【Overview】 This is a set of two Pioneer CDJ-200s, a popular model. I believe it's the successor to the CDJ-100S, with significantly improved internal integration thanks to the addition of MP3 playback, beat loop, and loop cutter functions. Preventive parts have been replaced, and the units have been cleaned. Recommended for those who want a working and clean unit even when buying used. Their space-saving design makes them ideal for bars and cafes that occasionally host events. 【Why We Recommend This】 Although these are Pioneer's entry-level CDJs, they are well-built and reliable for use in a live setting. If you get used to these CDJs, you should be able to DJ without any problems on the latest CDJ models. While the jog wheels don't have touch sensitivity, this shouldn't be an issue for four-on-the-floor DJs. The LCD display that shows the BPM is surprisingly convenient. The accuracy is good, and it significantly reduces the time it takes to match the BPM. The loop cutter function is also useful for hyping up the crowd. It can be used regardless of genre if you're playing four-on-the-floor music, but I think it's especially frequently used in trance mixes. After maintenance, I mixed for about an hour using CD-Rs. I was able to use them comfortably without any problems. CD-R/RW discs can also be played (however, they may not play correctly depending on the disc characteristics, scratches, etc.). MP3 files can also be played. 【Maintenance】 *For both units. Mostly done for preventive purposes. ・Replaced 9 frequently used buttons on the panel with new ones (Play, CUE, loop-related, etc.) ・Removed and cleaned the keytops of all switches ・Cleaned the interior and exterior 【Appearance】 There are scratches on the left and right sides of the main unit, but otherwise, I think they are in good condition. Please see the images for details. 【Operation】 Maintenance and operation have been confirmed. Ready to use immediately. 【Accessories】 ・Power cords x2 If you purchase these along with the mixer I have listed, I will include RCA cables for connection as a bonus. I will also provide support if you have any questions about the connection. I am a non-smoker. These units have been maintained and their operation has been confirmed as described above. To prevent swapping and due to the age of the equipment, we ask for no claims and no returns except in cases such as the unit not powering on or if a unit clearly different from the one pictured is received.
