No.

Thanks Dave,

So I have to have some kind of simple mixer unit ? Would it be a
commonly used item that I could buy in a street electronics store ?

For such a simple job a passive mixer would do, but this relies on being
able to get at the inputs of the power amplifier of the CD system feeding
the speakers.
