, a nine-channel, 60W amplifier/mixer for paging and background music in schools, restaurants, boardrooms, houses of worship, and other similar venues. It features six mic/line inputs with mic trim control and 23 VDC phantom power, two auxiliary inputs, and one 900 series module slot for accommodating the input module of your choice. It has outputs for 70V, 25V, and 4-ohm systems. An auxiliary output allows recording or connection of an external booster amplifier.
For paging, an auto-mute function that provides voice-activated priority muting is included. Rear-panel switches let you select which inputs activate and respond to muting. Other features include external switch-closure mute activation, channel and master volume controls, treble and bass controls, processor insert jacks, and an output level meter. Protection circuitry for overheating and short-circuiting ensure extended operation.
