Hi!

I bought the Presonus USB interface (Presonus Audiobox Studio Pack, including the mic and the headphones) three months ago and I have a very annoying noise (static noise or white noise) when I turn the phantom power on. I have tried so many different things:

- I changed the mic (Presonus M7) for another condenser mic
- I changed the audio (xlr) cable for another.
- I separate the power cables from the audio cables and the Audiobox Usb from my PC to avoid some possible interference.

Furthermore, I have to turn my studio monitors off (M-Audio BX5 D2) because I hear a lot of noise while I'm recording, even if the main volume is all at the left (no volume). What can I do? If I sing very near (three fingers from the mic) I can reduce the mic input gain and so the white noise, but I think this is not a solution, because if I want more volume, I must increase the input gain so the static increases too!

Thanks for your help!

Excuse me for the double post, that was a mistake.

Thanks for your reply. I try a lot of things to resolve it so I'm not very hopeful abut this... if anyone has a possible solution I'll be very grateful!

Thanks and bye.

And how were we supposed to know that? You said nothing about it in your previous posts.

Of course, that's why we're here. That being said we cannot help you without a bit more info......if you
will post your system specs (see my sig), we will be better able to trouble shoot your problems.
Without knowing what type of pc you're running, what OS you're using etc....we can't recommend a
specific course of action.

Ok, Cristofe, it was just a missunderstanding. Let's see:

- Audio interface: Presonus USB
- Microphone: Presonus condenser. The one that came with the Presonus Studio Pack)
- Headphones: Presonus (sorry...I don't know the model but it's the one that came with the Presonus Studio Pack)
- Studio Monitors: M-Audio BX5-D2
- Keyboard: Yamaha Piaggero NP V60
- Guitars: Spanish guitar, Hohner electric guitar (only connected when I need one to use them)

- Computer: AMD motherboard with AMD AM3+ four cores processor, 4 gb DDR3 1600, 1TB hard disk
- OS: Windows 7, 32 bits
- DAW: Studio One Artist

- Other factors: No fans in the room, cables are new, power cables are as far as I can from audio cables, USB Presonus is as as far as I can from the computer and mic is two meters from the computer (to avoid the computer's fan noise while I record)

If you need more info, please tell me.

Thanks again for all your help

This could possibly be a ground issue. Perhaps try a different outlet, better power conditioner etc.....if you have a laptop that you can run on battery power you can test to see if this is an issue.

I also thought about a ground issue but I live in a new flat with a new electrical installation so it shouldn't be that issue... I try on my laptop but it only has 1GB ram and the processor is too slow to run with audiobox so it can't run the DAW.

Refered to the power conditioner, I use an extension cord (something like this: http://www.freewtc.com/buy-extension-cord-37950/) so I'll try to connect the computer (that provides power to the USB Presonus) in a different plug...

I don't remember if I said that the monitores make static noise but the headphones output make a louder noise when I turn the phantom power on. I haven´t another headphones so I don´t know if it's a headphones problem, a headphones output problem...

Thanks again!

I have the exact same issue with the audiobox too. Tried with different USB cable (even one that has two ferrites), tried in my notebook using batteries and nothing changes. Tech support closed my ticket without solving it, so I'm pretty disappointed. It seems like a very common issue with the Audiobox USB (or the M7 microphone).

I will be monitoring this thread for solutions.

Hi, nathanowna

It's not a mic problem because I try another condenser mic. Without the phantom power the noise is normal (I can hear it but I think that a bit of static noise is nornal, isn't it?) through the monitors and annoying through the headphones but when I turn the phantom power on the noise is very annoying through the monitors and through the headphones so I can't hear nothing clearly and, of course, I can't mix. I'm very dissapointed with this issue too and I can't find any solution!

Let's wait for an answer from the tec support or from someone who has the same problem.

Cheers!

The irony: the HD7 headphone is so good that it captures this noise. It's barely hearable on a speaker, but very annoying on the headphones. I attached a sample of it.

Hello, I'm Gerardo, I'm from M'exico and I have the same problem with the AUDIOBOX USB. I though of the ground and tried it on a laptop and it was noisy too. I've changed the usb cable and it is better. Ive tried with a USB HUB with a AC/DC and it was worst. What can we do to solve this problem?!
