Product Overview

Equipped with 6 LINE / MIC selectable inputs, 2 LINE inputs and 1 MODULE input, the A-712 PA amplifier is designed to suit PA system applications such as announcements, BGM and broadcasting churches, large rooms and factories.

The 120 Watt A-712 Mixer / Amplifier is built with TOA's proven quality plus reliability—part of their 700 Series that brings versatile features and outstanding value for installed sound applications. Its features include 6 mic / line inputs, 2 auxiliary line inputs and a 900-Series module port. Each mic / line input includes a mic trim control and 23VDC phantom power. Speaker outputs consist of 70.7V, 25V and 4Ω. 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. The 700 Series is UL and cUL listed with competitive pricing and 5-year warranty.
