It switches between 4 stereo line inputs and a balanced mic input with priority and phantom power, and it can be controlled from a browser, AUDAC Touch, RS-232, TCP\/IP or RS-485. Optional MWX45 wall controllers and WMI wall input units give staff local control and sources. It runs from the included PSD241 24 V adapter and is passively cooled in AUDAC's S-box enclosure. Optional MBS1xx brackets mount it out of sight.
