Pioneer's RMX-500 with effect control function. - Model Name: RMX-500 - Brand: Pioneer - Input/Output Terminals: USB, RCA Output, Headphone Output - Features: Effect Control, Release FX - Design: Black color, Round knobs - Power: DC 5V Thank you for viewing. I'm selling it because I'm upgrading my equipment, even though I've used it for many years. There are some minor scratches, but I think it's still a usable piece of equipment. There is no outer box. Included accessories: Power cord only. Thank you for your consideration.
