Have you ever wondered why you have a hissing sound coming through your speakers, after you have troubleshooted up to your you-know-whats?

Note that it could be a digital camera or some other similar device being used too close to your mixer.

And, if your response is, "No kidding, loser," then please note that you did not have to read beyond the first sentence, ya hoser.
 
Maybe it's you song selection that generates the hissing. Are you sure it's not the peeps?

Oh, ya...

I was playing THE SSSHHHHHHHOOOOP SONG.

:tongue3:
 
My Treo makes a static noise when I am near and it makes a weird noise a few seconds before somone calls.
 
You say you've troubleshot the hiss. What have you found?

Generally, the hiss is due to a noisy component. Unplug the mixer from the amp and see if you still get hiss. If you do, then it's your amp. If you don't, it's the mixer or a component plugged into it.

Try reducing the gain on your amp. Try setting up your system's gain structure per http://www.rane.com/note135.html.
 
Anyway...my story is this, which is why I wrote the post:

The other night, I wanted to take cool photos of the crowd (which didn't turn out, by the way) with my turntable in the foreground and the people in the background.

From the time that I pressed the camera's button, to the time the camera completed flashing and taking the pic, there was a period of hissing...it happened exactly four times, as I took exactly four pics.
 
The flash that is associated with camera is a culprit, apparently it is a high frequency something... same thing happens in a thunderstorm on am radio stations... You will get interference. Of course your equipment must qualify with FCC rules :p

Vinyl, Do Turntables still qualify with FCC Regulations (lol)?


Bounce, you are correct, any devive that emitts a high frequency (EMF signal) can cause Noise / Hiss through Cables.
 
Generally, Strobes sound like...

In my experience the strobe circuits usually sound like a whine. The frequency starts out low as the flash capacitor begins to charge then gets higher as the capacitor is toped off. Additionally the high piched whine will begin to cut out as the charge is applied intermittently at the end. The high piched sound continues intermittently as the charge on the strobe's cap is maintained.

The hiss is a new one on me. Out of curiosity, next time turn the strobe off and see if the sound disappears. If close enough even microprocessors of all types can induce noises under the right conditions. Cell phones? That is a lead pipe cinch, they're supposed to radiate. Stick one in a rack and I'd be surprised if it didn't induce a noise into something.

One bar I worked had the most annoying hissing sound that I could never track down. The dance floor light controls were behind the bar and the strobe was always on..That was probably the problem the whole time! Darn bar owners don't know nothing! :rolleyes:
 
I used to get a lot of hiss and hum in my old system. But none of the stuff was balanced, not even the cheap-arssed Ampex mic. :D

It was especially evident when the mic cable lay on a concrete floor.
