The A-724 from TOA Electronics is a nine-channel, 240 watt amplifier/mixer for paging and background music in schools, restaurants, board rooms, houses of worship, and other similar venues. It features six mic/line inputs with mic trim control and 23VDC phantom power, two auxiliary inputs, and one 900 series module slot for accommodating the input module of your choice. It has outputs for 70.7 volt, 25 volt, 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.
The Toa A-724 offers versatile features and outstanding value for installed sound applications such as boardrooms, educational facilities, houses of worship and many others. all manufactured with proven TOA quality and reliability.
Features include six mic/line inputs, two auxiliary line inputs and a 900 Series module port. Each mic/line input includes a mic trim control and 23 VDC phantom power. Speaker outputs consist of 70.7 V, 25 V and 4 ohm. An auxiliary line output can be used for recording or connection to an external booster amplifier.
An Auto-Mute function provides voice-activated priority override. You can assign inputs to activate or respond to the muting function with rear panel DIP switches. Muting can also be activated with an external switch-closure. Other features include channel and master volume controls, bass/treble, processor insert jacks and output level meter. Master volume and power on/off can also be controlled remotely. Short-circuit and thermal protection circuitry ensures extended operation.
