RCA jumpers

[Fred Sanford]

Hey folks- I'm looking for a supplier of RCA jumpers, the solid-wire kind usually found jumping pre-out to power-in on a receiver, or EQ loop, etc. I've seen suggestions to use stainless steel bicycle spoke material, but are there any places to order these in bulk these days? I'm setting up a Tascam mixer and patch bay that's all RCAs, and these would be useful for quick bypassing.

I've looked at Hosa, Parts Express, Sweetwater, Radio Shack...any other ideas?

Thanks in advance,

I've seen Audioquest make these short Cable Jumpers, sold at places such as MusicDirect and even others make them, such as Cardas, and Cobalt Cable I believe too, but do you want to spend $25, and up for a pair of Jumpers?

If you were wishing to perhaps replace the U-Shaped Pins on a good reciever, then yes, I would say the $25 cost will net some sonic improvements. If you're wishing more than one pair, then this can get mighty expensive.

I dont know about Bike Spokes, but I think I've read of people using Welding Rod? Somebody correct me if I'm wrong, but isn't the required diameter 1/8"?

PS: Yes, for U-Shaped Pins, something like this "might" be fine, for longer runs in a patch bay, etc you might run the risk of shorting out equipment if they are not wrapped-shielded. Mark

These are specifically for the purpose of bypassing a neighboring pair of jacks that form an in-out loop either on the body of the mixer (for testing or remote use) or at the patch bay. I'd need something like 20 of them on the Tascam board I'm looking at, just to fire it up and test all channels & subgroups. Did it once with Y-jacks, but want a neater/cheaper approach. Home-made is too risky and tedious, don't want to wreck a good jack with a raw edge on a home-made jumper.

I figure the knowledge might be helpful to those that find receivers missing them from the EQ loops anyway.

Thanks,

The 14mm jumpers in my link seems to fit my Nak receiver, but my Tascam patch bay looks to be 20mm. I'll check the board(s) and Denon integrated amp next for reference.

Distance between center pins of RCA connectors:

14mm - Nak RE-1 receiver

16mm- Tascam 244 4-track and Tascam M50 mixer

18mm- Denon PMA-920 integrated amp

20mm- Tascam patch bay

Excellent. :scratch2:
