System Notes

General​

  • Do not share the HBUS or Mixer connections with any other network devices.
    • High-quality, low-latency audio requires a constant stream of large amounts of data; therefore other devices on the same network could compromise the quality of the audio.
  • The system will not link at 10/100 Mbps, as it is designed to work at gigabit speeds. This includes the HBUS input for connection to a PC, tablet, or smartphone for app functionality.
  • The system is designed to work with suitable unshielded CAT6 cable complying with the National authorities (cable with an outer jacket or sleeving rated VW-1 or better). Note, using low-quality cables may result in the Mixers refusing to link with the Hub.
  • Do not use shielded CAT6 cables which can cause ground-loops.
  • Unshielded CAT6 cables, used for HBUS or going to PRO Mixers, can be run 100 meters (328 feet) with no problems. Note, due to advanced internal termination techniques, cables used with the PRO series can be run up to 500 feet in ideal conditions (one piece of solid conductor CAT6 with no breaks or couplings). Utilizing proper punch-down and the correct RJ-45 connectors is key. The more breaks/connections/couplings in a cable run, the more limited this distance will be. Poor quality cabling will also limit the maximum distance. Running unshielded CAT6 cables alongside AC cables, fluorescent light fixtures, or computer network wiring will also limit the maximum distance. It is always preferred to run the Hear Back PRO CAT6 cabling by itself, away from other cabling. ALL cabling should be electrically tested before use. Contact an expert network professional for assistance with wiring installation.
  • Don't use those old, gray, flat telephone cables (ISDN cables) as those are not gigabit Ethernet cables.
  • The ground and power rails of the Mixer are totally isolated from the Hub, meaning no more ground loops to worry about.
  • The Mixer faceplate can be labeled by using a dry erase marker (simply wipe off), grease pens (erase with pencil eraser), label maker, by writing on a removable paper overlay, or electronically labeled with the optional PRO Digital Overlay. Please note that using permanent markers results in permanent labels!
