Hear Back PRO

This is it – the simplest, most affordable digital solution to get everyone the mix they need to perform their best. This new system platform is completely modular and infinitely expandable, which means it has become the last personal monitoring system you’ll ever need.

With this system, there is no learning curve. Whether or not you’ve ever used a personal monitor mixer, the simple layout of this powerful system makes getting the right mix a quick and effortless experience. Based in Gigabit Ethernet, this framework paves the way for an impressive range of future possibilities.

The Hear Back PRO system consists of two main components: the Hub and the Mixer. The 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 Mixers (8 per Network Card), each over a single standard Cat5E/6 cable. And with the built-in HBus In/Out ports, multiple Hubs can be daisy-chained together, allowing for truly unlimited system expansion.

The Hear Back PRO system is available in a Four Pack as well as offering Mixers and Hubs separately.
