Hear Back PRO system

Made up of 2 main components: the Hub and the Mixer. The modular Hub unit consists of 4 card slots which can be populated with any configuration of input and/or output cards to suit your exact needs. Each Hub has the ability to supply signal and power to as many as 32 Mixers (8 per Network Card), each over a single standard CAT5e/6 cable. With the onboard HBus In/Out ports, multiple hubs can be daisy-chained together, allowing for truly unlimited system expansion.

The Hear Back PRO Mixer provides local control of up to 18 channels of audio (16 mono channels + AUX IN + Intercom IN), and can receive power and audio over a single Ethernet cable, up to 500ft from Hub to each Mixer.
