Out of the box, this mixer is amazing. Lightweight compared to its analog counterparts, and it look just beautiful. I mixed some house vinyls right away, no FX. The sound quality compared to my previous mixers (djm600 and S8) is clearly superior. Hi mids are warmer and bass is well balanced.
The eq Sounds nice if boosting is requires and also cut very well (so I don't always need to activate the isolator). The filters are really nice, clean and expressive, I noticed the exponential curve is different from many mixers I've used. With some resonance, there's quite a lot of boost in the bass on the first digits of HP mode. It took me around an hour to get used to the filters and found myself a couple of times leaving a channel's level up when cueing the next track. Faders are visually more explicit in terms of channel's output.
Digital i/o's: dual USB @ 96kHz 24bit, multitrack recording, traktor scratch and so much routing flexibility! I play a duo live set consisting of 2 laptops, DJ, maschine, sub37, and guitar. We can record each set and mix it afterwards without any signal loss or d/a/d/a/d conversion. We use only one computer for the FX using the submix channel and usb session in. The output of the mixer goes to an XTA speaker manager via spdif. Again, no signal loss or extra latency. Thanks.
When I read this mixer was not analog I almost cried. But... This mixer is the perfect example of how digital CAN sound better than analog under the right circumstances, while also giving freedom to the user (where analog fails sometimes). Somehow Rane managed to keep the "analog" look and feel. The mp2015 is more than a luxury to me. It's a solution. A first in many fields of the DJ industry that need to be polished in order to respects the ears of the audience.
The headroom is amazing.
If you have the money, buy it. I didn't... Until I saw how much it would help to take full advantage of my rig and the sound system I work with. I gigged, sold the s8 and Dj tech tools helped me getting it to Mexico in less than 48 hrs :)
One more thing. It works with (one or two) iPhone/iPad via usb! Traktor will split the output into different channels with very little adjustment. Now the after party takes 1 minute to setup and sound like a "propper DJ setup". Don't take my word. Try it. I know many DJs may never like the idea, but try beatmatching two iOS devices by ear to keep it fun if you are part of the no-sync people :)
