The TOA A-912MK2 is a high-quality 8-channel mixer power amplifier designed for professional distributed sound systems in commercial and institutional settings. Delivering 120W of output power, the A-912MK2 features eight modular input slots compatible with a wide range of TOA plug-in modules (sold separately), allowing complete customization for microphones, music sources, paging, and other audio inputs. Engineered for flexibility and reliability, it includes bass/treble tone controls, master volume, and automatic muting functions. The rugged chassis and convection cooling ensure quiet, long-term performance in schools, churches, offices, and retail environments. Ideal for integrators seeking a dependable and configurable audio solution, the A-912MK2 supports both 25V/70V distributed systems and 4-ohm speaker connections.

The TOA 900 Series 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 TOA 900 Series to perform consistently, day-in and day-out.


Features

  • High Performance

    • The A-903MK2 (30 W), A-906MK2 (60 W) and A-912MK2 (120 W) Modular Mixer/Amplifiers are engineered for high performance with wide frequency response, very low noise and distortion, and excellent output regulation.

  • Modular Design

    • 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.

  • Versatile Features

    • Outputs include transformer isolated 25 V, 70 V 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
