terrible audio feedback

[kyrotech 0]

Hi guys,

 

here's my problem

I'm using a GV-1240-8 with all 8 audio

I am using top quality amplifiers and mics - Shure mics and Rolls amps

no matter the setting, there is always a feedback or a wom wom wom sound

I have tried setting up a system at our labs, and no matter the mic we use, it always has that wom wom wom sound coming back.

 

Now, my question is, is there anyone out there that uses the GV audio on a regular basis and not have this problem? Or is this an issue that is not important?

 

thanks for your help

Feedback as in the system is hearing the audio being played?

 

Have you tried listening to the audio through earphones?

 

Or not having a mic anywhere near the machine that is playing the audio?

feedback is coming from somewhere, no matter how low I put everything, there is always a wom wom wom sound.

when listening with earphones, its worse because we can hear it even more

there is no mic near the system

 

the setup up is for a hospital. they have the system in one room and the mic, speakers and camera in another.

 

anybody? this is driving me mad....

try going into your pc sound prop. and remove the tick on echo and reverb

I would try to disconnecting the preamps from the computer and listening to them directly. This will tell you if its a problem with the PC and/or Geovision or if its a problem before them.

 

Also be careful running audio wires near power wires. You can pick up some noise that way.

Another tip is to keep the mics as far away from air ducts and vents as possible. Most will pick up wind noise.
