Troubleshooting

A microphone is not producing a signal​

  1. If the microphone requires phantom power, confirm that the channel’s +48V switch is on.
  2. Try another XLR cable.
  3. Check the microphone connection and all connections from ASP800 to the interface or recorder.
  4. Confirm that the correct destination input is selected and metered.

ASP800 will not lock to an external clock, or the audio clicks and pops​

  1. Press SAMPLE RATE until the LOCK switch flashes green. This selects external-clock mode.
  2. Confirm that the master clock source is valid and set to the required sample rate.
  3. Connect the master clock to the ASP800 BNC input with a 75 Ω BNC coaxial cable.
  4. A valid clock should make the green LOCK indicator illuminate steadily.
  5. Ensure there is only one clock master in the system.
  6. Check master/slave configuration, clock cabling and termination. Engage the ASP800 75 Ω termination only when it is the only or final device in the word-clock chain.
