A couple of years ago I invested in Mackie's Freeplay Personal for the technically challenged. It worked just fine for it's intended purpose. Mackie also used a similar control on the ProDX and Reach with similar functionality. So out came their new Thump12/15BST and newer controls minus a bunch of useful features such as Reverb and Delay and a Feedback destroyer and missing 3.5mm input. Replaced by some unknown ready-made EQ settings. I always thought that newer versions would improve on the old but apparently not at Mackie. To top it all off the channel meters are inactive with channel mute on, REALLY. The original version had it right. So for those with this unit be sure to mute the mains before un-muting the channels unless you want a surprise. The Block diagrams are also missing mute and meter locations in the processing chain, nice job Mackie can you screw up anymore?
P.S. Their manual states "The touch sensitive faders adjust the level of each channel going to the main output. Adjustments are made by touching and dragging channel faders up and down.The input meters display the input signal level to the channel before all channel processing. In normal use, this meter should remain green with the occasional bump into the yellow zone. Lower the volume of the source if the input meter remains consistently yellow. If the input meter remains at the top of the meter display, then the signal is overloaded and clipping. Lower the volume of the source a little more." So much for manuals.
