The Numark MT PRO 3 is a multi-functional DJ controller compatible with Serato, allowing for precise sound quality adjustments. I used it quite a bit until November. I recently got a new controller, so although this one is still usable, I'm selling it to declutter. The volume knobs, FX, Cue buttons, and other playback controls showed no issues when I played on the floor in November. Concerns: ● When pushing the volume fader that moves left and right all the way to the right (channel 2), sometimes the sound from channel 1 can be faintly heard (in actual play, the crossfader is usually engaged before this happens, so it didn't personally affect my play). ● Missing plastic parts on the individual volume faders and pitch faders (playing is not affected if you touch the metal parts directly; if anything, it allows for more precise movement). Due to the above concerns, I am selling this as junk and ask for no claims and no returns. If you absolutely want a discount, please comment in the comment section. - Brand: Numark - Model: MT PRO 3 - Functions: Treble, Mid, Bass, Master Volume, Cue Gain, Filter Adjustment - Controls: Sync, Cue, Shift buttons - Sliders: 2 channel faders - Compatible Software: Serato Thank you for viewing.
