Want to use your favourite in-ears without a wireless system? Simply get the RockBoard HA 1 headphone amplifier and hook it up to the AUX or headphone output of your mixer.
With the RockBoard HA 2 In Ear Headphone Amplifier, you adjust how loud the signal for your in ears is that you get back wired from the front of house. Also works with any other line signal, of course.
In a band, as a player you may have the desire to get a complete stereo picture on your in-ears. For example, if you're a keyboard player who wants to hear your synths in full. The RockBoard HA 3 is something then!
