A "Bodypack" Format That Has Become a Standard for Personal Mixes

On stage, monitoring is a key element: a good headphone mix helps you play more accurately, stay rhythmically in place, and reduce fatigue. Bodypack-format headphone amplifiers have established themselves as a simple solution to transform a console output or a monitoring line into individual monitoring. This model fits within that logic: compact, battery-powered, and designed for the field, it meets the essential needs of an in-ear system without unnecessary complexity.

Who Is It For and What Are the Uses?

This active headphone amplifier is aimed at musicians and technicians who want immediate personal monitoring: singers using in-ear monitors, guitarists and bassists who want to keep a clear reference, drummers who need precision, as well as keyboardists and musicians in full bands. It is also well suited for situations where the same source needs to be shared: the mono mode ensures secure listening even if the console provides a non-stereo signal, while maintaining a comfortable level thanks to its maximum gain of 14 dB.

Key Features and Stage-Oriented Design

Stereo or Mono: Instant Adaptation

The stereo/mono switch is a real asset in live environments. In stereo, you enjoy a wider image (useful for locating vocals, instruments, and effects). In mono, you ensure coherent listening when the source is not stereo or when the setup requires a combined signal.

Combo Input and Dedicated Headphone Output

The combo XLR / 6.35mm Jack input allows easy integration with a console, monitoring system, or line output. The 3.5mm Jack headphone output is ideal for most in-ear monitors and portable headphones, while maintaining a 10 Ohm output impedance for stable powering of many transducers.

Autonomy and Practicality

Powered by 2 x 1.5 V batteries, the device is fully autonomous. The battery indicator helps anticipate replacement before a concert or rehearsal. With its belt clip, it remains accessible and discreet: you keep your monitoring close without positioning constraints.
