Question on tt-96 point patch bay

[deepershadepro]

on a solder pin style 96 point tt patchbay, I can't find any info on tying the shields (pin 1) together from top row to bottom row in a half-normal configuration.(see illustration) In a multitrack out to channel/line in configuration without breaking normal......this illustration looks like it is lifting the shield without any breaking of the normal. wouldn't you just solder a 20 gauge jumper wire from top pin1 to bottom pin 1 to carry the shield when the normal is not broken...just like you have to with the ring and tip pins to create a half-normal circuit? I understand that the shield will be carried when you break normal with a patch cable inserted. any ideas ?

Hi
As shown the grounds are not connected with no patch cord in place. This would then rely on existing grounds between the various bits of kit.
Some systems have ALL shields connected on the patch and assuming the majority of sources / destinations are balanced then it may be the best way to go. You have to decide whether you want shields on outputs, inputs or both. In terms of preparation it is possibly easier to bus all the grounds and chop them out if you have a problem. With a balanced / unbalanced setup there is no 'best' way.
