Direct Boxes not working through Snake to SQ7

The DI boxes all work elsewhere?

I tried a different XLR - but the current XLR is definitely good - the DI boxes when plugged direct into the mixer
work well -

Mike Caldwell:
Is the snake a "factory" built snake.
In installations many times the snake is built/terminated on site or at least one
end of it......and I have seen some crap jobs attempting to do that!
How did you test the snake cable channels.

What comes out of the XLR of a passive direct box is not much different than and SM58.

And to double check is this an old fashioned copper snake cable or an Allen Heath remote stage box that goes with your SQ7 mixer?

Post some pictures of the snake, and pictures of some of the solder connections at each end.

As Ike mentioned, there is working and then working correctly. With a mic plugged into the snake and then plugged into the mixer......same input, same settings does it sound the same? 

John Roberts {JR}:
OK.. If it behaves properly with a separate known good XLR cable, but not with the installed snake, something is wrong with the installed snake.

The next troubleshooting step is to test all the snake channels to see if they all behave the same.

Just had one of my maintenance tech come in with an "impossible scenario"-happened to be vacuum lines in his case.  Every time (every single time) I have run into an "impossible situation" while troubleshooting I eventually figured out I had assumed something-either on purpose or accidentally as an oversight.

What I would do?  Take paper or spreadsheet and make a matrix with devices on one axis and tests on another and write down what I am testing and results.  You have a lot of iterations going on to see the complete picture in your head.  Just my 2 cents.

They just need to unplug it and let it reboot.  ;)
