Hear Back Pro Hub Mainframe Expand

Hear Back PRO Hub Mainframe Only
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.

ADAT card
Placeholder imageAllows HB PRO Hub to communicate with audio equipment via ADAT protocol.

  • Simultaneously sends and receives 16 channels of digital audio
  • Backwards compatible with the original 8-channel Hear Back system
  • (2) optical ADAT TOS-Link inputs, (2) optical ADAT TOS-Link outputs, and (2) RJ45 HearBus outputs (for connecting to the original Hear Back system)
  • Supports and automatically locks on to sampling rates of 44.1kHz and 48kHz
  • Automatic sampling rate down-conversion is applied on the ADAT and HearBus outputs when the system is running at sampling rates over 48kHz
  • (2) cards can be populated per Hub to allow A/B input switching between (2) banks of 16 channels
  • Up to (4) cards can be populated to allow A/B input switching as well as a second set of dedicatedADAT outputs

AES/EBU card
Placeholder imageAllows HB PRO Hub to communicate with pro audio equipment using multi-channel AES/EBU protocol.

  • Tascam DA-88-style pin-out on a DB25 connector for inputting or outputting 16 channels of digital audio
  • Jumper settings allow the user to choose whether the card is 16 inputs or 16 outputs
  • Supports and automatically locks onto sampling rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz
  • DB25 to (8) XLR (each AES/EBU XLR connector supports 2 channels of digital audio) break-out cable is sold separately, unless the AES/EBU card is purchased as part of the Hear Back PRO Four Pack
  • (2) cards can be populated per Hub to allow A/B input switching between (2) banks of 16 channels
  • Up to (4) cards can be populated to allow A/B input switching as well as dedicated AES/EBU outputs

Dante card
Placeholder imageAllows HB PRO Hub to communicate with any audio equipment using Dante protocol.

  • Connects 16 channels of simultaneous audio input and output with other Dante-enabled equipment using a standard Ethernet network connection
  • Supports sampling rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz
  • (2) cards can be populated per Hub to allow A/B input switching between (2) banks of 16 channels
  • Up to (4) cards can be populated to allow A/B input switching as well as a second set of dedicated Dante outputs

Waves SoundGrid card
Placeholder imageAllows HB PRO Hub to communicate with any pro audio equipment that uses Waves SoundGrid. Our partnership with Waves makes it easy to directly connect the Hear Back PRO system to other high-end audio equipment (including directly out of a PC or Mac using only its Ethernet port).

  • Connects 16 channels of simultaneous audio input and output with other SoundGrid enabled equipment using a standard Ethernet network connection
  • Supports sampling rates of 44.1kHz, 48kHz, 88.2kHz, and 96kHz
