I have a PowerMac G5 that I use at the church to run videos, slides, etc. Problem is that the sound from the computer to the mixer has a constant and annoying buzz. I have it hooked up with the 1/8" stereo jack out of the back of the computer and then dividing to a red and white rca plug into the mixer board. No other channel on the board has a problem except the one from the computer. When I record the morning services the buzz is present on the recording as well. Is there another - better - way to make this hookup or is there a solution?
Thanks
I have been running a GoToMeeting app through a USB Codec Cable to a Peavy mixer. There is a slight buzz until GoToMeeting is initiated - and then a high-pitched hum that is a complete distraction to the speaker. After exhausting several different cables and connections, I finally figured out how to eliminate it.
The problem is bringing vocals across an analog mixer and sending them into an iMac digital port. Meanwhile, GTM is also sending a digital feedback into the analog mixer, then to the amp and speakers. In spite of the digital port on the mixer, it doesn't do what it needs to. Thus, I finally laid hands on a Focusrite Scarlett Solo (3rd Gen) USB Audio Interface unit that ran $119. It converts the analog to digital coming to the iMac. ALL background noise is gone. Note - after installation, reboot the machine, or you will think it is not working for you. Make sure you select the Interface on your input settings, both on the iMac and in the GTM settings. You can continue to use the USB Codec cord for audio out.
