A single Hear Technologies Hear Back OCTO Hub supplies signal and power to a maximum of eight Mixers. To expand your system, the Hubs can be daisy-chained using the HearBus In/Out for virtually unlimited system size. The Hub accepts analog input signals from an audio mixer such as auxiliaries, matrix outs, sub outs, monitor outs, and/or direct outputs. The ADAT input can come from digital audio workstations, digital recorders, or digital mixers.
