After providing for years thousands of satisfied users with the best mixing tools, we have decided to renovate our M Series with an assortment of novelties. The new M compact mixers have been updated with improved features and repacked into a new stylish package. While keeping the superior audio quality, the full set of features and the highest number of MIC inputs in the category that have been the hallmarks of our M Series, we have added extra ‘intelligent’ functions, such as USB routing and channel COMPRESSORS. All the models feature the new PROEL 24bit PROFEX DSP, one of the finest digital eff ect of its class, providing 256 studio-grade algorithms (including mono and stereo TAP DELAY and TAP DELAY + REVERB) and a convenient LCD display.
