== Model II / Compact / F1 ==

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.

=== 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 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.

Line 63:

# Adjust the input gain of the individual channel. These channels do not have indicator LEDs but are optimized for 0dB line level signals, such as from an effects device, mixer or CD player.

# As above, the R1 Remote Control MASTER knob is the last stage of gain. This knob gives you control over all 4 channels of the PS1 Power Stand.
