The X1800 is a great mixer. Familiar to any user coming over from the competitors units but filled with extras that enhance the experience and ease of use. Especially when used in line with the sc5000 or sc5000M. However as mentioned in my SC5000 review, Denon are letting themselves down with the build quality of their units. Since changing my rider less than 2 months ago i have had a replacement X1800 and 3 replacement SC5000s. Denons customer service has been brilliant but that amount of unreliability is no good in the DJ booth

This mixer is outstanding, the flexibility of it opens up so many choices for djs. Sound quality is superb.

This mixer is a beast......the sound and performance is immense. Even if you can't afford or don't want to invest in the Prime Players this mixer is worth a serious look to purchase on its own. Everyone needs to remove the blinkers which they have on regarding the competition....THE BAR HAS BEEN RAISED!!!

Great mixer. Great service from djkit. Love the mixer hooked up to the sc5000 decks.

I already tested it before my purchase and I'm pretty much in love with it. It has lots of value for a more than correct price. The 2 usb connectors really makes my life more easy, now I'm able to connect both my Traktor DJ laptop and my Live video stream computer directly to the mixer. I even connected my MOTU audio interface for using Ableton Live from my laptop simultaeniously. I was however a bit disapointed about two issues from the newly bought X11800 Prime Mixer I did not noticed tesing the one from a friend. 1. there are several dust particles (I didn't counted them but at I noticed least 5 of them) underneith the shiny black stripes on the left and right side of the mixer. 2. The dot on top of the potmeters of all channels it not in the middle but slightly to the right. Both issues are kind of a lack of quality control as I see it. Especialy the dot is kind of confusing when mixing. And the dust particles will probably lead to paint spring off after some use.

1st class mixer , very impressed with the sound quality on this and the amount of individual effects, not used the sound card USB input yet , as using the decks with it , its built like a tank and very well laid out loads of options to customise if required , but works straight out of the box, got it networked to the Denon decks and love the on Air indicators when using the sliders and the colour coded decks to cue buttons.
