  If effects are not being applied on your Yamaha Music Mixer, check that the [FX] knobs for each channel are at suitable levels. Ensure the [ON] button for [FX RTN] is activated. Verify the [PARAMETER] knob and [FX RTN] fader are correctly adjusted. Confirm the [FX RTN] bus assign switch is properly set. If external effects are connected to the [SEND(AUX1 – 4)] jacks, make sure the [AUX1 – 4] knobs for [SEND MASTER] are appropriately set. Check that the power of that device is turned on.

Why are left and right levels different on my Yamaha Music Mixer?
- C
  Cheryl MartinezSep 10, 2025
  If the left and right levels are different for a stereo signal input on your Yamaha Music Mixer, first ensure that [PAN] is set to the center. If it is, try reversing the left and right input connections. If the low volume switches sides after swapping connections, the issue is with the instrument or device sending the signal. Also, check that you're using the same type of cable for both left and right inputs, as cables with built-in resistors can reduce the signal. Check that the power of that device is turned on.

Reduce effect or compressor levels using the [FX] knob, [FX RTN] fader, [FX RTN LEVEL] knob, and [COMP] knob. Also, avoid connecting to both XLR and phone jacks or phone and RCA pin jacks simultaneously on an input channel. Verify the microphone is connected to the correct [MIC] or [MIC/LINE] jack.
