The M-900MK2 Mixer/Pre-amplifier is engineered for high performance with wide frequency response, very low noise and distortion, and excellent output regulation. Eight module slots allows you to easily configure custom configurations using TOA plug-in modules with an extensive array of features and connector types. With the rear-panel Bridge In/Out jack, you can increase the input capacity by connecting a second mixer or mixer/amplifier. Outputs include a balanced, transformer-isolated, line-level output for connection to an external amplifier and an unbalanced auxiliary output.
