Description
The RockBoard® HA 4 is a highly compact headphone amplifier capable of distributing a stereo input signal to four separate sets of headphones.
Each output channel has its own amplifier and volume control, delivering professional audio quality for each headphone.
Its rugged and compact construction makes it an ideal choice for studios and live applications. Up to four people can listen to the main mix during a recording session, or four musicians can follow a backing track at their preferred volume during rehearsals.
Warning: This headphone amplifier can generate high sound pressure levels. Prolonged unprotected exposure can cause permanent hearing damage. If you experience hearing loss or ringing in your ears, consult a doctor.
