I want to play a CD that is made up basically of silence mixed with
an announcement that comes up every ten minutes - though the same
speakers at the same time as the music.

Can I just get a small walkman and connect it to the speakers in
parallel ?

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.

Yes. I wonder if there is such a thing as a post-amplifier mixer...

You could use the outputs of the power amplifiers into a passive mixer
with suitable attenuators and then feed into an external amp. I suppose it
is possible to make a mixer running at LS level using transformers, but
I'd guess an expensive option.

Or you could tell the boss: "Sorry, it's not technically possible at a
reasonable cost" and spare your co-workers the horrible inevitability
of the announcement :-)

You could even turn of the Muzak off completely. Though that's
probably against the law now ;-(
