The mixer is a mixed blessing. You have to dial up parameters to make tonal adjustments, but as I remember, there is parametric eq available on each channel. There are presets for some common microphones and even one for a realist pickup. The sound is good for piano trio lounge gigs, and if you have a weekly spot, each regular group can save their settings as a scene, and pull it up on the next gig.I played through one of these systems last night for the first time: one tower, one sub, and a strange little 4 channel mixer with blue lights sticking halfway off the tower.
The crossover from the bass module to the tower sounded just a bit unconvincing to me though. A bit much on the bottom and then a bit lacking.
