Hugh Jampton (I guess you are a Goons fan?) - you enjoy your anonimity and so do I. Suffice to say that my club is not in Kent or anywhere else in the UK. I described my system and procedures accurately.
To clarify my post, unlike analog frequency analysers, the "pink noise" test is done only once for each room in which you use the gear. The Peavey digital EQ (it's in a flight case in my garage but if anyone wants the model # I can get it) will store and remember multiple EQ settings. In addition to the Mains EQ tests, I also use it to set up the stage monitor EQs. It is the same procedure except the mic for the Peavey is on stage facing the monitors (a channel on the snake can temporarily be used to bring the sound back to your console position). The Peavey also works as a real-time frequency analyser - a very useful tool. I do not use this unit as an EQ as it is too difficult to adjust quickly - I transfer the readings to analog 31-band EQ units with sliders at each frequency for easier control. (The Peavey unit has an backlit LCD readout and you have to scroll along the 31-band frequency range to the one you want to adjust then up/down the arrow keys to adjust it).                                          
I posted in defense of us poor sound guys what gets the blame if the band sucks! We even have to drag all this gear in and out of the place.
I also posted to help any aspiring sound persons (yes, you women can do this too if you can lift a 60lb speaker (or can persuade somebody else to lift it :-)) out there with what I have learned over many years of running the board.
