Hear Technologies Hear Back Pro Four Pack

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 most intuitive digital monitor mix solution for recording studios, rehearsal spaces, and live sound applications. This Four Pack contains everything you need to make 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. With the Hear Back system each user can easily dial in their personal monitor mix and interact with the engineer and/or other performers.

The Hear Technologies Hear Back Pro System consists of two main components: the Hear Back Pro Hub Mainframe and the Hear Back Pro Mixer. The Hub Mainframe 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 CAT5 cable. And, with the built-in HBus In/Out ports, multiple Hubs can be daisy-chained together, allowing for truly unlimited system expansion.

With the latest Firmware update (as of Aug 2024), and Pro Connect software, the Hearback Pro systems allows 32 channel digital input cards (with Dante, Waves, MADI cards), submixing up to 16 stereo channels on each of the 16 knobs per Mixer. PRO Connect provides a web-based interface to update, configure, and control your PRO Mixers and PRO Hubs.

Optional Digital Overlays
The Hear Technologies Pro Digital Overlays are ultra-thin LED faceplates for electronic labeling of your Hear Back Pro Mixers. These attachable upgrades modify and expand the display of channels and mixer functions through high contrast LED graphical displays. These overlays will be installed on your mixers so you are ready to go right out of the box. Furthermore, you save $294 by adding the digital overlays now and bundling with your Hear Back Pro Four Pack.

Optional Hear Technologies Hear Back Pro Accessory Bundle
The Hear Technologies Hear Back Pro Accessory Bundle includes everything you need to quickly set up and use your Hear Technologies Hear Back Pro Mixer in the studio or while on the road. This bundle includes a stand, a tilt adapter, a headphone hanger and a talkback microphone. Front End Audio is including these accessories which we know you will need. With this bundle you are ready to start using your mixer to its fullest potential.
