Hi there

I've come by one of the old dbx 160x units. However, it gives an unacceptable buzz when I crank the output gain above 0. It loses the buzz when I bypass the unit or turn it back down. Could this be a grounding issue?

Other important stuff is:

Hey guys,

I uploaded a vid of the mixer and the noise, check it out

I just got a multi-track recorder and I'm new to the process so excuse my ignorance. After connecting the LINE output from my amplifier to the recorder and turn up the volume on the recorder, I can hear a consistent hum noise, but when I touch the recorder itself with my hand or one of the 1/4 cord inputs connected to my guitar or the recorder the noise almost completely stops..

I got an Altec 1567A mixer and hooked up a line level signal (like a CD player) to input 1 octal socket pin 7 hot and 8 ground. Pins 5 & 7 are linked. The output is connected to output octal socket pin 7 hot, pin 8 ground. It has a bad hum/low frequency buzz, I think its the way its hooked up. I don't think its the unit itself and I tried lifting grounds on everything except the mixer.

We are getting a small hum/noise on our wireless mics intermediatly. We have Flourescent lights in the Sanctuary and stage area at this moment. Is there any thing we can do to stop this/cut it down for the time being until we get stage lights?

I am currently running a cad condenser mic into the PreSonus bluetube preamp, into my compressor, then into my mbox. I am hearing some weird high pitched hum that won't go away? any thought to what this could be from? i check the connections and the cables are fairly new. Any help would be awesome thanks again!

Hi. I am getting a lot of extra noise and hum when I record into my computer. This is my setup:

I have a Samson C01U USB microphone on my new Vista OS. The microphone works, but no matter what settings I try, there is always a very audible 'hum' in the recording. I've tried recording with both the default sound recorder and Adobe Audition 3.

Greetings. I will be attempting to record a drum set for the first time ever, Monday, and was wondering if anyone would be willing to offer up any advice on getting a decent sound with what I have available. I know the kit is made by Tama and sounds pretty good live. He also has an assortment of Zildjian cymbals. I'm looking for a starting point as far as mic placement goes.

My recording engineer wants me to up-grade my single coil pickups on my Fender Jazz Bass to eliminate the hum.
In reserching the problem, I've found that these two stock single coil pickups should cancel the hum themselves by design.
How do I check the polarity of these pickups to see if they are installed correctly?
Are there any other tips for eliminating the hum?
