Unlock the full potential of your Kemper Profiler with British Audio’s exclusive 300W x 300W Stereo Modification. While the Kemper Profiler revolutionized digital amp modeling, its stock power amp is mono-only, leaving your stereo effects—reverbs, delays, chorus, and more—collapsed into a single speaker when using the powered output.

At British Audio, we decided to change that.

Why Go Stereo?

Since its release, the Kemper Profiler has dominated the stage, studio, and home setups, offering players studio-quality amp tones at any volume. With its responsive tube-like feel, massive selection of amps, and built-in effects, the Kemper remains the go-to choice for thousands of musicians worldwide. However, the powered version still limits players to mono, even though Kemper’s XLR and ¼" outputs retain stereo imaging.

We solved this problem by engineering a stereo upgrade that seamlessly integrates into your Kemper, allowing you to fully experience stereo sound through your favorite cabinets without any change in tone.
