RockBoard HA 3 Two-Channel In-Ear Monitoring Headphone Amplifier
The RockBoard HA 3 In-Ear Monitoring Headphone Amplifier is a professional two-channel personal monitoring solution designed for musicians who require precise, high-quality in-ear monitoring on stage, in rehearsal rooms, or in the recording studio. Built for vocalists, guitarists, bassists, keyboardists, drummers, and other performers, the HA 3 delivers powerful, high-fidelity monitoring with flexible connectivity and intuitive controls.
The amplifier supports two independent monitor feeds or a stereo monitor mix, allowing musicians to create the perfect monitoring environment. Dedicated Volume and Balance controls provide precise adjustment of overall listening level and stereo panorama, while the Mono/Stereo switch offers compatibility with both mono and stereo monitoring systems.
Constructed from durable lightweight aluminium, the HA 3 can be worn using its sturdy metal belt clip or securely mounted to a microphone stand using the included 3/8″ and 5/8″ adapters, making it equally suitable for stationary performers and vocalists.
Two professional locking XLR/TRS combo inputs ensure reliable connections by preventing accidental cable disconnection during performances. The amplifier features a standard 3.5 mm stereo headphone output for connecting in-ear monitors or headphones.
The HA 3 offers flexible power options, operating from either a standard 9V battery or a 9V DC center-negative pedal power supply (not included). An easy-access battery compartment, power LED, and ON/OFF switch make operation simple while maximizing battery life.
Whether you’re performing on stage, rehearsing with your band, or recording in the studio, the RockBoard HA 3 delivers dependable, professional-quality personal monitoring with complete control over your monitor mix.
