Blackstar Polar 4 Channel USB-C Audio Interface

The Blackstar Polar 4 USB-C audio interface gives you the feel and response of a real guitar amp. It’s the only interface with an FET input stage and Enhance feature that mimics a valve amp’s input stage, restoring the touch, feel and tone of real amps when using amp plugins. You’ll get foolproof input level settings thanks to an input stage with 24V of headroom that never digitally clips. The Enhance switch makes all your amp plugins sound better by adding the characteristics of a real guitar amp.

Experience Your Amp Plugins Like Never Before

When you plug your guitar into a normal interface, the signal sounds weak and peaky, making amp plugins sound artificial. The Polar’s Enhance feature fixes this by replicating the behavior of a real valve amp’s input stage. Now your amp plugins respond like the real thing, with the touch, feel and tone of an actual amp. The Enhance switch works perfectly with pedalboards too, eliminating the need for a DI box.

Set Levels Quickly Without Clipping

The Polar’s innovative input stage provides an ample 24V of headroom, allowing you to drive it like an amp without clipping. Setting input levels and dialing in your tone has never been easier. The input stage’s impressive headroom gives you flexibility to explore different sounds without worrying about unwanted distortion.

High-Quality Preamps for Any Source

Polar’s preamps provide Neve 1081-inspired mic preamp and an Enhance function for mics that adds air and clarity to vocals. The mic and instrument preamps, alongside a 115dB noise floor, 48V phantom power and headphone outs for any impedance, make the Polar ideal for any musician recording guitar, vocals and more.

Simple Yet Powerful

While the Enhance feature improves feel, the Polar interface is also designed to be simple to use. You can quickly set levels without clipping and focus on what really matters—the music. The Polar’s innovative features, alongside an incredibly low noise floor, 48V phantom power and headphone outs for any impedance, make it the go-to interface for guitarists and vocalists.
