Inverting an RCA selector

Hi, I'm new in the forum, hello to everybody,

I have one source, that is my computer and an audio wireless receiver (nuforce) near my amplifier. I need to add also my headphones so that i can decide to hear the headphones or the stereo but i need a switch that makes me select the output having only 1 source coming from my receiver. I found some simple rca selectors on amazon but they have 2 or more rca aux and just 1 output. What if i invert it and use the input as output and the output as input for the source, so that i can use the switch to select the output?

Thank you very much,
HJ

 

An electrical connection is an electrical connection. I can not think of any reason why it can't be used in reverse unless it was more expensive and had some sort of diodes or other electronic components to force one way electrical pathing. But in a cheap selector this would not be the case.

I am not sure where you want to switch from headphone to amplifier as the computer should automatically give headphone priority if you plug them in, and so would most recievers so I am guessing you have maybe a headphone amp that you want to run from the wireless receiver? You can always try a line out from the receiver to that next device, better yet if it has audio pass through so that it needs not be on.

 

Hi, thank you for the reply. I'm trying to have the less cables coming out from the notebook, that's the reason why I'm trying to use the wireless receiver near my stereo. The system is, notebook -> nuforce wireless transmitter -> receiver -> amplifier / (headphones). Some people in the reviews of the product use it inverted to connect two amplifiers and say there's no problem. I wanted just to be sure not to damage anything. The product is the following HQ Commutatore stereo a 3 uscite: Amazon.it: Elettronica. Another solution is to use the tape out from my amplifier, maybe it just passes through.

 

Not when it comes to RCA selectors, Master Viking.

They DO have diodes in there to make sure the signals don't cross (the connections being analog and all).

A multiple input multiple output RCA switchgear doesn't exist (at least not anymore).

But there used to be switchable ones which have multiple inputs to one output.

Don't know if they exist anymore. RCA connections is going the way of the dinosaurs.

 

So maybe the one who wrote in a review of the switch saying that its using it inverted to switch from one source to two amplifiers and that is working well would have a loss of signal and didn't notice it?

 

A mechanical switchgear maybe doesn't have diodes to keep the signal flowing in the intended direction. But I've opened up the old splitter I have and it does have diodes to make sure the signal only travels in one direction.

 

Nothing $10 and some fun from Radio Shack cant fix, just make your own on a bread board and any kind of switch you want with RCA headers

Heck back in the day I used a DB25 connection to make my arcade setup modular.

 

Thank you all for the precious information... i will try to sort it out some way
