## Description

Introducing Blackstar’s POLAR audio interface, 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.

## Features

- The only audio interface in the market with a FET input stage and “Enhance” feature that mimics the behaviour, characteristics, and electronics normally found on the input stage of a valve guitar amplifier. Plugging a guitar directly into a normal audio interface produces an anaemic signal with peaky transients, which makes playing through amp plugins sound like… a plugin, not an amp.
- Our innovative input stage will never digitally clip, allowing the user to drive the interface like an amp. The input stage has an impressive amount of headroom running on +/- 12V giving 24V headroom, an outstanding comparison to competitor units at 5V. Setting guitar input levels and improving your tone has never been easier
- We put an equal amount of effort into designing the POLAR MIC preamps, which boast a response that matches one of the most famed vintage British Preamps in studio history
- Although designed with the recording guitarist in mind the Blackstar Polar 4 audio interface will be perfect for Podcasting / Gaming / Streaming and other Pro Audio Recording. POLAR 4 also adds MIDI capability and dual headphone outputs
- Including Free Full St James Guitar Software Suite - ableton Live Lite - Relab LX489 Essentials - Polar Control Software
