The RockBoard® HA 3 In-Ear Monitor Amplifier is the core of a high-quality personal two-channel monitoring system for musicians. This lightweight unit is designed for performers who remain in a relatively fixed position on stage. It provides professional sound quality and a high-volume, high-fidelity signal allowing users to clearly hear a stereo or two separate monitor signals on any stage or in any studio. It can be used with a belt clip or mounted on a microphone stand using the integrated screw-on adapter. The HA 3 can be battery operated and features a status LED that changes color to indicate the remaining battery life. Changing batteries is very simple and quick thanks to the easy-access battery compartment. When mounted on a microphone stand, the HA3 can alternatively be powered by connecting a regular pedal power supply unit (not included) supplying center-negative 9 VDC. The HA 3 is equipped with two combination input jacks for use with 6.35 mm stereo TRS jacks or XLR connectors. Headphones or IEM are connected to a 3.5 mm stereo jack headphone output. Simply activate the unit with the ON/OFF switch and adjust the desired volume for the headphone signal. Use the stereo/mono source switch depending on your connected audio source(s) and use the balance control to adjust the stereo panorama for your headphones.
