Manufactured in 2015 Power-on playback, LINK function, loop, SYNC, etc. have all been checked. Non-smoking, no pets, never taken to clubs or outdoors. The platter, fader, and CUE/PLAY buttons show no signs of wear. I purchased them new and have been using them. One unit underwent manufacturer maintenance in 2018. There are minor scratches, but they are in good condition. The power cable (IEC connector) is the original one from when I purchased it. (RCA cables and LAN cables are not included) The hard case in the image is not included. No price reduction. Transactions may be canceled for accounts that have not completed identity verification. I sold them once, but there was a problem with the disc ejection mechanism. After a return, I confirmed that they start correctly after maintenance. The following is a description of the manufacturer's features: ・As a feature unique to the CDJ900Nexus, you can divide one beat of audio into the length of a specified beat and play it back. "BEAT DIVIDE" allows you to instantly create a variety of beat arrangements without disrupting the rhythm of the song with simple button operations. ・MIDI control of DJ software is possible. ・"MY SETTINGS" allows you to instantly reflect your customized settings. Functions: ・"TRAFFIC LIGHT" displays songs that harmonize with the key of the song being played on a multi-player connected via "PRO DJ LINK" in green. ・"ACTIVE LOOP" automatically starts a loop when a specified point is played. ・"4 BEAT LOOP" allows you to create an accurate 4-beat loop with the push of a button. ・Equipped with an "auto-standby" function that switches the power to standby mode after a certain period of inactivity, which is environmentally friendly.
