Steps

After each step, check that the system is working properly to avoid unnecessary troubleshooting
  1. Confirm power is on for all components
    1. The rack power switch should be on
    2. Older racks may have a horizontal power strip that must also be on
    3. Verify individual components are on with their LCD screens or power LEDs
  2. With a source playing, test that the source device is getting signal into the mixer
    1. Adjust the Gain knob on the channel the source is plugged into and verify the Green SIGNAL LED lights up and the PEAK LED does not light up.

    2. Press the HOME (METER) button until the CH1-32 tab is selected on the screen

    3. On the screen, the METER MODE should be set to LEVEL and POSITION should be set to PRE FADER. Use the arrow pad and dial to select these settings.

    4. Verify signal bars show on the channel being tested.
  3. If no signal is showing:
    1. Check that the source is playing and is plugged in
    2. Test the source output by measuring AC voltage between pins 2 and 3 of the XLR or tip and sleeve of the 1/4" TRS connector and check the wiring or try a different source

    3. Check the terminal blocks on the BOP In/Out cards in the rack
    4. Check the output of the source device
  4. Make sure the MONITOR/2TR IN button is NOT depressed

  5. Verify the channel is being sent to the STEREO bus
    1. Press the PAN/ROUTING button until the ROUT1-16 tab is selected on the screen.  Verify that the S button is selected on screen for the channel being tested. This allows it to send to the STEREO slider.

    2. Use the arrows and enter button to enable/select the S button if needed.
  6. Test the output meters
    1. Make sure all sliders are at a safe low level
    2. Verify the ON buttons for the channel being tested and the STEREO slider are on and their LED is lit up
    3. Verify no SOLO buttons are illuminated by pressing the CLEAR solo button above the control dial

    4. Set the STEREO slider at 0 and slowly bring up the channel being tested.  The signal should be visible on the main output meter.
