if i connect the smoke machine to the same lead as the sound system i get a clicking noise when i press the button , coming through the speakers, so i connected it to another socket independently and it still did it, im guessing that the other socket was on the same ring main so thats why it kept doing it, any way of stopping it?

Possibly the best suggestion I can come up with is to connect everything up, and start clicking.

Unplug equipment one by one starting at the CD player end, and mess with the level controls until you get an idea of which bit of gear is being affected.

Does it, for example, still click with the master up, but all the channel levels down?

Its probably the relay contacts that activates the heating element. the switch on the remote probably wont be big enough to handle the current draw required when you activate the machine, on its own without a relay.

The contacts in the relay will probably be arcing (causing sparks) which cause interference to other equipment. This is possible on the lower end of the market machines. (Built to a price, not a specification)
Try putting the audio side through a mains filter socket, this may cure it.
