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.

System Features
Hear Back PRO Mixer Features
The Hear Back Mixer is equipped to mount to any standard mic or desk stand using the built-in 5/8" threaded socket located on the back of the mixer.
- Local control of up to 18 channels of audio (16 mono channels + AUX IN + Intercom IN)
- Receive power and audio over one Ethernet cable, up to 500’ from Hub to each Mixer
- 24-bit Delta-Sigma D/A and A/D converters
- Volume/panning/stereo link control of all 16 channels of audio
- Store up to 4 recallable presets
- Intercom allows communication to anyone with a Hear Back PRO Mixer
- 1/8” and 1/4” headphone jacks
- Balanced mono/stereo, line level outputs
- Selectable 1/8” TRS stereo unbalanced and XLR mono balanced (with 15V phantom power) AUX inputs:
- Microphone input for crowd / ambiance mic or intercom use
- Drum module / metronome or local mix input
Hear Back PRO Hub Features
A single Hub supplies signal and power to a maximum of eight Mixers. To expand your system, the Hubs can be daisy-chained using the HearBus In/Out for virtually unlimited system size. The Hub accepts analog input signals from an audio mixer such as auxiliaries, matrix outs, sub outs, monitor outs, and/or direct outputs. The ADAT input can come from digital audio workstations, digital recorders, or digital mixers.
- Three switch selectable input sources:
- ADAT® Optical
- Analog
- HearBus
- 24-bit A/D converters
- 44.1KHz and 48KHz sample rates
- Multi-color, four-level metering
- Daisy-chain for expanded systems
- Internal universal input power supply
- 1 RU chassis
App
Control Hear Back PRO Mixers, simply by connecting your PRO Hub to a wireless network!
- Connect the HBUS IN port (located on the back of your PRO Hub) to a gigabit-speed LAN port of your wireless access point. Launch the app, and watch your mixers populate in the list.
- Name the Mixers & channels, these will persist between sessions.
- Group Mixers together, allowing them to control each other, by either:
- Long-press mixers in the list to drag-and-drop into groups
- Swipe left on any mixer in the list to reveal additional options (including grouping control)
- Setup lockouts on knobs, buttons, features, and presets on a per-Mixer basis.
- Easily update Mixer firmware, wirelessly.
- Control the brightness of the Mixer's LEDs (useful in darker rooms).
New Features
- View sampling rate, clock status, input switch selection, and internal Hub temp
- Monitor all 16 input signal levels
- Mixer control lockouts for pan, aux, preset, intercom, any or all channels, and master knob
- Disable advanced features such as grouping, solo-in-place, and copy/paste
- Write-protect each of the 4 presets
- Works with iOS ‘Split View’ for running multiple apps side-by-side
