The Focusrite 18i8 and 18i20 all have ADAT connections that allow you increase your channel count by connecting another digital device. In this article we\u2019ll show you how to connect, sync, and route ADAT devices with your Scarlett series interface. This guide breaks down into two parts:<\/p>\n\n\n\n
ADAT<\/a> is short for Alesis Digital Audio Tape. ADAT inputs are typically used for adding more input channels via additional microphone preamps and audio interfaces. Both 18i8 and 18i20 have ADAT Optical input jacks for eight more inputs at 44.1 & 48 kHz, and only four additional channels are available when recording at 88.2 & 96 kHz. ADAT Outputs are generally used to send signal out of your Scarlett to external devices like headphone distribution systems and D\/A converters. Just like ADAT inputs, higher sample rates will also reduce the amount of output channels.<\/p>\n\n\n\n Return to top<\/a><\/p>\n\n\n\n\n\n Connecting another device to your Scarlett via ADAT is really just a matter of connecting the cables, synchronizing both devices, and then setting up the routing. Synchronizing two digital devices might sound a little intimidating but if you follow the steps below, you\u2019ll be surprised just how easy it is. <\/p>\n\n\n\nConnect to Scarlett with ADAT<\/h2>\n\n\n\n
