Subject:Re: Gig Power Issues

Steve,
With my rig I use a Monster Power Pro 3500 (also own a Pro 2500 for my PA systems' FOH drive rack) and love the units. The 2500 cost about $200 street price and it is very high quality power conditioner unit that does way to many things to ramble on about here. Go check it out here: http://www.monstercable.com/pro_audio/productPagePro.asp?pin=2141&LastPage=Monster%20Pro%20Power

Also, where are you playing tonight? Let me know soon, As I may be able to bring one out to you to use tonight.

Hi All,

I just got back from setting up for a park gig I'm doing this
evening and had some issues with the power that was supplied. It's
one of those gigs that's basically on a trailer stage and the power
is supplied by a generator.

I had a couple issues, mainly that had to do with how my Leslie
reacted to the power. The first was I was picking up some nasty
noise coming from the generator. The noise was coming out of the
Leslie horn and it seemed to go along with the frequency that the
generator was running. It wasn't realy a hum, more like a mid-to-
high frequency noise. Luckily, lifting the ground on my power strip
cleared up most of the noise, but I could still hear it faintly.

The other issue was that I was on the same circuit as the numerous
florescent lights on the trailer. As soon as a few of the lights
were turned on, the Leslie motors slowed down. Turning on more
lights almost made the motors stop completely.

I didn't have any problems with my keyboards or keyboard amp, just
with the Leslie. I was wondering if anyone knows what might have
been happening. Supposedly I was running from a 20 amp circuit,
which seems like it should have been plenty for my rig and a few
florescent lights. Do florescent lights and motors not play
together nicely? Also, what do you guys do in cases where the
supplied power is flakey, especially from a generator... do you use
conditioners, filters, etc.??? Is there anything I can buy that
would guarantee a constant voltage supply to my rig?

TIA,
Steve
