NHB32-C Network Hub and Bridge

32-channel Digital Audio interfacing with CobraNet™ Devices

32 In/32 Out Audio and Control Interface The NHB32-C is a 32 input/32 output channel interface unit for CobraNet™ and AES/EBU connections. Use the NHB32-C to transfer control signals for the ACU16-C amp control unit, MIDI devices, or remote head amplifier (AD8HR).* * Only one control type can be used at a time. About CobraNet™ There is a growing need for large-scale audio systems, and with it the need for advanced networking technologies that can distribute high-quality audio quickly and reliably throughout large venues or open facilities with fully integrated control. CobraNet™ is a sophisticated technology that enables transfer of multiple audio and control channels via Ethernet cable. As an integrated system, CobraNet allows digital data to be carried up to 100 meters* from one port to another device by common CAT-5/100Base-TX cabling, or up to 2 kilometers by optical fiber. It is fast, with constant 5.33ms latency**; it is reliable, thanks to built-in redundant systems; and, with the standard cabling and connections, it is remarkably easy to use and economical. * The actual maximum length of cables may differ depending on the quality of the Ethernet equipment or the particular settings used.** Low latency mode of CobraNet™ is now supported, which enables users to choose from 5.33ms, 2.67ms and 1.33ms.

NHB32-C Network Hub and Bridge

A 32-channel AES/EBU and CobraNet™ interface that facilitates construction of up to 64-channel audio and control networks with a LAN infrastructure.

  • A single NHB32-C unit can support up to 32-channels of digital audio I/O, and one control signal I/O.
  • Four separate 8-channel AES/EBU input/output terminals.
  • CobraNet™ transfers high-quality 20-bit or 24-bit 48 kHz digital audio over four bundle paths in real time.
  • MIDI, head amp remote (AD8HR, AD824) and amplifier control.
  • NetworkAmp Manager software allows central control of both audio and control signals.
  • Up to eight NHB32-C units can be networked, with each unit transferring and receiving four bundles, and 64 channels of digital audio can be received from any ACU16-C or NHB32-C on the network via CobraNet™.
  • A networked system with ACU16-C and NHB32-C units is capable of handling up to 64 channels of digital audio.
  • Multicast and unicast modes can be used in combination to optimize bandwidth.
  • Primary and secondary CobraNet™ ports are built-in, providing a redundant network for reliable operation.
