Summary: Pure "consumer grade." This machine failed after a few weeks of on-air usage at our radio station. Upon opening the box to troubleshoot we found loose connections between circuit boards, circuit boards held in place by their connectors, and a 1970's style circuit board with wire jumpers instead of vias. The CD mechanics are plastic. Professional? Definitely not.
Summary: I purchased this exact model over ten years ago along with a double CD player of the same line. I've used these as a mobile DJ all this time and never had a problem. And as much as I move these players around and getting banged up, they still work perfect.
Summary: I install pro-level sound systems in gyms, stadiums, churches and athletic fields. I've installed several of the Numark MP-102 CD players for my customers because of it's ease of operation, price vs quality, features and ability to play just about any format of recordings. If you're setting up a home studio or preparing to rock the house of 10,000 listeners, you can't go wrong with this unit. The +/- 16% pitch control and stutter loop features are always a hit.
