Thanks Alex,
I got it from Hobby King. It's the TBS (Thomas Benedini Sound) system. Essentially 4 parts required.

1.Sound Card.
2. Amp
3.Speakers (2)
4.USB dongle. (Usually only need to use it once)

www.benedini.de (The manufacturer's website) has the manuals, and the sound files to download to your computer & USB "dongleate" across to the card.

I'm hoping to be at the field this Sat Morn to giver her a fly.

Cheers
Andrew
