TOA A-912MK2
900 Series 120W 8-Port Mixer/Amplifier with 25/70V Transformer or Low Impedance Operation

OUR PART #  A912MK2UL


The TOA A-912MK2 mixer/amplifier is a part of the 900 Series, which are widely recognized as the industry standard in installed sound system amplifiers. 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. The A-912MK2 (120W) Modular Mixer/Amplifier is engineered for high performance with wide frequency response, very low noise and distortion, and excellent output regulation.

The A-912MK2 features eight module slots that allow you to easily customize your system by 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 and 70V plus a direct 8 Ohm 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.
