The Rane TTM 57SL was a groundbreaking product in the DJ world, combining a high-quality, professional 2-channel analog mixer with a built-in USB interface and deep integration with Serato software. This allows DJs to connect turntables or CDJs, run timecode vinyl/CDs to control digital music files on a computer, and apply software effects and functions (like cue points, loops, and the SP-6 sampler) using the mixer’s dedicated buttons, joysticks, and faders. The TTM 57SL is renowned for its robust construction, Rane's high-quality faders (which are often user-replaceable or upgradable to non-contact faders), and studio-grade audio fidelity. Its durable steel chassis is built to withstand the rigors of touring and live performance environments.
