XDR959 question - XDT4 cable
by SixStringMike on 2011-08-19 14:48:10

The XDR 959 system with the XDT4 transmitter and XDR2 receiver. The cable conencting the guitar to the transmitter is not working well, and I am handy enough with solder to make my own - I've purchased lengths of good quality instrument cable before to make my own with no problem. However, this little bugger presents the following challenge, and I'd rather ask a question than make a stupid mistake.

The original cable that connects the guitar to the transmitter has a stereo connector on the 1/8" end of it, and the owners manual says the following:

  • the tip is for a mic in

On the 1/8" transmitter end, there is a tip for mics, ring for instruments, and sleeve for ground.

On the 1/4" guitar end, there is only a tip for instrument and sleeve for ground.

If I would plug a mono connector into the transmitter, the part which would be getting the signal would be the sleeve and the ring, which is supposed to be receiving the instrument signal. So:

Question #1: I have a 1/8" mono connector that I would like to use to replace one end of a 1/4" patch cable I already own. Looking at the attached XDR2 output.jpg, I am inclined to think this will work. Perhaps the ring connector closes the loop when a mono plug is inserted?

Question #2: Assuming #1 wouldn't work for some reason, and I purchase a stereo 1/8" connector, should I put the ground from the 1/4" end to both the ring and sleeve connector, and only send the positive to the tip?

If someone has a wiring diagram of that cable, that would answer my second question, I'd just prefer to use the connector I already have.

Thanks!

In the above post - the images didn't show up and I was unclear because I didn't preview it befor ehitting submit - sorry about that. Please read the revised post below:

My plan is to wire the negative to the sleeve and positive to the tip - any reason this would not work?

This has been the info we've always provided users who are looking to create their own XDT4 patch cables:

  • Tip and Sleeve from the 1/8" jack go to the 1/4" Sleeve (ground), the Ring on the 1/8" TRS jack goes to the Tip (Hot) of the 1/4" jack.

Thanks for the speedy reply.

That answers question #2, but prior to that I'd like to know if I can use an 1/8" mono connector instead of the 1/8" stereo...thanks!

Perry - thanks for looking into this but it's good to go now. Check out the attached pics.

I had an inexpensive (but fairly good quality) 1/8" Stereo to RCA connector; something similar to what you would use for connecting an iPod to a home stereo.

I took off the RCA ends and wired the connectors per your suggestion and it works perfectly. The shielding is more than adequate and the 90 degree head relieves strain on the input jack.

For anyone's reference that is interested, the case was $6.97 from Home depot, and the belt loop is wicked strong plus you can run the guitar strap completely through a sewn loop and it CAN NOT come off. This is a very inexpensive solution to enuring your transmitter never hits the floor.IMG_20110820_011010.jpgIMG_20110820_010936.jpg
