Whether you’re a guitarist, bassist, vocalist, drummer, or keyboardist, this compact yet powerful headphone amplifier ensures that you hear every detail of your mix with precision, allowing you to stay in perfect sync with the music.

Total Control Over Your In-Ear Mix

Nothing is more frustrating than struggling to hear yourself in a live setting, whether you're competing with blaring stage monitors or getting an inconsistent mix from the sound engineer. With the RockBoard HA 1, you take control of your own in-ear monitoring experience. No more guessing, no more struggling—just pure, direct sound delivered straight to your ears.

Versatile Connectivity for Any Setup

One of the standout features of the HA 1 is its combo input jack, which accepts both 6.35 mm (1/4") TRS and XLR cables. This means seamless integration with a wide variety of audio sources, from mixing consoles to instrument amplifiers and personal monitor systems. Whether you’re connecting it to a dedicated monitor feed or plugging directly into a headphone output, this unit adapts to your specific setup with ease.

The stereo/mono source switch ensures compatibility with different types of signals. Whether you’re getting a stereo mix with full panning and depth or a mono feed for simple monitoring, you can adjust instantly to match your needs.

Built for the Stage, Designed for Convenience

When performing live, mobility is key, and the HA 1 is built to move with you. The sturdy aluminum housing is lightweight yet rugged, designed to withstand the rigors of touring, rehearsals, and daily use. The compact size (141 mm x 30 mm x 36 mm) and solid belt clip make it easy to attach to your waistband, guitar strap, or belt, keeping your monitoring system securely in place while you perform.

The volume knob also acts as the power switch, making operation incredibly simple—turn it up, and you're ready to go! No need to fiddle with complex settings; just dial in your preferred listening level and focus on your performance.

Pristine Sound Quality with Plenty of Power

Of course, none of these features would matter if the HA 1 didn’t deliver exceptional sound clarity and power—and it absolutely does. With a maximum output of 2 x 110 mW at 16 Ohms and an incredibly low output impedance of less than 0.1 Ohm, this amplifier ensures that your in-ear monitors or headphones receive a strong, noise-free signal without distortion. Every nuance of your performance is captured, from the deepest bass notes to the most delicate high frequencies, ensuring a clear and accurate mix that lets you play with confidence.
