The DJM-900NXS Nexus 4-Channel DJ Mixer is built on Pioneer’s first 64-bit mixing processor. This means the mixer’s sound is full of nuance and precision, from fine-tuned EQ to the fader and FX controls. The DJM-900NXS’s FX section is formidable, with Sweep, Filter, Crush, Dub Echo, Noise and Space available on each channel. The mixer also comes with independent Send/Return ports, 4 phone inputs, and 2 USB ports, making it a really flexible modern mixer.
