Yeah, currently we route the sound through a channel on the sound desk, and use PFL to preview. However, this can be an issue, as the sound guy is usually busy before the service with all sorts of demands, and with the exception of myself, none of the projection guys are sound trained.
It was just a hopeful suggestion to ease the job of both the projection and sound techs, I realise that its not high on the list of requests!
