Mbox 2 hum and computer data sounds ?
Hi there, I have been working with my Mbox 2 with headphones for the last few months.
I now plug in 2 TRS balanced jacks into the mon outs and connect to a XLR balanced input Amplifier. The Mbox hums a lot, I can hear computer data (like a fax machine) whistling in time with the booting of PT LE 7.3 and it is constant once the programme has booted and a session is open. This is obviously not right as it is awful and makes a mockery of the Mbox 2 audio specs. When I move faders and process controls the hum dissapears and then reappears when released. Why is it doing this and how can I resolves it? I can buy a soundcard for £50.00 and it does not hum with unbalanced outputs, why does M box 2 hum? I am running Windows XP pro, PTLE7.3 and no other USB devices attached to the system. Thanks |

Interesting (one word for it), seems many other people have exactly the same problem.
http://www.gearslutz.com/board/music...-familiar.html I would like the official line from a digidesign representative please. £300.00 for a unusuably loud humming sound. I am very dissapointed. |
Re: Mbox 2 hum and computer data sounds ?

Unbalanced leads make no difference at all.
I tried to connect a mini jack to 2 TS jacks to the headphone socket where there is normally no hum and connect this to my power amp and low and behold it hums and as noisy as hell. It seems to be when you connect Mbox 2 to another device that the problem appears. In addition the noise dissapears when the computer is processing ie moving an EQ parameter. All my mains is on RF / surge protected strips, never heard anything like this through any other audio device. And I have a TAGAN PSU which a high end server device. (cost nearly £100.00) This seriously sucks. How do you about getting a new Mbox from Digideisgn I am U.K. based. Thanks, sorry for ranting a bit but I am sure you can understand my frustration that the Mbox 2 cannot meet the audio specs of a consumer cassette deck never mind use for prosumer audio purposes. It's am embarrassment I could never have such a device in front of clients. |

In very few cases has this actually turned out to be a defective Mbox. The 'computer noise' is almost always a surefire sign that the problem is with the computer. Unfortunately we cannot control how well computers are built or designed and, unfortunately, some of them suffer from excessive noise being put down their firewire or USB busses. |

Learn to love it. That's my advice boss. There's something wonky with the buffering (or something like that) in the USB portion of the Mbox. My Mbox 2 at home does it and there are three Pro Tools rigs I have to use at work which all do it to a greater or lesser extent.
