As much I like the sound and stability of the CQ series, there is still a lot of room for improvement.. This mixer is a good setup for speeches and small shows, and therefore to be used in more challenging envoirements. The lack of a de-esser is quite disturbing (even if it would be used in the effect slot would already help). However, a work around would be to create a bus that is externally processed and routed back into the mixer. To my surprise the routing to L-R cannot be removed? Please consider removing the default Master routing of each channel!
