Initial Yamaha Mixer Settings

Resetting the knobs per channel



  1. Make sure the red master knob is all the way down.


  2. Turn off the feedback suppressor for testing. The last thing we do will be turning this back on to catchanything our manual settings miss.


  3. In the level meter section, set the button so meters monitor LR output (button raised), not Aux output.


Connecting the Mixer to Other Gear

  1. Before connecting speakers, confirm audio is reaching the interface and Reaper. Speak into a mic and turn up the channel level knob until the green LED lights on input. Then turn up the red master level and confirm LR LEDs show output (with LR meter mode selected).
  2. Connect the NL4 outputs to the speakers.

Now do the test
