Hello all you rockin' Pulsar guys
I have the following setup: Pulsar II w. z-link out, powersampler w. syncplate. 2 Luna i/o connected to powersampler and syncplate.
Problem: When both my Lunas are connected, and the cold wire of the audio outputs are connected between the to boxes, noise on the outputs starts. The noise somehow comes from the harddisk, because it sounds like the the crackling and hum, that physically comes from the HD in the cabinet.
A strange thing is that, if a program is started, then while the computer is occupied, the noise momentarilly stops.
My computer is grounded proberly and the cards are well locked with screwes.
Is anyone able to help me?
Chill

Luna noise
I'm still experiancing the same problem with my pulsar 1 + pulsar 2 srb. I know there are more people with simular promblems with noisy analog in/out on pulsar boards, but this is the first time i've heard coming from luna i/o boxes.
That would mean that the problem is not related to the i/o themselves being to close to the HD or any other source or interference.
This suggests that it must be or software related or it must be an other place on the boards that is picking up the noise.
I've tryed the support on this one but as offen i didn't get a reply....
Maybe we could bundel our forces and e-mail them all at the same time.
Cos monitoring sucks with noise recording is even worse.
Digital in/outs don't have the problem, i know but i need to record and monitor analog.
because i do not have digital monitors and i do not know of a digital microfoon and don't have it. so this is defenatly frustrating.
Btw. this is the only trouble i have with pulsar, love the rest of it.

Definitely NOT software related, but definitely electrical related, as with numerous machines and various I/O solutions, I have never run into the problem myself...
Usually this is caused by wiring INSIDE your computer, either nearby, or touching your CW card, or by the wiring your computer is plugged into (ie: your apartment's wiring). This can be very tricky to track down. First, open your machine, and make sure all extra power connectors from your power supply are ziptied so that they are nowhere near your card. Next, if you have another soundcard, like SBLive, or something, and this has a cable running from your CDROM drive, this can also be part of the problem (strange, but removing this cable between SBlive and CDROm has fixed the problem for someone before).
The final step is using balanced wiring and/or custom-made wires that lift the ground. It can also come from poorly shielded audio cables. Ground noise, hum, and harddrive noise is a problem with many different studios and different equipment... and it's always a little tricky to solve.
A few other ideas: sometimes this is caused by different paths to ground, so plugging into the same wallplug (if it can handle the load) may fix it, or plugging into different outlets may fix it.
Good luck and if anyone else has other ideas feel free to add them!

Someone at CW forum got it nailed down to a ground loop and fixed it via a ground-isolator inserted in the signal path right after the CW physical out's.
I have the same problem, and as soon as I've found me one of these gizmos, I'll give it a try.
Try "ground loop" at http://www.google.com for more info.
I can certainly not guarantee that it will fix anyone's problem, but it semms worth a shot to me

Thanks for the response
I have tried Creamware support quite a lot of times, but never got an answer. So yes lets hook up and join our forces to get some help from Creamware.
The irretating part comes, when knowing that Creamware obvisly has people who knows how these things works, but don't use them to help their costumers, only to develop new things for the company, arghh!
Let's tell them that to get happy costomers that will recommend their products and give them a good reputation, they must have a better technical assistance.
About the noise and the grounding stuff, I would understand that it could cause the noise, but teh strange thing is that it stops when the computer loads a program. Also it is only when both the boxes are connected together or through a mixer, that the noise comes. It must something inside the computer.
Peace

So what you're saying, is Creamware should take a guy off their development team to help solve ground loops in people's studios? 
But yeah, if you only get it when it's connected as you mention, definitely sounds like a ground loop... they can be tricky to solve and sometimes making your own specially wired cables between the offending devices fixes it, and this is sometimes the ONLY fix, too.
Check inside your computer, as mentioned above. Also, disconnect all wires you can, and start with one wire at a time, to see if you can help isolate it.
I wish you good luck in solving the issue!
