Don’t be limited by your interface’s connectivity. 18 separate inputs let you connect just about anything you want, and leave your instruments permanently set up and ready to record. The four combination inputs on the front each have a natural-sounding Scarlett mic preamp, 48V phantom power and superior linear gain. Backed by 30 years of design experience, they guarantee low noise, minimal distortion and a dynamic range that is unrivalled in this class. On the back are four more line inputs for connecting your synths, keyboards or mixers, and two additional S/PDIF inputs for recording digital sources. For even more inputs, connect an eight-channel mic pre like the Focusrite OctoPre Mk II, for a total of 16 analogue inputs with 12 preamps Focusrite has been perfecting audio conversion for over 20 years. Their class-leading digital conversion operates at up to 24-bit and up to 192kHz, so you capture every nuance of every performance in crystal clear audio without any unwanted noise or hum, even when you’re playing softly. Focusrite has redesigned Scarlett 18i8's instrument inputs and given them plenty of extra headroom, so you can handle extreme levels without any unwanted clipping or distortion. If you’re recording extra loud instruments, you can also engage the 10dB pad in Focusrite Control software.
