Vestax 4-channel DJ mixer with effects and monitor function. - Model: PMC-280 - Brand: Vestax - Number of channels: 4 - Monitor function: cue selector - Effects: effector The last time I used it was 5 years ago, and it's been stored in a closet since then, so this is based on my memory. I believe two of the four channels had weak output, and the crossfader only produced sound on one side. The effects worked fine, and I enjoyed DJing with it at home. I'm reluctantly selling it due to space issues at home. I can't find the power cable. Please understand that this is a used item.
