The Pyle PDJ480UM Rack Mount Professional Dual DJ Controller with scratch function is rack-mountable for an easy installation. It's a modern take on the classic turntable setup - no more vinyl, just MP3s. Each input takes a USB stick or SD card with MP3s - then mix and scratch up your music like a pro. Take total control of your sound with pitch control, looping and the 3-band EQ on both channels. The bright blue LCD display shows playback information and ID3 tags. Supports high capacity SD and USB sticks up to 16 GB for plenty of music. Equipped with dual RCA outputs and inputs (phono & line).
