RockBoard HA-4

The RockBoard HA 4 is a compact headphone amplifier that allows you to distribute a stereo input signal to four headphone jacks. Each channel is equipped with its own amplifier and independent volume control. This allows each user to adjust the volume to their liking without affecting the other outputs. Ideal for situations where accurate monitoring is essential, such as in the studio or on stage.

For studio, rehearsal and more
Thanks to its rugged and compact design, the HA 4 is excellent for use in a variety of environments. Whether you're working on a recording, rehearsal or live setup, this headphone amplifier allows up to four people to simultaneously listen to the same source, each at their own level.
