Engineered for modern engineering techniques every detail in this mixer has been carefully thought out to provide the very best mixing experience. For example the mono output can be configured as LR sum wedge or aux-fed sub or centre master. In Monitor mode all six auxes are available on faders with mutes inserts meters and XLR drive. The new 7x4 matrix with ambient mic capability opens up a huge number of mixing applications ncluding stereo recording zone feeds delay fill speakers and stereo in-ear monitor mixes.
