Stereo Headphone Monitoring for Modern Pedalboards
The KMA Stereo Headphone Amp is a compact, high-quality solution for adding true stereo headphone monitoring to any rig. Whether you’re practicing silently, building ambient stereo setups, or dialing in tones late at night, it lets you hear your full signal chain exactly as it was meant to be heard.
Built around a premium analog, high-headroom design, it delivers a powerful and detailed headphone output that captures the true character of your pedalboard. From simple mono setups to fully immersive stereo rigs, the Stereo Headphone Amp adapts automatically to your configuration, keeping everything clear, balanced, and musical.
Practice, Create, and Explore Anywhere
With dual headphone outputs and a large master level control, the Stereo Headphone Amp makes it easy to monitor your sound at the perfect volume. The intuitive layout keeps things simple while still offering the flexibility needed for a wide range of setups.
An integrated AUX input with Bluetooth or 3.5 mm connection lets you bring in backing tracks, samples, or reference audio directly into your signal. The Mix control allows you to blend your instrument and AUX signal seamlessly, making it ideal for practice or songwriting.
Built for Real-World Rigs
The Stereo Headphone Amp features full stereo inputs and outputs, allowing it to sit naturally at the end of your pedalboard or after an amp sim. Flexible routing options let you run a full mix or a clean buffered thru signal to your outputs, depending on your needs.
Automatic detection of mono or stereo connections ensures a hassle-free setup, while still maintaining a full stereo AUX signal in your headphones when needed.
For live players, it also doubles as a personal monitoring solution, giving you direct control over your level when using IEM systems or dealing with inconsistent stage monitoring.
More Than Just a Utility
The input stage features a dedicated Input Level control with clip indication, allowing you to match different signal sources or even push the preamp into subtle, musical saturation for added character.
Compact, flexible, and designed with real-world use in mind, the KMA Stereo Headphone Amp brings studio-quality monitoring to your pedalboard without unnecessary complexity.
