HA 1

In-Ear Monitoring Headphone Amplifier

The HA 1 In-Ear Monitoring Headphone Amplifier is the ideal partner for singers, keyboardists, drummers, guitarists, bassists and other musicians. It establishes the connection between the monitoring signal from the mixing console, instrument or amp and your own headphones. Operation is child's play: Simply activate the unit with the volume control and adjust the desired volume for the headphone signal. With the stereo/mono source switch, easily accessible on the unit, the HA 1 can be adjusted to the respective input signal. The extremely compact and lightweight aluminium housing is equipped with a clip for fixing to a belt or waistband. The HA 1 has a status LED that changes colour depending on the available battery voltage. Two AAA batteries provide up to 12 hours of power, and changing the batteries is a very simple job thanks to the practical battery compartment with clip lock, which can be easily reached from the outside. The HA 1 is equipped with a combination jack for use with stereo jack (6.35 mm) and XLR cables for the input signal and a 3.5 mm stereo jack headphone output. On stage, in the rehearsal room or at home, the RockBoard HA 1 in-ear monitoring headphone amplifier always offers full control over the monitoring signal. In small clubs, in-ear monitoring improves the acoustics in the hall; when the band turns up the volume again, the signal is quickly adjusted and you can enjoy the same sound in every part of the room.
