If you get the chance to do them, would you kindly post them here? Thanks!
Sure, unless @Mitchco feels so inclined. :)

Hey @jtwrace, Hope you are well. I’m checking the gear around the Motu interface and came with an issue for the cables. For the mains, it is clear I can go from 6.35mm TRS to XLR. But from the analogue outputs to my subs. I read that Motu advices as follows:

Quarter-inch analog outputs are not cross-coupled. Therefore, when connecting them to an unbalanced input, use a TRS plug with the ring disconnected. Not floating the negative terminal will short it to the sleeve ground and cause distortion.

I have 2 SVS SB-1000 Pro, which I connect wirelessly with the SVS Soundpath Wireless Audio Adapter (it has a 3.5mm plug connection).

What I understand from Motu is that I need to use a Male TRS to a Male TS connection, but I don’t think this is standard. As I know that you have your subs connected to the Motu (probably not wireless), but what connection would you use?

thanks!

Yes, I do have all my subs direct to the Motu. I use TRS > RCA (FM8) or TRS > XLR (F18). In your case without the wireless connector, I'd use #5 as I highlighted. The wireless adapter is USB > 3.5mm. I don't see why you couldn't make a TRS > 3.5mm cable and try it. The only issue you might have is lag with the wireless signal. Also, since you have a cable to the wireless adapter near the sub, why not just plug in direct from the Motu since all levels are done from the Motu anyway. You will not use any of the SVS settings with AL.

Thanks @jtwrace . I will not use any of the dsp from the svs subs.I need to have a wireless signal to the subs.
So your suggestion is ti go 6.35mm TRS to 3.5mm TRS? Would that work?

Yes, TRS to 3.5mm if you must use the wireless box.

3.5mm comes standard TRS (when sourced from TRS). Shall I use that one or do I need to customize a TRS to TS cable in this case?
