The first standalone DJ interface to offer 2 USB ports, superior sound with 96kHz sample rate, 24-bit digital audio processing and galvanic isolation to eliminate computer noise and interference. Teamed with low latency ASIO and Core Audio drivers, the SL4 can also be used as a high-grade studio production tool. Also includes inputs for four turntables or CD decks, switchable in any combination, as well as auxiliary inputs and outputs. The Rane SL4 is a Serato DJ & DVS Enabled device and supports the use of Serato NoiseMap™ Control Vinyl or CDs with no additional license purchase.
