All four are on the front panel and include 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. 8 independent Outputs Two TRS monitor outputs are provided, plus stereo S/PDIF coax and two independent stereo headphone outputs – each with their own volume control, so artist and engineer can adjust their own monitoring settings. No breakout cables are required: all analogue inputs and outputs have their own connectors, 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. Tough, 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.
