Cut Out The Noise

[Digital Party]

I am posting here because I have no software problems, it's my AMP.

To run a better show I need to quite down all the buzzing from my speakers. Anyone know of some websites that show devices that isolates these ground loops (the cause of the noise). I guess it would go between the mixer and the amp, right?

Thanks,

A ground loop isolator may help in some instances but it is better to find the source of the ground loop if possible.
In my case I had a system hook-up that was noiseless untill I re-installed everything in a new cart. I had a terible hum. I carefully checked every connection, all were ok.
Then I discovered one of the screws used to hold the pre-amp to the cart was touching the case that operate the lights. That was the loop that created the AC hum. So placement of the components, checking all line cords for a good ground connection are important to reduce or eliminate AC hum.
To me the best cure is to eliminate the source. Anything else is a work around.

Wow...that's a lot of work

I just solved a Dell Laptop's Hum w/ a 3 prong to 2 prong 'Ground-Lift' adapter.

I use an 1/8 Stereo to XLR (M) w/ Shielded Cable to solve my HP Laptop's Hum.
This Shielded Cable has solved 3 x 'Desktop/Tower' PC's Hum problems.

Just encountered an Equilizer that picked up a radio station (90.1Mhz) -- The EQ had both XLR and 1/4" Inputs -- I was using the XLR -- but ended up adding the 1/4" to it (nothing attached to the other end) and the Radio Station was gone! (I even attempted the Ground Lift) -- Their Engineer (Peavey) suggested that as a solution.

And of course the old standard -- 'Dirty-Power' problem - reducing the 8K of the EQ will help -- but the Freqency's that you lose are detrimental to your sound quality.

Agree w/ jdavia -- Isolating your problem hum is 1st priority - and the hardest as well!

How would Y'all handel "hiss"?

I got some, but not much,
It's just enough for the folks with "Good ears" to mention.

Not sure of the source of the hiss. But if it is in the file itself, you can turn the Treble or other control to suppress it some. It will also affect the song's high tones.
On the other hand the hiss could be from the way the amp was designed. I can't think of any other way hiss can be caused, except by a weak signal or poor recording.

Don't know if the ground loopback and hiss problems have been resolved but here's some advice just in case..
Ground loop: Run all your equipment into the same power source. I use a power conditioner. IF the supply is wired properly and to a good ground, you shouldn't have a loop problem. In the case of an open ground, I have had to ground lift my Dell laptop as well. Not the best choice.

As for hiss, it is usually a sign of too much gain on a noisey effects processor. turn off the effects and see if the problem goes away. If it does, then adjust accordingly for a happy medium.
