Noisy Audio In G5, noisy audio in G5 Options

[crazyoval]

Hi guys.

I've just got myself a 2nd hand dual 2.7Mhz G5 running 10.4 and 4Mb RAM. Ive upgraded from a G4.

I have an issue with the G5 in that there is a lot of background noise, when I turn the volume up its like a bleeping sound mixed with buzz and crackle as I move the mouse around the screen. I had this on a G4 Powerbook and I could only stop it when I disconnected the power, clearly an option I don't have on the G5.

Has anyone else experienced this and has got to a solution? Ive done a search for 'noise' but couldn't find anything else.

Thanks in advance....

Yo, crazyoval... You can put your computer in another room... Only hassle CD's/DVD's... The best solution is below... But, it is expensive... Probably take the money you saved on your G5...



Noren Acoustilock gCab Computer Cabinet

Paul White

Computer noise is a major problem in the computer-based studio, especially where instruments or vocals have to be recorded in the same room. This product is designed to tackle such noise, and is essentially a soundproof cabinet with in-built cooling system. It's designed to accommodate anything up to the height of a Mac G5. There's a little width to spare, but it's not much room for any external drives, unless you can stand them on edge next to the computer. A modern Firewire drive might also fit on top of a G5 at a pinch.

Noren's cooling technology uses rods with exceptional thermal conductivity. One end of the rod projects into the box with the heat source while the other is fan cooled in a separate chamber, which means that up to 800W of heat can be extracted without needing a direct air path.

Separate fans circulate air over both ends of the rods, and extract the warm air via an acoustically absorbent ducting system. Because of the width of the heat exchanger system and the thick foam cabinet linings, the cabinet ends up being a fairly bulky 26 x 24 x 32 inches, even though the computer section measures only 22.75 x 12 x 24 inches.

The cabinet is black (although Maple finish is also available at no extra cost) and built from laminated MDF. Doors to the front and rear, held closed by basic catches, are kept airtight with foam gaskets. The rear door's gasket is thick enough to allow cables to exit the box simply by being 'trapped' in the door. A sliding base allows the computer to be slid out if necessary.

Even without the castors supplied, the gCab was too tall to fit under my studio worksurface. However, having set it up to one side, its top provided useful extra workspace.

The specifications state that the noise level of a desktop G4 computer can be reduced from 61.5dBA to 37dBA in the gCab. Tested subjectively, I found the gCab to be virtually inaudible, even when listened to in a quiet room, which after all is what you need to know. Given the complexity of building and shipping a unit like this, the UK price seems pretty fair, though it still seems a lot to pay for keeping your computer quiet, as you could buy a halfway decent PC for the same price. Nevertheless, if you need a quiet environment and you have space to accommodate the gCab, it could make the difference between being able to record in the same room and not.

Mac Daddy. Although your second option is a great one, the price is a bit high for the general user. Your original option of "stick it another room" or at least at the other end of the room, I think, suites well.
Considering VGI or VGA cables are around £50 each, with a small expense of all the other long cables you might need, such as MIDI USB FIREWIRE ETC... you probably won't have to shell out the expense of having a cabinet.

Lepetitmartien. The SMU motherboard. Has that got anything to do with cable or mixer noise reduction?

Your choice crazyoval.

Mac Daddy, what a great sense of humour you have!
I only found out what they were called by joining another forum that only talks about such things
Best.
