Blackstar Polar 2 Audio Interface – 2 Channel w/ St James Plug-In
Product Information
Blackstar’s mission with POLAR is to create the go-to audio interface for guitarists that seek the ultimate recording guitar tone.
POLAR 2 is a 2 channel USB audio interface built by guitarists for guitarists. It features 2 high headroom FET input channels for instrument, line and microphone, a high output headphone amp, +48V phantom power for condenser microphones, balanced outputs for professional monitoring, visual level meters and the proprietary “Enhance” switch.
POLAR comes bundled with the studio software collection including the full St. James Plugin Suite and everything you need to start recording now!
Features
- 2 channel audio interface designed for the recording guitarist.
- High-headroom FET input stage that improves tone and quality of signal and accommodates for wide range of instrument types, effect pedals and microphones.
- ‘Enhance’ feature that introduces electronics into the signal path that replicate the sound of a classic guitar amplifier.
- ‘Enhance’ completely prevents digital clipping for instrument inputs. Drive this interface like it’s a real amp and be free of the fuss of setting the ‘correct’ levels.
- ‘Enhance’ on the microphone or LINE inputs gives natural clarity and air to vocal and acoustic guitar performances.
- The ‘Enhance’ feature negates the need for extra hardware and expensive DI’s to capture high quality guitar signal. It’s all built into POLAR.
