Audio differential Signals

1 have a differential audio signal of 15Vpp and i need to attenuate it to 5Vpp. I need help

I believe what you're asking for is referred to as an H-Pad attenuator which is for a balanced signal. A schematic of the resistors required for implementation as well as a calculator for R values is available here for reference. Further details on passive attenuation including an explanation of the H-Pad can be found here, including decibel attenuation and its relationship to voltages. Hope this helps!

Unless you give us the details about the output and input impedance of the devices being considered it is not easy to advise you.

Agreed, and that's why I couldn't get any more specific than providing the links which I did.

If it's uses an XLR cable and you don need an exact ratio you could just use a 10dB pad.

I have used these in the past. And just an FYI, they are NOT exactly 10db, but less. Same holds for a 15db or 20db attenuators.
