I ended up cutting the trace and terminated it directly from the XLR to the edge connector, the Pin 2 pad on the PCB was shorted to ground somehow, weird.

VERY strange.

Hi there...
I just build a 511 VPR, I was wondering if there is any checking guide somewhere beforeI load any rack and having trouble!
there is also a way to check if each rack space work properly?
thanks

We always check the DC voltages before loading modules. Once those are verified we use a preamp or something to test each slot.

Ok I did it, each channel gave me between 15.5/16.5 VDC on pin 12 and same numbers but negative on pin 14.
I did it putting the common on pin 13 then switching the other cable on 12 or 14. I'm not sure if is the best way to do it but those thing freak me out. In fact I accidentally touch for an instant 13 and 14 on channel 4 and saw a little sparkle :-\. Then I checked the value and seems fine. I will wait before loading something on that channel ;D.

Thanks Alex

It will be fine. The main supply voltages are on a continuous PCB trace so that slot's supply voltage will be the same as all the rest. A direct short for a split second is not desirable but not the end of the world either.

Curious about users thoughts on the smps psu vs the linear floor box. Does it make a noticeable difference on pre’s or compressors? Anyone that’s actually tried both?
