Emac Audio Problem
My brandnew Emac 700mhz has a good amount background noise in its audio output making it unusable for professional recording applications like Cubase. The high pitched sound changes loudness and frequency depending on the position of the mouse on the screen so it seems that maybe there's some stray voltage coming in from another sub system (graphics perhaps?) I went and bought a professional USB audio adapter from Edirol ($250) hoping that may fix the problem. It brought the noise level down at least by 3 times but the same ever changing noise is still there in the background. It seems to also transmit itself somehow through my MIDI devices as well and then show back up on the MIDI device's audio output. It looks like a design flaw to me. Maybe some components that should have been shielded better on the motherboard. I need help. This computer turns out to be unusable for any kind of music recording. My old iMac has none of these problems and is totally noise free even with just the built in 1/8" audio output. Any advice how to fix this? I don't want to have to buy another computer. Thanks, Alan Steward abaco@go2mypage.com |

the monitor is the biggest culprit of background noise... especially if recording guitars as the pickups are very sensitive... if recording guitars, keep pickups as far from monitor as possible and face away from monitor. Keep cables and device as far from monitor as possible also... this may help but not totally solve problem.
