Digital stereo mixer
The M-633D is a stereo mixer equipped with 12 input channels (6 monaural inputs and 3 stereo inputs) and 6 output channels (2 monaural outputs, 1 stereo output, and 1 stereo recording output). It has 2 monaural channel and 1 stereo channel bus lines, allowing each input signal to be assigned to each bus line individually. It features digital signal processing functions such as Automatic Resonance Control function, Feedback Suppressor function (FBS), Automatic Clipguard function (ACG), and Automatic Mute function (AUTO MUTE).
It performs advanced acoustic compensation by means of automatic processing without the use of an acoustic measuring instrument. It can be mounted in an EIA component rack (1U size).

Easy to use compact digital mixing system with feedback suppressors and auto-resonance control in a 19 "enclosure with one unit height."
6 balanced mic / line inputs for microphones or recording devices in mono via pluggable connectors and balanced TRS Jack, sensitivity individually selectable phantom power for microphones can be activated individually.
Three stereo inputs via cinch Sockets (RCA Sockets) for recording devices, individually switchable to the mixing of the left and right channel to the Mono summation.
All inputs switching and mixable can be protected on a stereo master and 2 mono sum, the edge by a cover against unauthorized access.
Optional auto-hide the three stereo inputs with signal on the mono inputs by voice activation (VOX).
Two mono outputs and a stereo output via pluggable connectors with own volume plates as well as a stereo recording connection via cinch Sockets (RCA Sockets).
Integrated automatic feedback suppressors (FBS) to increase the possible output volume for all mono channels can be activated individually. By suppressing the feedback frequencies only to the necessary level hardly any influence on the sound quality.
Anti-resonance control for improving speech intelligibility by reducing the resonance excitation in the room separately for the Mono outputs and stereo out just a measurable.
