Patch bay question - tapping TWO signals?

The simplest answer is to use a splitter patch cable , basically 1trs wired in parallel to 2 more trs , Possibly with the earth disconnected on one of the destination trs plugs , to avoid possible ground loops .

I might also add that the question is slightly misleading as you're not trying to tap 2 source signals as the query suggests but splitting 1 signal to 2 destinations ,
If you were trying to tap 2 sources to one destination , you'd need a summing cable with some resistors in it , rather than a splitter .....

.....or back in the old days......

We called this a "mult" and it was in the patchbay. I still use them and have two in my existing bay now.

If you have the space, do a full normal on two adjacent pairs (or columns), and then connect those two rows in the back of the bay. Patch your source to the uppermost left member of the mult, and you can grab that signal and patch "out" from the remaining three......

....it makes sense in my head.......

From a logical sense it looks something like this (the horizontal lines are a patch in the rear of the bay, the vertical are full normals):

Ah yes. I am not trying to tap different sources to one destination. I am in fact trying to tap the same source to two (or more) destinations.

I am not quite sure I follow. Would you mind elaborating? Thank you

I'm not sure if I can....lol - but I'll try.

If you take two patchpoints and configure them as full normals, they remain connected whether you have a cable plugged into the top, bottom, or both of the pair (a pair is usually vertically aligned). You set up two pairs like that which are next to each other, and then connect them at the back of the bay so now all 4 patch points are always connected to each other.

I'm not sure that helped.....sorry.

Thanks, it did help.
The neutrik bay I use is half-normalled, but I did set up a pair.

Patchbay module 9-10:

Module 9 is half-normalled (grey jack at the bottom front)
Module 10 is turned around (grey jack at the top back).

Then at 9 the bottom back is connected to bottom back 10, thus giving me both jacks at the front of 10 with the same signal as 9.

Now I have the preamp signal at 1, half-normalled to my DAW.
Then I patch 1 to 9, which feeds the signal to 10.
10 has two destination: cue mix and tape machine.

Works perfectly.
I asked a tech and he said that I had to repeat this another 5-6 times before noticeably degrading the signal.
