== L1 Pro / Model II / Compact / F1 ==

On the {{L1 Pro}}, {{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.

=== Setting the levels ===

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 [[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 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.
