I have indoor/outdoor wireless speakers and I'd like my audio receiver's music to play through them. The broadcast unit for my wireless speakers has a 3.5mm input. I converted the earphone output to 3.5mm with an adapter and that works well. However, when I do this, the music doesn't play through the audio receiver's speakers inside the house. My question is: Can I attach red aand white RCA connectors to one of my sets of speakers behind the receiver and convert the RCA to a 3.5mm to fee the broadcast unit?

Yamaha RX-V473. I don't have a problem with the effect of the headphone output plug. What I would prefer is to send the sound to the broadcast unit without having to go through the headphone. I bought a video relay/transfer box at the local electronic store and connected with the output in the back of my Yamaha and found that works for the radio stations. My problem appears to be solved.

Hi
Not a good idea to feed a speaker level signal into your wireless transmitter,its designed for line level which the headphone output is close to.
Does your receiver have any outputs apart from headphone and speaker.

You should connect the transmitter to the tape record outputs of your audio receiver. These will not be affected by the volume control of the receiver so you can adjust inside and out individually. You just need a 3.5mm to stereo RCA adapter to do this. If you use speaker level you would need to use a speaker to line level adapter and the volume setting would not be separate.

All good suggestions, but what you are proposing is not all that bad. If you wireless base unit has a level control, yu can probably connect the speaker leads. The only danger is getting the wiring wrong and shorting out the amplifier -- a costly error.

If you have a recording output, that would work best. If not, you can make up an 'adapter' like this:


L speaker + --------[100K resistor]-------center of white RCA
L speaker - ------- [100k resistor]-------outside of white RCA

R speaker + --------[100K resistor]-------center of red RCA
R speaker - --------[100k resistor]-------outside of red RCA

This will isolate the signal and provide enough attenuation that the signal should not overdrive the transmitter.
Make sure you watch the polarity, or you will not get any sound for one or both channels, or lose all of the low frequencies.
