For stereo in-ear monitoring
RockBoard is best known for its smart solutions for pedalboards, but the German company's range goes well beyond the needs of pedal fans. The RockBoard HA 3 In‑Ear Amplifier is an active, wired headphone amplifier for a stereo in‑ear mix in a bodypack-style format. It features two mono inputs, which the amplifier can combine into a stereo signal: This stereo signal's left/right balance and overall volume can both be adjusted directly on the device. It's also possible to play two different input signals in mono, making it a handy tool for many typical studio or on-stage scenarios – for example, a drummer can hear both their personal click track and the band's mix. The unit can be powered either by a 9V battery or a 9V DC power supply with at least 100mA, neither of which is included.

Effective, secure, flexible
The RockBoard HA 3 In‑Ear Amplifier can be operated in either mono or stereo, with a switch directly on the control panel. In stereo mode, the balance control allows users to precisely adjust the stereo signal; there's also a volume control that sets the overall signal level. Thanks to the HA 3's active amplification, there's no need to integrate a separate headphone preamp into the setup, keeping even dual-input setups simple: To prevent the cables from being pulled out accidentally, both XLR combo sockets are equipped with a locking mechanism. The headphone amp works with any pair of headphones or in‑ear monitors that use a standard 3.5 mm mini‑jack.

Bring the whole band!
Designed for guitarists, bassists, vocalists, drummers, and indeed any other musicians, the compact RockBoard HA 3 headphone amp has an aluminium housing, making it lightweight and extremely robust, and a clear layout that means it can easily be integrated into any wired monitoring setup. Its practical metal belt clip gives artists the freedom to move around on stage as the music takes them: Equally, for fixed setups, the HA 3 can also be mounted on any microphone stand with its 5/8" thread and 3/8" thread adapter. Anyone looking for a cost‑effective in-ear monitoring solution that's both easy to use and reliably does the job will be more than happy with this handy little helper from RockBoard.

RockBoard's range focuses on pedalboards, which are available in numerous different designs to suit any application and budget.

The perfect balance for your personal mix
The RockBoard HA 3 In‑Ear Amplifier enables live performers and recording artists to quickly and independently adjust the volume and stereo image of their in‑ear mix in all kinds of musical situations: Whether it's in the studio, on stage, or in the rehearsal room, the HA 3 is a practical tool for musicians who want to be able to fine‑tune their sound on the fly. The option to bring in two signals separately offers even more flexibility – for example, an instrument can be sent to one channel and the band mix to the other, making it easy for musicians to dial in the perfect balance for their own personal monitoring mix.
