Awesome addition to my studio

This piece replaced my Mackie 24x8x2 that I bought from Sweetwater, in 1997. First thing I noticed was the headroom and separation. The noise floor is much lower than my Mackie, of course. Since I use a DAW and a Mackie Controller and Extender, another full blown mixer wasn't required. But I still wanted pan and volume control and this unit has both. I'm still experimenting with both the transformer and transformerless outputs and it's nice to have both. Buy it and be blown away.

BEST SUMMING MIXER FOR THE PRICE

Let me start out by stating that I've used only the Roll Systems Passive Summing Mixer (disaster), and the D-Box (pretty transparent). First time I hooked this up, the Op Amps were not connected THANK YOU FEDEX - always insure packages, package them well, etc.. Anyway I got it fixed with some help from friends (the Op Amps were disconnected....reconnected them) and hooked the DB-25 cables up hooked the MIX L/R up via my snake cable, created a sum out 3/4, sum out 5/6, etc., in my PT HD 11 I/O menu, and then made the stereo track for summing. I immediately recorded it and the sound was out of this world. These Op Amps are special. Very colorful, saturated, and the best and funnest part were the pan knobs and the gain knobs as well as the stereo link connecting channels 5 and 6 for example you can go mono or stereo you literally have so much at your finger tips with lovely lighting (okay not that cool but still neat). I don't know what else to say other than this has been an experience I will continue to grow with and I highly recommend if your budget is around this price - GET IT. This piece of gear without any doubt will revolutionize your audio quality and sonic integrity more than anything I've come across. If you crave those console/analog sounds BY ALL MEANS GET A TONELUX!
