RockBoard HA-3

The RockBoard HA 3 in-ear monitor amplifier is a wired, two-channel, high-quality monitoring system for musicians. This lightweight device is designed for artists in a relatively fixed position on stage. It provides professional sound quality and a signal with high volume and high fidelity, 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 adapter. The HA 3 is battery operated and has a status LED that changes color to indicate remaining battery life. Changing batteries is very easy and quick thanks to the easily accessible battery compartment.

If the HA3 is mounted on a microphone stand, it can also be powered by connecting a regular pedal power supply (not included) that provides (mid-negative) 9 VDC. The HA 3 is equipped with two combined input jacks for use with 6.35 mm stereo TRS jacks or XLR connectors. Headphones or IEMs are connected to a 3.5 mm stereo headphone output. Activate the unit with the ON/OFF switch and set 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 panel for your headphones.
