Troubleshooting

note

The HearBus and Mixer outputs contain high speed digital audio and should be treated as a transmission line. DO NOT "Y" these connections because the terminated controlled impedance will be comprised. The HearBus and Mixer outputs operate at 12.28 MHz.

DO NOT PLUG HUB AC POWER into a GFI receptacle.

No Signal​

  • Verify power is on.
  • Check input connections and input selector switch.
  • Verify the Hub and Mixers have green clock status indications.
  • Check output devices, headphones, wireless transmitter/receiver, monitor amplifiers, etc.

When I connect a line level device to the Mixer line outputs, I hear a buzz.​

  • Wire TRS outputs using only black (ring - ) and red (tip +) wires.
  • Disconnect shield at the Mixer and terminate at receiving end only.
  • For unbalanced outputs wire the Black (ring - ) to the receiving end sleeve and tie the shield at the receiving end only. Connect the tip (+ red) to the tip at the receiving end.

I have a clock signal at the Hub, but nothing at the Mixer.​

  • Isolate the problem as follows:
    • Check CAT5e/6 cable or try another cable.
    • Try another Mixer output port on the Hub.
    • Try another Mixer.
  • Verify the source (Mixer, DAW, etc.) has these outputs panned hard left and right. The pan control of the source determines the stereo spread.

The headphone amplifier fault indicator is on.​

  • The fault indicator indicates either a short circuit or excessive load.

I need more mixes.​

  • Connect the stereo mix (channels 1&2) with the FOH or control room mix across several Hubs (as many as desired) then provide the "more me" sectional mixes to channel 3-8 on each Hub until the desired number of mix's are met.

The fan does not operate.​

  • The fan only runs when power supply temperature reaches 60° C or 140° F.
