Reply with quote  Mark this post and the followings unread

Can someone with their expertise please let me know what they think might be the problem why I am getting lousy noise in my recordings from the BR8 to the computer? I've tried going out to my stereo as a preamp or just straight to the Digital Performer on my computer and it is consistently noisy.
The BR8 is clean when listening to it alone. It's as if I am picking up the signal of the fan in the computer onto the track I record into DP.

Any help is greatly appreciated. Smile

welcome,

assuming you are on windows and using the built in sound card it might be the case that in the sound mixer the microphone channel is not muted.

When the computer has a built in microphone you might actually be hearing the fan indeed Very Happy

Erm right click on the volume icon to reach the mixer, or find it in the control panel.

you are using a G4 tower

would it happen to be the Mirror Drive Model

the dual 850, 1.25 or 1.44 Ghz ?

if so...that is your problem i am afraid

those models have a well-documented problem with an internal noise issue with PCI audio cards

Thanks for the reply. My G4 computer is only a 400mhz power pc G4 tower.
I think Blue Hell might be on to something about the fan. I'll try cutting the internal computer mic sound down cuz I haven't been doing that.

Glad I dropped in to this site of so much acquired knowledge floating around.
