The Hear Technologies Hear Back Pro Four Pack offers independent multi-channel mixing for up to four performers in the studio or on stage. This system platform is completely modular and infinitely expandable, which means it has become the last personal monitoring system you'll ever need.
The Hear Technologies Hear Back Pro Four Pack is the simplest, most affordable digital solution to get everyone the mix they need to perform their best. Containing one Hear Back PRO Hub, four Hear Back PRO Mixers, four 50’ Cat-6 cables, and two DB25 to 1/4 TRS analog breakout cables, it makes quality personal monitoring effortless. The Hear Back Pro Four Pack offers 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 Technologies Hear Back PRO System consists of two main components: the Hear Back PRO Hub and the Hear Back PRO 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.
Now with V6 Firmware
Assign each knob of a PRO Mixer to any mono channel, stereo pair of channels, or even a submix of up to 16 channels with the V6 update. Configure each Mixer differently and add up to 128 input channels to the system using additional Input Cards and Hubs (32 channels of inputs per Hub).
