(courtesy of DJ warehouse facebook) thoughts guys??? EDIT WHAT IS THE RANE SL 4? The Rane SL 4 for Serato Scratch Live is the ultimate high-end solution for professional DJs. The SL 4 is the first standalone DJ interface to offer two USB ports, superior sound with 96kHz sample rate and 24-bit digital audio processing and galvanic isolation to eliminate computer noise and interference. Teamed with low latency ASIO and Core Audio drivers, the SL 4 can also be used as a high-grade studio production tool. All of this in one powerful package, masterfully crafted by Rane.

Two high-speed USB 2.0 ports for seamless DJ changeover and back-to-back performance. Aux Input for session recording or LiveFeed. Aux Output assignable to the SP-6 Sample Player and The Bridge. 48 kHz and 96 kHz sample rate switch on the SL 4 rear. 10-in 10-out USB sound card with any software supporting ASIO or Core Audio. Built in galvanic isolation for the purest audio signal. Four software-switchable analog Thru connections for regular vinyl or CD. Bus power from either USB port or the included external power supply.
