The Hear Technologies PROHBHFR is the hub mainframe for the Hear Back PRO system. This modular hub consists of four card slots, which can be populated with any configuration of input and/or output cards to fit your exact needs. Each Hub has the ability to supply signal and power to as many as 32 Hear Back PRO Mixers (8 per network card), each over a single standard CAT5e/6 cable. With the built-in HBus In/Out ports, multiple hubs can be daisy-chained together, allowing for truly unlimited system expansion.
