18 separate inputs

At the heart of 18i8 is a set of four Focusrite mic preamps with up to 60dB gain, designed specifically for Focusrite’s computer audio interfaces. The first two offer Mic/Line/Instrument on universal XLR/TRS connectors while 3 and 4 offer Mic/Line capability on universal XLRs – all four on the front panel with pads and 48V phantom power. Four more line inputs are provided on TRS connectors. An ADAT optical digital connector provides eight additional digital inputs that can also be used with external mic preamps like Focusrite's OctoPre Mk II to increase the number of mic inputs the 18i8 can handle to 12. A stereo S/PDIF coaxial input is also included.

Scarlett 18i8 - 8 independent outputs

8 independent outputs

On the output side, there are two TRS monitor outputs, stereo S/PDIF coax, and two independent stereo headphone outputs, each with their own volume knob so artist and engineer can control their own personal monitoring. All analogue inputs and outputs have their own connectors, so no breakout cables are required, and all feature Focusrite precision 24-bit, 96kHz sampling A/D and D/A conversion to get the most accurate signal possible into and out of recording applications on Windows®, Mac® and now iOS® apps.

Scarlett 18i8 - Tough and innovative hardware

Tough and innovative hardware

Scarlett 18i8 is housed in a compact red unibody metal case to withstand the rigours of the road – and the studio. Input level controls feature signal halos – LED rings around the level control that give a simple and immediate go/no-go level indication: green means there is a recordable signal while red indicates overload. A large main monitor knob with mute button means that main monitor levels are always at your fingertips.
