Avoiding extraneous noise
If audio cables are connected to AUDIO INPUTS
1–2, any noise carried by the cables will enter into
the M3 mixer structure. Similarly, the S/P DIF
input may carry noise from external devices. This
may include hiss, hum, and other audio noise.
To avoid noise from unused audio inputs, either:
• Set the input’s Level to 0
or
• Set all of the bus assignments to Off, including Bus
Select (IFX/Indiv. Out Assign) , AUX Bus, and FX
Control Bus
If no audio cables are connected to AUDIO INPUTS
1–2, the input signals are forced to zero, preventing
any additional noise.
If you want to save the edited settings in the M3,
you must write them. Use the Global mode menu
command Write Global Setting to do this.
3. If you want to use the Global mode Input settings
in the other modes, check the “Use Global
Setting” option.
If you want to make independent settings for
Programs, Combinations, and Songs, uncheck this
setting.
