Flexible AUX And Bluetooth Connectivity
With built in Bluetooth audio streaming and a 3.5mm stereo AUX input, the Stereo Headphone Amp makes it easy to play along with backing tracks, trigger samples or stream music directly from your phone, tablet or computer.
The AUX signal can be blended seamlessly with your main instrument signal using the dedicated Mix control, giving you complete control over your monitoring balance.
Whether practising at home or integrating tracks into a live setup, the Stereo Headphone Amp offers exceptional flexibility.
Intelligent Stereo And Mono Routing
The Stereo Headphone Amp automatically detects connected signal paths and intelligently adapts for:
Full stereo operation
Mono operation
Mono in stereo out configurations
Unused channels are automatically summed to the centre, ensuring smooth operation in any setup. Even when using mono instrument signals, AUX playback remains fully stereo through the headphone outputs for an immersive listening experience.
Ideal For Modern Live Monitoring
For live musicians using wired or wireless in ear monitoring systems, the Stereo Headphone Amp provides direct control over personal monitoring levels without relying entirely on venue monitor mixes.
By feeding a monitor mix into the AUX input while routing your own signal directly through the headphone outputs, players can achieve tighter timing, lower latency and greater personal control over their monitoring environment.
The selectable FULL and THRU output modes allow the AUX signal to be excluded from the main outputs when needed, making the unit highly adaptable for professional stage use.
Powerful Controls And Musical Saturation
The large Phones control adjusts the master headphone level and is large enough to operate easily by hand or foot during performance.
An independent Input Level control allows users to optimise gain staging for instruments, amp simulators or full pedalboard signal chains. Push the input harder for subtle analogue saturation and console style warmth, while the built in Clip LED provides visual feedback when levels become too hot.
Compact Utility With Boutique Quality
Hand built in Berlin, Germany, the Stereo Headphone Amp combines premium analogue circuitry with compact practicality and modern connectivity. Designed for pedalboards and studio setups alike, it provides enormous flexibility in a surprisingly compact footprint.
And yes, the illuminated KMA Bear eye looks fantastic too.
