Hi,
I run sound at a club and have had some weird things happening in the
P.A. I've had people talking and miscellaneous sounds fly in and out.
How is someone doing this? Is there a device they're using that can
pick up wireless signals etc..and break in??
Thanks,
George

YOu might want to provide a better description of your
problem if you really want some assistance.
SOmebody "picking up" wireless isn't going to cause you a
problem first off. I'd hope you have a little more
electronic savvy than that <g>.

Does it sound like a local broadcast station? WHat exactly
are you hearing?

are you using wireless transmitters for vocals or
instruments?

A little (in fact much more detail) than your post provided
would enable us to give you some guidance. WE don't have
enough information to do anything but speculate.




Richard webb,
Replace anything before the @ symbol with elspider for real

Back in the old days of the CD craze, i had a buddy who had a Trans-am
with a CB and a linear amplifier. He could pull up behind the building
of a Disco we went to, key up the mike, and have it come through the
system. RF overload can do some strange things.

I also had a old nuns home that i was doing a service call on the sound
system. The mother superior was out for some other function, and they
had a funeral in the building for another NUN. The old nuns asked the
mother superior when they got back if the dead sister liked Elvis and
country music, and how nice it was it was playing for the Dead nun.
The mother superior (who was not at the funeral) thought they all
lost what few marbles they had left. (they still all sleep with those
12" hard rulers from there school days, old HABITS are hard to break)
Turns out the sound system had a channel that had a mike preamp out.
This malfunctioning IC was demodulating radio stations and it WAS
playing in the sound system at a low level. Strange things sometimes happen.

Units with a lack of proper shielding, poor preamp design and layout,
non transformer inputs, and cheap parts can be more susceptible to
interference. It pays to also use good cables and stay balanced between
your gear if possible.

Thanks for the response Richard.
I'm using pretty standard equipment i.e. Amps, pre amps, line
conditioners, subs and towers...nothing out of the ordinary.
The bass player does in fact go wireless. I'm not sure of the
manufacturer or channel he's using.
To clarify my question, I was wondering if there was a device out
there that could hop on a P.A. or wireless guitar signal and interfere
with the sound?

Got any wireless mics?

What effect do the various faders and gain settings on your console have on
these sounds?

It could be as simple as an wireless device, even another wireless
microphone nearby, operating on the same frequency as one of yours.

It could be a two-way radio, walkie-talkie or even a baby monitor.

It could be a TV or radio broadcast station.

It could be intentional sabotage, but that is unlikely.
