Audio Interface Sitting on the desks of more musicians and producers than any other, the Scarlett range of audio interfaces means studio-quality sound for all your instruments – and 4i4 is the interface of more. Capture more of your ever-expanding setup with more inputs, more outputs and more connectivity. Four balanced line inputs, for connecting synths or other line-level audio, and four balanced outputs, for monitoring and effects sends. Two of the best performing Scarlett mic preamps the range has ever heard – now with Air – for miking up guitars or recording vocals. Two high headroom instrument inputs, for plugging your guitar or bass straight in. Loopback, for grabbing a stereo feed of any combination of hardware inputs and software playback, no cables needed, for simple sampling, streaming or podcasting.
