Description
The M-900MK2 from TOA Electronics is an eight-channel modular mixer/preamplifier that delivers professional-quality audio with a wide frequency response, low noise, and low distortion for accurate reproduction. The eight module slots accept any combination of TOA plug-in modules for the ultimate in customizability, giving you the input and output options you need. The balanced, transformer-isolated terminal block output connector has a selectable impedance for a wider variety of output options.
An aux output is provided for connection to an external mixer or recording device, and a bridging in/out jack is available for input expansion or output to a recording device. A dual mute bus allows multiple levels of paging priority when used with muting modules. The master volume of the M-900MK2 can be controlled via the front panel, or remotely with an external potentiometer. Each of the inputs has an individual volume control.
