Just imagine the power and versatility of the TOA Electronics A-912MK2 120W 8-Channel Modular Mixer/Amplifier, a high-quality audio solution that's become an industry standard in installed sound system amplification. This advanced mixer/amplifier is designed for situations where reliability and performance are paramount, making it an ideal choice for paging and music distribution in high-demand environments such as airports, hospitals, and industrial sound systems.
Engineered for superior performance, the A-912MK2 delivers a wide frequency response, minimal noise and distortion, and exceptional output regulation. Its modular design features eight module slots, allowing for easy customization. Choose from over fifty TOA plug-in modules, each offering a variety of features and connector types, to create a configuration that perfectly suits your audio needs.
The A-912MK2 also offers the flexibility of increasing input capacity by connecting a second mixer or mixer/amplifier to the rear-panel Bridge In/Out jack. Its versatile outputs include transformer isolated 25 V, 70 V, and 8 ohm, plus a direct low-impedance mode for non-transformer operation.
For complex paging systems, multiple priorities can be easily configured using optional mute-type modules activated by external switch-closure or mute-send modules. The Pre-Out/Power-In jacks allow for the connection of external signal processing between the mixer and amplifier sections.
Additional features of this durable mixer/amplifier include protection circuitry, an auxiliary output, bass/treble controls, and remote master volume terminals. With the TOA Electronics A-912MK2 120W 8-Channel Modular Mixer/Amplifier, you're investing in a powerful, high-quality audio solution that delivers consistent performance day in and day out.
