The TOA 900 series are widely recognized as the 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 the TOA 900 Series to perform consistently, day-in and day-out. 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. Multiple paging priorities are easily configured using optional mute-type modules activated by external switch-closure or mute send modules. Other features include bass/treble controls and remote master volume terminals.
