thanks, John,
Sometimes, at conferences, I have the feeling that most people use Sennheiser, so its easier to pick up a similar frequency of, e.g. the speaker on stage.
Or am I talking nonsense and could I do the same with an Audio Liminited set.
I also ran into a Lectrosonic 100 rec. transm. set, not so sure about that! I heard it's not very popular, unlike their other stuf.
