A-700 Series A-724 Mixer/Amplifier- 240 W
TOA 700 Series Mixer/Amplifiers offer versatile features and outstanding value for installed sound applications such as boardrooms, educational facilities, houses of worship and many others. The 700 Series model lineup includes the A-706 (60 W), A-712 (120 W), and A-724 (240 W); 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.
Optional accessories include the MB-25B rack-mount kit and YA-920 volume control security knob. The 700 Series is UL and cUL listed with competitive pricing and a five-year warranty.
