For a short cable, the 20k resistor is probably not needed, as the input you're connecting to is somewhere between 600 ohms (unlikely these days) and 10k ohms. But it certainly doesn't hurt to shoehorn one in. And if you don't have 470 ohm resistors, any pairs up to 1.5k ohms each or even more will work. 470 ohm appears optimal, especially if you're feeding a relatively low impedance input. Most inputs these days will be quite a bit higher. And the resistor tolerance is not of much consequence. For 1/8 watt resistors, they are probably all 1% anyway. You can measure them with a meter to make sure they're close to each other. The resistor power rating doesn't matter; the only consequence is that they get bigger as the power rating goes up.

It's the mirror side from what you show before, but since it's easier to follow diagrams people may indeed connect pin 2 to 3 !

You should be using 5-minute epoxy applied to the contacts on the TRS jack with a toothpick, and loctite blue on the screw threads. There should be one smaller piece of heat-shrink on the cable as a strain relief, and one larger one over the housing if desired.

I understand why you tie the left and right (T & R) input signals together using 470 ohm resistors. However, as I am not using an XLR plug for the output connector do I still need to use the 20K ohm resistor between the summed signal and the sleeve on the mono jack output? Many thanks.

There are some DI boxes and passive mixers around, e.g. Rolls DB226 (which sums up stereo RCA signal to a balanced mono signal). I use it for my projects.

Can I just ask what the purpose of the 20k resistor is because I have seen others do this with a mini jack to a regular jack and in those examples the resistor you are using is not part of the equation yet the diagrams otherwise remain the same. I assume it has some function related to grounding if I understand the diagram you linked to correctly. NB: Forgive me if I have completely misinterpreted something.

The reason for your issue is that XLR mics give a MONO balanced signal, which has the normal signal AND an inverted copy of the same signal. Wiring this straight into a STEREO 3.5mm plug will put the normal signal in the left channel and the inverted signal on the right channel. The cable I just described will wire the normal signal into both the left and right channels of the 3.5mm TRS, eliminating this problem.
