Featuring four award winning preamps the Focusrite Scarlett 18i8 is the perfect audio interface for large home or project studios and is highly capable of many tasks including recording a whole band live.

Eighteen inputs, eight outputs and four high quality mic preamps

The frist interface from Focusrite to have four of their award winning mic pres, the Scarlett 18i8 features two inputs with mic/line/instrument capability and two more that can handle mic/line. Four line inputs on the back of the unit can be used for furhter connection of other instruments or sources, perfect for studio work. ADAT is a further connection you could use, allowing you to connect a mic preamp such as the OctoPre MkII for further connectivity and to take advantage of all 18 inputs.

Robust and feature packed

All four of the inputs of the Focusrite Scarlett 18i8 have the trademark "halo" level indicators that light up green or red to show your signal level and whether it is overloading the preamp. Two independent headphone outputs with their own mixes mean you can send different mixes to different players or engineers.
