PRELIMINARY DATA

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 e ver need.

Introducing the latest addition to the Hear T echnologies family – Hear Back PRO.

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: Hub & Mixers

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 cable. And with the built-in HBus In/Out ports, multiple Hubs can be daisy-chained
together, allowing for truly unlimited system expansion.

The standard Hub (included in the “4-pack”) comes pre-loaded with one Network Card and
two 8-channel Analog Input Cards which can accept input signals from an audio mixer via
auxiliary, matrix, monitor, and/or direct outputs.

The Hear Back PRO boasts many key advantages, including:

• Side-mounted card slot on Mixer for
future expansion

• Large master knob controls overall
main mix, AUX, and intercom levels
independently

• Volume and panning control of all
16 channels

• Direct and immediate visual feedback of
all 16 channels

• Up to 8 pairs of stereo-linked channels

• Support for sampling rates up to 192 kHz

• Selectable XLR or 1/8” Mixer AUX input

• 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

• Modular I/O Hub card system lets you
customize the system to match your
configuration, and can adapt to your needs

• Supports secondary power supply to
provide redundancy and power to up to
32 Mixers

• USB port on Hub makes updating firmware
for future features and upgrades a simple
drag-and-drop operation

• Status indicating logos on Hub and Mixers
make it easy to detect and diagnose
problems, should they arise

• Write session info and channel settings
on storable Mixer overlays for an unlimited
number of presets

– Instantly store and recall presets from

memory with the push of a button

– Most recent configuration is saved, even

after power-down
