A basic Hear Back system consists of a Hub and personal Mixers connected using standard CAT5E cables. A single Hub supplies signal and power to a maximum of eight Mixers. That’s one for you and everybody in the band. If that’s not enough, the Hubs can be daisy-chained using the HearBus In and Out for virtually unlimited system size. The Hear Back Hub can accept analog input signals from audio mixers, auxiliary, matrix, monitor, and/or direct outputs.

The ADAT input can come from digital audio workstations, digital recorders, or digital mixers. For front of house or remotely located digital mixers, we also have the Extreme Extender ADAT In/Out that converts ADAT optical, which has very limited distance, to the HearBus for transmission of up to 500 feet.
