I've got something puzzling - we have an Sq7 - we have snake that runs to the Pulpit are various areas around -
I plug in a Radial Direct Box  to any channel on the snake and it doesn't work - I plug the same box into the Mixer
directly and it works.

I tried 5 direct boxes - 3 Radials (passive) and 2 Behringers (passive) and none worked. I tried a Whirlwind EDB-1 Direct Box and it works.

I'm mystified.

check for pin one continuity...

It wouldn't work at the board if that was the case - and a microphone plugged into the XLR works fine - not to mention 5 commonly used Direct Boxes and 6th one worked.
I'm telling you - this has me puzzeled.

I actually like puzzles like this!

Same cable for all the testing, even with the mic?
What model are the other DI's?
I assume the snake is a multipair copper analog all the way back to the board.

Funny that the very budget Whirlwind did work!

Pin one shouldn't matter on a passive DI provided the cable is wired correctly.

A few questions:
1) New snake, or been in the hall for years?
2) Commercially made snake, or wired by a congregation member with an EE?
3) Do/have microphones worked on this snake in the past?
3a) If "yes", dynamic, condenser, or both?
4) Does "doesn't work" mean no sound, or weak and "thin" sound?
5) What was your test signal for the DI's?
6) Is the snake XLR-XLR, or one of those newfangled analog audio over RJ45 breakout dealies?

2 - I sense a bit of sarcasm between the words.

6 - I'm too oldfangled to buy into those breakout dealies.

If the snake has pin one open, phantom power would not work... Is the mic that works dynamic, or using phantom power?

Another fairly obvious test, do they work using a single known good XLR cable? Of course they will, but this just confirms that the snake is funny.

The Microphones were both Dynamic and a condenser - I was thinking the same thing - all the DIs were passive so they ignore phantom power.

So just to be clear, a phantom powered mic does work, and passive DIs don't work? 

Did you try a known good single XLR cable?

Yes the Condenser and Dynamic Mics works - The Whirlwind Direct Box works - the Radial and Behringer DIs don't work - and I tried it on multiple sends in different zones -
the XLR was fine as it worked with the Condenser,Dynamic and Whirlwind DI.

I'm scratching my head over this - there seems to be no reason to it.
