TOA A-906MK2 (60W) Modular Amplified Mixer
TOA The TOA A906MK2 amplified mixer is widely recognized as an 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 TOA 900 Series amplified mixers to perform consistently, day-in and day-out.
An Industry Leading Amplified Mixer
The TOA A900 Series are modular mixer/amplifiers designed for applications such as paging and music distribution and industrial sound systems. Engineered for high performance, the A-902MK2 (30W), A-906MK2 (60W), and A-912MK2 (120W) have a wide frequency response with very low noise and distortion. These models also feature excellent output regulation.
A900 Series mixer/amps are used in our contracting business all the time. They are perfect when you need lots of inputs, but need to be able to customize and tailor them to meet the demands of the job. This unique modular design makes the A900 Series the most versatile 70V mixer/amplifiers in the industry, period.
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. This item requires modules to in order to operate.
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. Pre-Out/Power-In jacks allow connection of external signal processing between the mixer and amplifier sections.
