RCA Line Audio Output Converter: Speaker to Line Level Converter Convert Speaker Level Outputs to Line Level Signals Allow Speaker Line to Connect to Auxiliary Inputs of Portable Sound Systems

It was exactly what I needed in order to hook up a USB turntable to my computer for encoding. I didn't really need two but the price was still good even though I only needed one.

Good quality, surprised to receive two sets with two channels each. I mistakenly ordered twice what I needed.The inputs are adequately isolated from each other and the outputs by >2Mohms. The grounds of the line level outputs are tied which seemed to work fine on my old 4 channel amplifier.

I bought thse for DIY amp preamp experiment really did not work for my purpose but are keeping them around until I can try them In a more conventional way

The hookup wire used is very small and delicate 24 gauge stranded, so you might need to solder it inside some very small brass tubing bits to get it to fit securely inside your banana jacks if that's how you are going to hook it to your system. Other than that - great value for the money. There is a much better quality one made by BOSS audio you can find on Reverb for about 20 bucks and it has full sized wire and is in a metal case, adjustable levels too, but I haven't received mine yet so I can't make a sound comparison. Anyway this one works once it's hooked up. I'm powering my Yamaha P2250 off the two main channels of my RX=V365.

Clever way to take a cheap little speaker output and put it into a stereo amp.

Wires are to thin for any gauge wire. I do not recommend it

You don't know you need this until the day you need this (for me an older HTIB to Echo Dot). Easy to set up wiring and does what it is supposed to do.

Tried to use to drive sub amplifier from line out of amplifier. did not work for me Could have been myfailure?
