About Blackstar POLAR 2

An exceptional tool for guitarists, the Blackstar POLAR 2 2-Channel USB-C Guitar Audio Interface is engineered to deliver superior recording guitar tones with precision and clarity. This premium 2-channel USB audio interface is crafted by guitarists for guitarists, ensuring an intuitive, high-quality recording experience. It features two high headroom FET input channels that accommodate instruments, line inputs, and microphones, offering ultra-low noise and exceptional headroom. This design captures the richness and depth of your music effortlessly, providing an optimal sonic foundation for your guitar tones.

The POLAR 2 is equipped with a high-output headphone amplifier and +48V phantom power, making it ideal for use with condenser microphones and professional monitoring. Its visual level meters and proprietary "Enhance" switch add to its versatility, making it a must-have tool for any guitarist. The standout "Enhance" switch, when activated on the instrument input, introduces a unique circuit that replicates the input stage of a real valve amplifier, complete with its non-linear behaviors and characteristics. This feature allows you to drive the POLAR's preamps like a genuine valve amp, ensuring smooth handling of dynamic guitar signals and eliminating harsh tones.

Additionally, the POLAR 2 is equipped with a world-class microphone preamp, inspired by legendary vintage studio preamps, delivering warm, rich tones and authentic character to your recordings. It comes bundled with a comprehensive studio software collection, including the full St. James Plugin Suite, Ableton Live Lite, ReLab LX480 Essentials Reverb, Melodyne Essential, and more, providing everything you need to start recording immediately.

The Blackstar POLAR 2 also includes the versatile Polar Control mixing software, offering zero-latency monitoring and "loopback" functionality. This feature streamlines your signal routing workflow, eliminating the need for bulky hardware mixers and simplifying the recording and mixing process. With high-output headphone amps and balanced monitor outputs, each with individual level control, the POLAR 2 ensures easy level mixing during both playing and recording sessions.

Powering the device is straightforward; it can run directly from your computer using USB 2.0 bus power with the included USB-A to USB-C cable, or you can use the DC 5V Input for microphones requiring phantom power. In summary, the Blackstar POLAR 2 2-Channel USB-C Guitar Audio Interface is a versatile, high-quality audio interface that equips guitarists with everything needed for professional-grade recording and monitoring.
