Hi
I know this has been discussed many times before here. I just built a new compter and i still get pretty much humming and whining in my monitors when i turn the volym all the way up. The noice is probably only on the analog in/out on the Pulsar, because no humming is applied to the audio when recording through the digital ADATs.
I also discovered that the whining gets more prominant when using more of the CPU. Also when i move around the curser or a window there is a crackling noice.
Whenever the computer is busy loading a program, a window . . . i can hear it in my monitors.
I tried connecting the monitors directly to the pulsar outs, so the problem isn´t any other equipment.
I´d really appreciate your help

P4 2,53Ghz
P4PE-mobo
Matrox G550 (tried disabling AGP bus mastering, using the latest driver)
Crucial DDR2700 (1GB)
Pulsar2 (tried diffrent slots, now in slot1)
Lian Li-case (temps mobo 34C, CPU 41C idle)
XP-pro
Back ground noice, again!
Bastian, tnx for bringing this up again and mentioning the adat ins.
Jeeez, I'm monitoring digital - which I completely forgot
and the input comes via adat from a digital mixer, also noisefree.
When I include the analog IOs (Pulsar I), I get exactly the same result you describe.
My old Pentium with an ISA based Turtlebeach Multisound is also noisy at screen updates.
Not very smart if you apply some midi controllers and onscreen dials follow with a smooth screeeetch.
A quick monitoring solution would be to avoid the analog outs, if the noise is at a disturbing level, and use the digital ones instead.
A DAT recorder with broken mechnics might do the trick at very small additional costs, a working one could be handy for a quick record of the master outs.
cheers, Tom

Bastian, in case you haven't found out in the meantime:
It's the powersuply.
I exchanged mine temporarily and analog background noises were reduced >10db.
This wasn't even a quality PS so I guess a real good 450 Watt piece will be even better.
The window moving and mouse/menu actions seem to cause heavy loads on the PS and the analog in/outs of the Pulsar pick this up.
cheers, Tom

Thanks for replying
Tried the powersupply thing, switched mine to a 350W Enermax last year and it didn´t reduce the noice i think. Maybe a 450W PSU would do it.
I mailed to Creamware and they suggested to have a look at the card, also the distributers in Sweden say that they´ve experienced people with noicy cards and are exchanging them to new ones. But since i bought mine two years ago it´s a little to late to get it exchanged now.
Maybe i should just ignore the noice since i only hear it when playing really loud, i don´t hear it in normal mixing volumes.
One thing that reduced the graphics noice (moving the curser or window) was unticking "enable write combining" on the settings for my Matrox G550.

the problem with powersupplies is that they all look the same and many are certainly labeled wrong like those 200 watt multimedia speakers.
Best would be a try-before-you-buy, so a local dealer (as always) might be helpful.
A PSU is a serious piece of equipment, so it can't be a bargain, obviously.
The noise on my system was up 12 db by just moving windows on screen, but without HD activity, so I guess it will affect low volume recordings. It's not so much the level but the 'spiky' character of the noise which is annoying.
cheers, Tom
