POLAR, Making Recording Easy POLAR solves the frustration guitarists often experience when recording guitar with a FET input stage. When Enhance is enabled, a unique set of electronic components is introduced into the signal path to recreate the input stage of a classic tube guitar amplifier. This circuit mimics the behavior and characteristics of a tube amplifier, enhancing the tone, touch, feel and response. When POLAR "Enhance" is enabled, Blackstar's innovative input stage will never digitally clip. No more ruining recording takes or the hassle and confusion of setting the "right" levels. POLAR allows musicians to control the interface just like they would a real amplifier's preamp. The POLAR interface was developed within a human-centered design framework to create a user-friendly solution that allows musicians to focus on what matters most: the music. It's easy to see why Blackstar's POLAR is the perfect audio interface for anyone who wants to play and record guitar.

Features

• 4 channel audio interfaces designed for guitarists.
• 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.
• High power headphone outputs and monitor output, with independent monitor and headphone control.
• Mic preamp based off of the most renowned vintage studio preamps.
• Comes with POLAR Control mixing software, giving the control to adjust and fine-tune the levels, panning and routing of your monitoring.
• Runs on USB 2.0 bus power, with +48V switch for microphones that require phantom power.
• POLAR 4 also adds MIDI capability and dual headphone outputs.
