=== 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 [[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. | |||
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. | |||
