Title: Best way to solder a TRS to dual TS cable?
Post by: Tuxedo3 on April 05, 2016, 05:24:44 PM
Hey guys, I'm setting up a pedalboard for a friend who has an H9, Timeline, and Bigsky. We're using a switcher so he'd like to run those pedals in 2 stereo TS cables each, down to a single TRS cable so the switcher can control it. The issue i'm having is that we're using Switchcraft right angle plugs and Mogami 2524 cable which is super thick, there's pretty much no way I'll get two of those cables in the shielding for the TRS. Any fixes for that?

Welcome! Running 2 cables into 1 plug is probably going to mean using small diameter cable. George L's is good, low capacitance-per-foot cable, and is pretty skinny stuff. Even though it's generally used with solderless connectors, it solders like any other cable. Or you could just use RG-174 or something similar. Neither of those say Mogami on the side though. :)

i Bought some Teflon/Kapton insulated coax with a very small diameter.

He's lots of different ones listed, (Teflon/Kapton's very stiff), Teflon would be fine.

Mogami 2319 might work.

Build a splitter box instead, imho easier, cheaper, more reliable

First off, thanks for the warm welcome guys. I appreciate it.

I'll totally research this a bit because I know GL's have a great rep.

Do you know if he sells it in black anywhere? We're looking to keep this as close to invisible as we can. I like the idea though.

I was thinking that same thing, I guess I could measure the opening and take a look at the diameter of the 2319 and see if two would fit in there.

Could you explain a little bit about what this is?

Sure, it's just an enclosure with a trs jack that connects a signal each to two ts jacks.  Makes it easy to swap out different length cables too.

You could wire in a stomp switch to mute one side, or maybe a kill switch.

I agree. This is a solid solution and could easily be done with a 1590A enclosure.

Not that i know of but you could use Techflex  to hide it.

Honestly this is a great idea. My only concern is that I need to make 2 Y cables per pedal. One for LR in and one for LR out. That'd be 6 splitter boxes, no?

That looks really good and so professional. I'll definitely do some research about that combination. Thanks dave.

best tronics sells the george L cable. I have used mogami mini cable from Redco and it is pretty small, too.

Thanks for all the replies, you guys gave me some really good things to try. I appreciate it.

Sorry for delay. You could build one big box with all the splitters but really doing it at the cable seems iffy unless you can buy something that's over molded.

Hope I'm not misunderstanding but I think you can do a bunch of trs jacks into two ts jacks.

If you're looking for compact, look at Hammond's 1550A.  It's only 3.5"x1.4"x1.2".  Perfect for simple projects like this.  Jameco sells them, but I'm sure there are others.

I think you may be misunderstanding me, although maybe i'm misunderstanding you. If I'm understanding you correctly you're saying to make a box with multiple TRS jacks but only 2 mono jacks, but I need to go
L/R in -> send of the switcher
L/R out -> return of the switcher

But for 3 different pedals. The H9, Bigsky, and Timeline all need to run stereo to the switcher. That's where i'm not sure if i'm following this box because it only have one set of mono jacks. I'd love to understand what you mean, thanks again.

do you just have a single input and output for the switcher?

or is there separate ins and outs for each pedal?

And I do think I had it reversed a bit- the trs jacks are at the switcher, not at the pedals, correct?  I get the l/r to send and l/r out idea, but not what you want to do for each pedal- depends on what you can do at the switcher.

basically, my thinking is that you can do anything in the box (or boxes) that you would otherwise do with the cables but its more reliable.  You would just wire it differently based on the available inputs of the switcher.  I can draw a quick and dirty schematic that should help if you like, but I'm away for a few days.
