The Pioneer DJ DJM-S9 is a professional 2-channel battle mixer for Serato DJ and is well suited for DJing in clubs, concerts, music studios, and live events. The mixer is especially useful for DJs who play Serato because it includes two internal 24-bit/48 kHz Serato-certified USB soundcards. Each input channel includes stereo RCA for both CD/Line as well as RCA phono inputs for turntables with ground. For outputs, the unit features stereo balanced XLR and unbalanced RCA connections, as well as stereo 1/4″ TRS booth outputs.

 

The mixer’s front panel offers a variety of controls with each deck offering trim, 3-band EQ, and a single filter knob offering high-pass and low-pass effects. For dynamic live mixing there are 8 multi-colored pads for each deck giving access to Hot Cue, Roll, Slice, Loop, and more. Additional features include a microphone input with dedicated high and low EQ, talk-over function, level, and echo, as well as an auxiliary input for adding an additional stereo input via RCA.
