I assume that they are simple "shorting plugs" if used in a phono input.
They may lower noise a bit depending on the environment.
PS: DO NOT use a "shorting plug" in an output.

I need help
I have, since 1975, an integrated amplifier by Sansui model AU 7700.
It had what I think were jumpers connected to the right and left entry RCA connectors of Phono 2 that I suppose were, in the absence of the Phono 2, to simulate it.
I also suppose that the jumpers have an specific impedance.
I recently send it to maintenance and the technician lost these jumpers.
If anyone is familiar with this equipment, and what I am calling jumpers, could you please check if I am right about my idea of their function and, if so, which is their impedance so that I can manufacture a replacement?
Thank you very much for any information.
Fabio

@dekay is absolutely correct!. Never! use shorting pins on an output! Looked at image of your piece. Far left are 2 phonos. So those would be shorting pins. Far right are preamp out/power in needing RCA interconnect. Hope that helps. |
Thank you viridian, dekay, celtic66 and dill, very much for your help and I also want to apologize for taking too long to give you an answer. Aplril 21 is a national holiday down here in Brazil and I have gests that got me very busy. First of all it is really a shorting plug for the right and left inputs that I’m looking for. Here is a picture of the rear panel of my amp with the two shorting plugs connected to the Phono 2 input channels. https://www.dropbox.com/home/Public?quickview=id%3AHADsFIwKRTgAAAAAAAAFTw Well, if working the amp without them won’t damage the amp, I’m OK. I found many plugs on the net but none show the resistance. Can I use one with zero ohms or a resistance will be necessary? |
