Compact 8-channel 4-bus mixer


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 fi nest 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. Designed and engineered in Italy by PROEL R&D, M mixers are hosted in an ultra-rugged stylish metal case with ABS sides, providing extended durability for a stage-proof use. As a unique feature in the category, all the models include as standard both a padded carrying bag and metal brackets for 19” rack mounting. The 8-in, 6-mic M822USB now includes a versatile USB routing section, for a complete control of the signals to and from the PC and a built-in universal power supply.
