brilliant! i tried what you said and it worked a treat! thankyou very much.

thank you for the quick response. i'll give it a try.

i have a betapack 2 which seems to be not working properly. i can rule out control system problems and the problem occurs using both analogue and dmx inputs. channel 5 + 6 seem to not respond properly to control inputs, the fader does nothing from 0% to 70% then above that just suddenly comes on to full brightness. can anybody tell me what is wrong with it please? i bet it's just a 20 pence component gone wrong or something. i need a quick fix, got a show starting soon.
