When in Rome... What voltages do they come in ? Graham

You don't seem to be able to get your head round that. I bet it doesn't *REQUIRE* 3 phase at all. Graham

Camlocs and tails is how its done. from county fairs to festivals to one off at the college multi use room if you want to recreate the world eyesore be at it but your tilting at windmills, as is par for the course with you George

You haven't read the thread. you haven't even a clue what the discussion is about. We are talking touring desks, and just like Graham you spount nonsense that doesn't apply. Anybody who has done a few gigs knows everythinbg you posted about 240. I never said 240 wasn't available. I said I ain't gonna run 300 feet of 240 to mix position because some silly little company wants to build their mixer that way. Grow a clue or brain, whichever comes first.

Please list all the venues in the US with 240 at MIX posuion. Then all the outside events. Your entire argument gets sillier with every post. You are just plain wrong, and gwatts is a bonehead who doesn't even understand the discussion. Siding with a bonehead just because he agrees with you isn't good policy. |
