Just buy stereo trs to dual mono ts (usually it has indication for left and right) so number 1 should work (as long as you don't buy insert cable, it looks the same but usually doesn't have left/right or white/red indicators).
Number 2 should also works perfectly, as far as I know it the PSM support unbalance and balanced input on 6.3" jack, though I have use number 1 with my PSM900 and doesn't have issue as long as you buy the right cable.

In regards to signal integrity I don't think there will be much differences as both are unbalanced. Correct me if I'm wrong

Thanks for the info. Wonder which input of the wireless Iíd plug the TRS into? Left, right or does it matter? Left is generally reserved for mono.
And I just noticed on Sweetwater website they have a converter available. 1/4Ē TS male to 1/4Ē TRS female. Canít attach photo itís to large but here are the specs:

NP2C-T10AA

2 pole 1/4" professional phone plug, built-in 1:10 transformer to convert balanced signals (TRS, mic) to unbalanced (TS, guitar) signals

If latency is important, then Sennheiser EW-D might be more interesting as it spec wise has lower latency than Shure (SLX-D vs EW-D) but going on QLX-D the difference is minimal and mostly depend on which mic you want to use. The Bluetooth implementation on Sennheiser is quite unique as you could use your phone to change setting on the transmitter directly if you want to, but seems to be intentionally limited as to not eat up the upper market of their series.

Personally based on your need, EW-D seems fit the bill as the apps help lifting coordination complication for up to 16 set while SLX-D you may need to connect each receiver with ethernet and pairing transmitter with IR. In my country at least the price is about the same for both.

Have both units. P16-M has one, 1/4Ē stereo headphones output and two, 1/4Ē TS outputs as the output options. Iíve been using the stereo out to earbuds as a wired connection but now want to use the wireless as a stereo mix. The PSM has two, 1/4Ē TRS inputs. What cable(s) do I use to connect this?

I understand exactly what TS and TRS cables are and how they function. And nobody even makes a TS>TRS cable because itís all unbalanced anyway so itís moot.

Some questions:
1. Should I use an all stereo Y cable from headphones out to the two TRS inputs of the PSM?
OR
2. Use two, TS cables from P16-M to the PSM?
3. Does it matter using TS cables when the PSM takes TRS?
4. Will both in 1 and 2 work the same no matter which way I decide to go?

I emailed Shure and received an answer to use two, TS cables but they did not elaborate vs using one TRS Y cable for the headphones out. Iím sure they are correct but wanted some opinions I guess. Iím concerned with signal to noise ratio using unbalanced cables of 30 ft run. Wondering if stereo would give me a better signal. Thanks in advance!

Title pretty much says it.  We have temps reaching into the 110 this weekend.  Wondering if I ought to pull my subs and tops into the house...  trailers are silver and white so more reflective than black anyway.

Iíve left cabs in trailers for 40 years in all kinds of weather. Never had an issue where they didnít work as expectedÖÖ.

Welcome to the forum! Thank you for actually reading the "real name" policy!

You said it yourself: the TRS headphone output is stereo. This means that Tip is "left audio hot", Ring is "right audio hot", and the Sleeve is both the "ground" and also the common audio signal return path. By definition, a stereo TRS connector carries two channels of unbalanced audio instead of a single channel of balanced audio.

Running a stereo signal into a balanced mono input is likely to do weird things (the most common "weird thing" is a sum of L and R but with the R polarity reversed, which has the effect of causing anything panned centre to disappear entirely); splitting a stereo signal and running it into two balanced mono inputs would do the same thing twice.

No problem

So are you in agreement with Shure then? Use two, TS cables out of P16-M to TRS inputs of PSM 300?

I have seen several band lives (Chevelle and Alter Bridge specifically) that invoke a really low "something", very sparingly in their show. Low enough in frequency to shake the venue. Does anyone know what that is? It is not kick, bass guitar, etc.  I is so low, it is not even a note, but when unleashed, your body shakes.

I want it!!! Probably can't afford it.

Thanks.

on A&H Dlives and Ilives  there's the hypabass plug in..love it for just that effect that you mentioned

I think the bigger challenge will be acquiring enough subs to have the " effect " have the effect you want.

Or the right subs....

Meyer VLFC's come to mind. Not cheap though  :o

I ran into a problem many years ago with what I believe was a cheapskate impedance balanced output. On a corporate talking head gig (some music playback for stingers and maybe a video or two) I was looking for a post fader aux output to feed some subwoofers at the other end of the snake. The Midas Venice had 2 aux outputs on XLRs that are supposed to be balanced and 2 "FX" aux sends on 1/4" TRS that are also supposed to be balanced. Since my XLR aux sends were already in use I used one of the "FX" sends with a TRS to XLR adaptor feeding through a 150'+ snake and into a DSP in the amp rack. It buzzed - badly enough that I needed a different solution. Switching the subwoofer send to one of the XLR "real" aux sends worked cleanly.

I believe (and I think professor Whitlock has basically said this) that it's the receiving end that does most of the heavy lifting. I'm not remembering now what model the DSP was but I suspect it was taking some shortcuts. In this situation, at least, the sending end made a difference.
Bill is now active over at GroupDIY where I'm a mod. I could ask him for you, but I already know the answer.  8)

 In a balanced interface everything matters wrt the impedance balance.
