Hear Technologies HEAR-BACK-HUB
Signal and Power Hub for Hear Back System

OUR PART #  HEAR-BACK-HUB


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.

Features:

  • Three switch selectable 8-channel input sources:
        * ADAT Optical
        * Analog
        * HearBus
  • 24-bit A/D converters
  • Digital inputs: 44.1KHz and 48 KHz sample rates
  • Less than 1.5 milliseconds system delay
  • 3-LED four-level metering
  • Standard CAT5E - delivers power and signals to mixers
  • Daisy-chain for very large systems
  • Internal universal input power supply
  • 1 RU chassis
