The Hear Back PRO system is a testament to modularity and scalability, with a design that's both intuitive and infinitely expandable. It's the perfect choice for those seeking a digital solution that simplifies the personal mixing process without sacrificing performance. The system's ease of use means that regardless of your experience with personal monitor mixers, achieving the ideal mix is straightforward and efficient.

At the heart of the system lies the Pro Hub Mainframe, a robust and versatile unit that forms the foundation of the Hear Back PRO system. The Hub is equipped with four card slots, allowing for a customizable configuration of input and output cards to precisely meet your audio requirements. The inclusion of the Dante Card elevates the system's capabilities, enabling seamless integration with other Dante-enabled devices and networks for remote control and monitoring.

Each Pro Hub can power and send signals to up to 32 Mixers, with each connection running over a single standard Cat5E/6 cable, ensuring a clean and organized setup. The built-in HBus In/Out ports facilitate the daisy-chaining of multiple Hubs, paving the way for system expansion without limits.

The PRO Mixers are the performers' interface to their own personal soundscapes, with the latest V5 Firmware offering an impressive array of features. Musicians can now route, assign, and submix up to 128 channels, ensuring that each performer's mix is tailored to their individual needs. The V5 Firmware also introduces the ability to submix up to 16 stereo channels on each of the 16 knobs per Mixer, providing extensive control over audio channels.

Key features of the system include panning width and stereo placement, solo in place, multiple intercom capabilities, and signal present indication on all channels. The grouping function synchronizes settings across multiple Mixers, while the iOS App offers additional ease of use with remote control capabilities.

The Hear Back PRO Mixers boast high-fidelity 24-bit Delta-Sigma D/A and A/D converters, ensuring pristine audio quality. With up to 4 recallable presets, performers can quickly switch between their preferred settings. The intercom feature facilitates communication among up to four users with Hear Back PRO Mixers, enhancing coordination during performances.

The system's flexibility extends to its connectivity options, with 1/8" and 1/4" headphone outputs delivering ample power, balanced mono/stereo line-level outputs, and a variety of input options including selectable AUX inputs and a microphone input for ambient sound capture or intercom use.

The Hear Back PRO Hub Mainframe and Mixers are designed with the future in mind, supporting multiple sample rates and offering minimal system latency. The Dante card and Network Card ensure that the system is ready for the most demanding professional audio setups, making the Hear Back PRO 4-Pack Personal Mixing System the choice for those who demand the best in personal audio mixing solutions.
