Bruit de fond lors de l'enregistrement

Mais je ne peut pas avoir de son sans passer par le pc

En fait le bouton mixer quand je le tourne à gauche j’entends que le micro

et si je le tourne a droite j’entends rien (on les pistes sur avec lesquelles j’enregistre)

Tu peux aussi vérifier une fois que tu auras réglé le problème de volume, si en bougeant les câbles tu as une différence au niveau du bruit de fond (dans mon cas, c'est souvent au niveau du câble USB).

Le volume "phones" quant à lui devrait être autours de 5 (milieu). Tu as quoi de ton côté?

(...) I can confirm the reports that the preamps don't have enough gain to handle dynamic mics-- I tested a Shure SM 57, a Beta 58 and and old Audiotechnica dynamic. You have to turn the gain all the way up on the Audiobox and get right up on the mic to get a useable signal. That leads to a problem with Channel 1 -- when the input volume is cranked up all the way, it begins to emit a high-pitched whine which will go into the recording. You can get rid of most of it by unplugging the laptop, so it's a grounding problem with the laptop--other devices have caused that noise also. But it's a nuisance, since the pathetic battery in my HP won't last for more than an hour. Oddly, Channel 2 on the Audiobox doesn't have this noise problem.

My workaround for this is that I have an Art Dual MP preamp that will add more than enough gain so I don't have to crank the Audiobox's inputs up that high. That also diminishes mobility, but it is a good backup. If I want to use just the Box without the preamp, I use Channel 1 for my guitar input--I play both acoustic and electric through mostly a Boss GT-8 processor, and the output from that sounds beautiful recorded through the Audiobox. I plug my vocal mic into the quieter Channel 2 and can put down a good-enough quick and easy recording that way.

I've also recorded a stereo acoustic guitar track with a pair of Oktava MC-012 condenser mics. They provided plenty of gain for a good signal without having to crank the input on the Audiobox up to the noisy range, producing a very good recording. I can also plug my Martin acoustic with an active piezeo pickup directly into the Audiobox and get a good signal. I've also recorded the output of my Roland electronic drums directly into the Audiobox with good results. (...)
