The A-906MK2 (60W) Modular Mixer/Amplifier is 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 using 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 transformerisolated 25V, 70V and 8 ohm plus a direct low-impedance mode if non-transformer operation is required. Multiple paging priorities are easily configured using optional mutetype 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.
