On the {{Model II}}, the {{Compact}}, and the {{F1}} ~~the Trim (Model II) and~~ Volume (Compact/F1), these controls are actually trim controls. There is no master volume control later in the signal chain. The amps are running at full output. There is no need to "add a little extra" for headroom. If you do, you are unnecessarily amplifying noise (e.g. audible hiss/hum) during quiet moments, and raising the likelihood of distortion when you get loud.

=== All models except the ToneMatch Mixers ===

On the [[L1 Pro]], S1 Pro(+), {{Model II}}, the {{Compact}}, and the {{F1}}, Volume (Compact/F1), these controls are actually trim controls. The L1 Model II/L1 Model 1S have a trim control.

There is no master volume control later in the signal chain. The amps are running at full output. '''There is no need to "add a little extra" for headroom'''. If you do, you are unnecessarily amplifying noise (e.g. audible hiss/hum) during quiet moments and raising the likelihood of distortion when you get loud.

=== Setting the levels ===

For the ~~Model II~~ run the source at the highest output and set the ~~trim~~ so ~~that~~ you see solid green and occasional flickers of ~~yellow~~.

For the [[L1 Pro]], run the source at the highest output and set the volume so you see solid green and occasional flickers of red.

For the ~~Compact~~ run the source at the highest output and set the ~~volume~~ so that you see solid green, and ~~no red~~.

For the L1 Model II, run the source at the highest output and set the trim so that you see solid green and occasional flickers of yellow.

For the ~~F1 Model 812 or F1 Subwoofer~~ run the source at the highest output and set the volume so that you see solid green, and no red.

For the L1 Compact, run the source at the highest output and set the volume so that you see solid green, and no red.

For the F1 Model 812 or F1 Subwoofer, run the source at the highest output and set the volume so that you see solid green, and no red.
