Hear Back PRO Personal Mixing System – Analog Input

Hear Back PRO Personal Mixing System

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).

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.

New V6 Features:

• PRO Digital Overlay compatibility
• Allows 32 channel digital input cards (e.g. Dante, Waves, MADI)
• Route-Assign-Submix up to 128 channels
• Submix up to 16 stereo channels on each of the 16 knobs per Mixer

• 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 and a wireless access point connection for use with the PRO’s iOS App
• Side-mounted card slot on Mixer for future expansion
