Blackstar Polar 4 Audio Interface – 4 Channel w/ St James Plug-In
Product Information
Introducing Blackstar’s POLAR audio interfaces, designed specifically for anyone who records guitar.
Our market research shows that most people who use an audio interface to record music at home record guitar. We conducted extensive Human Centred Design (HCD) which identified three main challenges people experience when recording guitar directly through an interface: poor feel / response, difficulty setting input levels without clipping and hard to use. Our POLAR interfaces overcome all these challenges making them the ultimate solution for anyone who records guitar.
