The silver version of Pioneer's DJM-850 Four Channel Professional DJ Mixer has a feature set that is sure to measure up in any nightclub. The DJM-850 features 8 analogue inputs, 4 outputs, and a high quality 24-bit/96kHz USB soundcard that supports up to 4 stereo channels on input and output. The mixer also offers compatibility with the Scratch Control Digital Vinyl System in Native Instrument's TRAKTOR SCRATCH PRO 2 and DUO 2 software.

The 4 analogue output channels can sourced from a wide set of connections, including six line inputs, four digital inputs, two turntable inputs, and a USB-connected computer. Each channel features a three-band isolator AEQ for real-time frequency manipulation. The 32-bit master D/A convertor carries out all the mixing functions, resulting in pristine audio quality with flexible capability. The mixer also incorporates a dual-shield structure for eliminating digital noise, and a high performance power supply for noise-free power.

The 13 onboard beat effects can be applied to any of the channels, or to the master outputs. An external processor can also be routed into the effects signal path via Send/Return jacks on the DJM-850's rear panel. Note: Serato Scratch Live DVS not supported
