Am I correct here: I’m building an audio cable for the K3S — 3-pin XLR from the mich to the 8-pin K3S input (pin diagram on page 13 of the Owner’s manual). And here’s a Wiki on the XLR pins: https://en.wikipedia.org/wiki/XLR_connector XLR pin #1 (ground) to K3S 8-pin #7 and #8, both ground.
First, the correct words are SHIELD and SHIELDING ENCLOSURE, not "ground." For a dynamic mic, pin 1 to the shielding enclosure, pin 2 is mic "high," pin 3 is mic return.
The connector shell should be grounded also for best RF protection, yes?
NO, an the shell of an cable-mounted XLR should NOT be connected to anything. The shell of ALL connectors built into equipment SHOULD be bonded to the shielding enclosure.
