Great DJ Controller but the Play Buttom on the left side of the deck is not working fine

The hardware itself is great and has some bells and whistles not available with some other 'compact' DJ controllers

but i think that any pro DJ would do well with it it has all the bells and whistle, i am very happy with this controller.

If you're more of a pure hobbyist (bedroom) dj, who likes Traktor and doesn't much care about midi-programming, then the S2 Mk2 might be for you

I love this thing

I did the right thing (for me)

The most impressive thing about the denon is that I learned is that a powered controler are much better then a usb powered ones trust me ...

Good mixer, and a replacement for my ADJ VMS 4.1 that died

Serato worked pretty good (not great) with the controller connected but when using it in stand alone mode on the laptop soundcard it was unusable

Full blown Traktor install works great with low CPU load compared to Serato

The build is super high quality, especially the tables which have no wobble after a few years of decent work

Great value, top shelf sound with basic controls.

By far the best value out of all the other high end ones , of course that's my opinion

I like the 3.5mm and 1/4 TRS output for headphones

Great product great performance

Well the Denon MC4000 is great mid-range price Dj System

I think if you’re going to start somewhere when buying a controller, the Denon MC4000 is definitely worth the step up in price.

Great deal to buy from a great respectable company in the dj industry

Great deal

Love having sampler pads, hot cue pads, multiple effects per channel, and pitch bend all on the same controller, for only $400

Some of MC4000's advantages vs. S2 Mk2: #1) Build-quality: mostly metal body vs. a durable plastic body that has some "smudgy" surfaces; #2) Can access hot cue buttons 5-8 vs. not accessible; #3

Some of the S2 Mk2's advantages vs. MC4000: #1) Better (more intuitive) loop implementation using two (2) encoder/button knobs and regular buttons vs. regular buttons only; #2) Encoder/button gain and (shift-accessed) filter knobs that push-resets to null vs. basic encoder knob only

Separate, simple sampler section and slicer (alliteration, anyone?) function vs. more robust/complicated Traktor mix-deck implementation (personal preference); #11

Bought mine from the local Guitar Center, haven't had it too long yet, but I can already tell this is a great controller, perfect for the mobile DJ

The hardware itself is great and has some bells and whistles not available with some other 'compact' DJ controllers

Great Controller, not too big, gets the job done and sounds great.

Since I work with powered speakers, this controller will allow you to connect directly to them and even included an additional output for monitor

It's great, not all those over cramp expensive controller

They say big things come in small packages an denon has truly lived up to that, this item is a well built and is of Pro Grade Quality the sound to is of high standard that will please any professional thats looking for a compact portable and robust unit

The MC4000 is a pure 2-channel unit, while the DDJ-SB2 has some sort of a 4 channel control, though it’s very very limited without an actual 4 channel mixer

Unit just became defective out of nowhere
