Extron Panel Audio

Audio on the Extron panel is controlled using the main volume knob and the feedback lights indicate the current volume level.  The source for the audio is selected using one of the input buttons.  The audio will only be routed if the desired input is illuminated and the system is powered on.  The currently selected source will also be displayed by the projector.

Troubleshooting Audio

If you are experiencing audio issues in a Standard Extron Room, please use the following steps to resolve your issue.  Once the audio is working, you may stop troubleshooting and do not need to complete every step.

  1. Make sure the Extron system is on.  This is indicated by the illuminated ON button on the panel.  If the ON button is flashing, please wait for the system startup to complete (may take up to 60 seconds).
  2. Select the desired input for the audio source.  If the input is already illuminated, press a different input, wait a second, then switch back to your desired input.  Occasionally these systems get "stuck" on a particular input and need to be rerouted.
    1. If the audio source (PC, laptop, Blu-ray player) is not also displayed on the projector, the system is routing a different source. 
  3. Turn the volume knob up until the indicator lights illuminate red, then turn the volume back down to 50-75%.  The amplifiers in our Extron systems have a power-saving mode and will not turn on until a sufficiently loud signal is detected.  Turing the volume all the way up and then back to a more reasonable level will ensure the amplifier is powered on.
  4. Next check the volume levels on the source.  If you are using the podium computer or a personal device, make sure the system audio is not muted and turned all the way up.  If you are using a media player,  such as YouTube, make sure the volume level on the player is turned up all the way as well.
  5. If there is still no audio coming from the speakers, there a few more steps to take to resolve the issue:
    1. Check to see if the correct audio output is selected. 
      1. If you are using a Windows computer:
        1. Right-click the sound icon  in the taskbar and select Open Sound settings.
        2. Select the device you want to use in the list of sound output devices.
      2. If you are using an Apple computer:

        1. On your Mac, choose Apple menu  > System Preferences, click Sound, then click Output.

        2. Select the device you want to use in the list of sound output devices.

    2. Check the audio cable connections at the source device.  For a laptop, make sure the HDMI or Auxiliary audio cable is securely attached to the device.  For the podium PC, check that the audio and video cables are securely connected.
  6. If there is audio present but the sound is muffled or quiet, make sure the volume is turned all the way up on the audio player, the source device, and the Extron panel, in that order.
  7. If you are still experiencing audio issues, please contact an Academic Support Technician at 255-HELP (x4357).
