== How to Interpret the LEDs Near the Channel 1 and Channel 2 Inputs ==

There are two LEDs on the PS1 powerstand -- one for Channel 1 and another for Channel 2.

The ~~channel input LED works~~ in ~~concert with~~ the ~~Trim Control located nearby~~. The trim ~~control adjustst~~ the amount of gain in the preamplifier.

The LEDs indicate when the signal level '''in the input preamplifier''' reaches certain important thresholds. The '''trim controls''' located near the LEDs adjusts the amount of gain in the preamplifier.

The LEDs ~~is activated when the signal level at a point just~~ '''~~after the preamplifier~~''' ~~reaches certain thresholds~~.

:The LEDs turn from '''off -> green''' when the signal level exceeds a small amount.

:The LEDs turn from '''~~off to~~ green''' when ~~there~~'s ~~more than~~ a ~~little bit of signal~~.

:The LEDs turn from '''green -> red''' when at the signal reaches a level that's about 10 dB below a level that would clip the preamp and cause objectionable distortion.

~~:The LEDs turn from~~ '''~~green to red~~''' ~~when at~~ the ~~signal reaches~~ a level ~~that's about 10 dB below a level that would clip~~ the ~~preamp~~ and ~~cause objectionable distortion~~.

'''When the LED is off''' (but you are playing an instrument you think is connected to the PS1 or singing/talking into a microphone you think is connected: Increase the level of the trim control. If the LED still does not turn green or red, check instrument/mic and cables to the PS1.

~~'''When the LED is off but you are playing or singing''': You are not delivering a signal to the input and/or the trim control is too low.~~

'''When you see green only''': This indicates that there's some signal in the channel but not enough. While singing or playing as loud as you plan to in the performance, increase the trim level until the LED is only flickering red. This is the optimal gain.

'''When you see green only''': This indicates that there's some signal in the channel. ~~Singing~~ or playing as loud as you plan to in performance, increase the trim level until the LED is only flickering red. This is the optimal gain.

'''When you see red most of the time''': Descrease the trim level until you see only flickering red. This is the optimal gain.
