Product Details

TOA A-912MK2 Modular Mixer-Amplifier w/8 Ports 2U 120W

The TOA 900 Series mixer/amps are widely recognized as the industry standard in installed sound system amplification. When reliability and performance are critical—such as in paging and music distribution for airport, hospital, and industrial sound systems—you can count on the 900 Series to perform consistently, day-in and day-out.

The A-903MK2 (30W), A-906MK2 (60W) and A-912MK2 (120W) modular mixer/amplifiers are engineered for high performance with wide frequency response, very low noise and distortion, and excellent output regulation. Eight module slots allow you to easily configure custom configurations choosing from over fifty TOA plug-in modules with an extensive array of features and connector types. You can increase the input capacity by connecting a second mixer or mixer/amplifier to the rear-panel Bridge In/Out jack.

Outputs include transformer isolated 25V, 70V and 8 ohm (A-903MK2: 4 ohm) plus a direct low-impedance mode if non-transformer operation is required. Multiple paging priorities are easily configured using optional mute-type modules activated by external switch-closure or mute-send modules. Pre-Out/Power-In jacks allow connection of external signal processing between the mixer and amplifier sections. Other features include protection circuitry, auxiliary output, bass/treble controls, and remote master volume terminals. The 900 Series Mixer/Amplifiers are UL and cUL listed and carry a five year warranty.
