The Pioneer DJM-850 is one of the best sounding DJ mixers I’ve used and it will definitely live up to the club-standard reputation in every way. The sound was full and vibrant and it just felt like everything was being played back as the studio production teams intended.
In conclusion, the Pioneer DJM-850 is one of the best four channel DJ mixers on the market today. The build quality and sound quality are basically second to none. The DJM-850 is Traktor Scratch Certified and can work with up to four external DVS-timecode decks and Traktor Pro right out of the box. There is a very extensive effects section with the addition of the cool Sound Color Effects and solid EQ controls.
The crossfader is scratch-worthy and the linefaders are perfect for mixing. To top it all off, there are a bunch of input and output options to suit almost every DJ’s needs. The only real negative I could find with this mixer would apply only to Pioneer CDJ-900 and CDJ-2000 users who use the Rekordbox software to manage their music.
The DJM-850 is not compatible with the Pioneer Rekordbox meaning that it cannot sync the BPM and other information with the digital decks. Other than this minor gripe, the DJM-850 is a fantastic four-channel mixer and perfect for any DJ who wants Professional-Club-Standard gear right at home (or on the road) at their fingertips.
