Test procedure Analog input
Power up VUPPM Compact with the bottom of case removed so you have access to the 4 trimpots.
Press Meter Mode and Peak Mode together to go into led test mode. This shows all green then all orange and then all red.
Press peak reset to set brightness level to LOW, MEDIUM, HIGH.
Press either Meter Mode and Peak Mode to leave led test mode.
Send in 1k tone at 0dFS or +18dBu to 500 Input for left and Output for right.
Set mode to VUPPM mode RED PPM with GREEN VU over the top.
Adjust Left and Right level trimpots so left and right 40th red led just light.
Adjust Left and Right VU/PPM trimpots so left and right green led just light. (40th led may make yellow depending on peak mode)

I couldn't get the Compact Analog PCB screwed on the Main PCB because of C14 touching the DETN01L-12.
So I just moved C14 to the other side of the main PCB: problem solved. If you plan on doing that, just be aware of the polarity!
