Hear Back PRO System

This is it - the most comprehensive 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 is the last personal monitoring system you’ll ever need.

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 CAT6* cable. With the built-in HBUS In/ Out ports, multiple Hubs can be daisy-chained together, allowing for truly unlimited system expansion.

System Standouts

  • Modular I/O Hub card system allows for system customization
    • FW V5 and V6 allow two independent input sources simultaneously (e.g. Analog, Dante)
  • Large master knob controls overall main mix, AUX, and intercom levels independently
  • Volume and panning control of all channels
  • Direct and immediate visual feedback of all channels
    • Write session info and channel settings on storable Mixer overlays for an unlimited number of presets
    • Optional PRO Digital Overlay (available for FW V6) features OLED graphical displays for electronic channel labeling and Mixer status
    • Instantly store and recall presets from memory with the push of a button
    • Most recent configuration is saved, even after power-down
  • Support for sampling rates up to 192 kHz
  • Selectable XLR or 1/8" Mixer AUX input on PRO Mixer
  • Built-in intercom broadcasts the AUX source (mic, MP3 player, click, etc.)
  • Intercom auto adjusts its own level so even the quietest message never goes unheard
  • Supports secondary power supply providing redundancy and power for up to 32 Mixers per Hub
  • USB port on Hub makes updating firmware for future features and upgrades a simple drag-and-drop operation
  • HBUS In/Out connections allow daisy-chaining Hubs
  • Side-mounted card slot on Mixer for future expansion
  • Status indicating logos on Hub and Mixers make it easy to detect and diagnose problems, should they arise

The Hear Back PRO system is available in a Four Pack plus an Overlay Upgrade, as well as offering Mixers and Hubs separately.

Cabling, Mixers and HBUS

CAT6*** cables used for Mixers or for HBUS can be run up to 500 feet in ideal conditions (one piece of solid conductor CAT6 with no breaks or couplings). The more breaks/connections/couplings in a cable run, the more limited this distance will be. Poor quality cabling will also limit the maximum distance.

Note: 0 dBu = 0.775 Vrms. Specifications and features subject to change without notice.

**Hub is capable of powering up to 32 Mixers with an additional power supply.

***Cable complying with the National authorities (cable with an outer jacket or sleeving rated VW-1 or better).

PRO Connect

Description

The new PRO Connect application combines the features of multiple legacy apps and tools while adding new functionality. PRO Connect provides a web-based interface to update, configure, and control your PRO Mixers and PRO Hubs. It is the perfect digital companion to our extraordinary flagship personal monitoring system.

Features

  • Matrix Mixing & Submixing: Create different layouts for each musician by mapping audio sources to knobs on a per-mixer basis.
  • Multiple Mobile Users: PRO Connect provides a mobile, browser-based interface to allow multiple users to control their mix. Just connect to the same Wi-Fi network and pull up the app in your device’s browser.
  • Session Management: Save settings for all Mixers from a session or band and recall those settings through a simple interface.
  • All-in-one Updater: We enabled firmware updates for the PRO Hub via Ethernet, wrapped in the Mixer update utility, and brought in new tools such as the Mixer Digital Overlay updater. PRO Connect provides new online versions automatically.
  • Visual Hub Configuration Wizard: PRO Connect provides a new visual tool to more easily configure your Hub. Add virtual cards to a virtual Hub to match your setup and send settings to the Hub automatically over Ethernet.
  • Channel and Mixer Naming: You can link stereo channels, name Mixers, and name individual channels for display on your Mixer Digital Overlays.
  • Channel Soloing: Solo a channel with the click of a button to isolate it from the rest of the mix.
  • Mixer Grouping/Mirroring: Group PRO Mixers to activate mirroring, a special mode that keeps all Mixers within a group synched. Change your mix on one Mixer and it reflects on the other Mixers.
  • Improved Metering: The Hear Back PRO Hub page includes an improved, more accurate, input channel meter display.
  • Compressor/Limiter: Adjust threshold, attack, and release of the onboard limiter of each mixer.
