I'm selling my DJM-500, along with CDJ-30 and CDJ-50, as next-vintage equipment, as I haven't had the chance to use them much lately. I think it's a classic from the 90s. It has been tested and cleaned, so I think it will last a long time. 4-channel DJ mixer, equipped with effects, master level adjustment possible. - Model: DJM-500 - Number of channels: 4 channels - Effect function: Equipped - Master level: -14dB to +6dB - Crossfader: Equipped - Monitor level: Equipped Thank you for looking.
