    Help! Cloudlifter makes my Shure SM7B worse?

    Sign in to disable this ad
    I have a Focusrite 2i2 pre-amp, the SM7B and the Cloudlifter. If I use the Cloudlifter with the SM7B, the audio gain is incredibly low with the gain knob at 50%. If I raise the gain in adobe audition, it has so much white noise/hiss. However, if I don't use the Cloudlifter, and crank the gain knob at 100%, my audio is at a pretty good level with less white noise/hiss than using the Cloudlifter. I don't believe it's a cable problem, and I even used a second brand new Cloudlifter but to no avail. Am I missing something? Thank you for your time.

    GG!
    I did not read that you turned on the 2i2's phantom power, for the CL-1. It is easy to overlook that step. The CL-1 needs 48V phantom power. That is my first guess. Especially, since you tried two different units.

    Thank you for the quick reply! Yes, the phantom power is on. Forgive my negligence for not mentioning.

    No problem on not mentioning the phantom power... I only asked that because I have been guilty of not hitting the phantom power, for my CL-1, on more than one occasion.

    When you said that it is "incredibly low with the gain knob at 50%", what are you using as your reference? Is it low in your ears, low on a meter, low in Adobe? Are you seeing a green ring only, some occasional yellow ring, on the 2i2 gain knob?

    You said that you don't think it is a cable problem. Are you using XLR to XLR, for all of the connections?

    I am using the gain knob on the Focusrite pre-amp in terms of 50% as a reference. In Adobe with Cloudlifter at 0db the standard, the audio is incredible low and I can barely see the waveform. If I increase the gain on either the pre-amp knob or increase the gain in Adobe, it has all sorts of hiss. Again, at 0db Without Cloudlifter, cranking the pre-amp knob to 100%, I can see the waveforms and has little hiss.

    The cable route is as followed: Focusrite 2i2 XLR > Cloudlifter > XLR > SM7B.

    You don't happen to have a condenser mic to plug in to confirm the phantom power is passing through the cable going to the CL-1, do you?

    Or, if not, do you \have other cables to try, or at least swap around the pair you've got? Hard to believe you got 2 bad ones in a row.

    I'm with ya, Keith. Although I do not have a 2i2, but do have a CL-1 driving my RE-20 and SM7-B through my channel strip, I am beginning to wonder if the bus-powered 2i2 lacks the oomph to run that CL-1.

    Hmm...I didn't think that I might have two bad XLR cables. Currently I only have 3 so I may have to purchase another one. Unfortunately I do not have a condenser.

    Dale: (Apologies, I don't know how to quote two people in the same quote post) I know that the 2i2 can run the CL-1 as I've got it to work before. In a weird happenstance, I have two 2i2 and have tried them both. I thought perhaps it was a setting that somehow changed, but that wouldn't make any sense since to my knowledge the CL-1 doesn't need to be recognized by any sort of DAW. Again, thank you to everyone for putting in their two cents.

    I cannot find a decent specc' for the CL-1 but the current draw seems to be about 3mA and it will work on supplies down to 18V so I doubt the 48v PPower is the issue.

    ...................BUT!............Once again can I urge ALL musical peoples to GET A FRIGGING METER! The cheapest RadShack digital or annyloggy meter will tell you if you have phantom power twixt 2 and 1 and 3 and 1. Almost all meters have a mA range so having found the voltage, switch to current when, in theory you should get 7mA 'per leg' but 1/2 that would work for almost any mic or gadget.

    ggbriandee,

    Could you take a few pics of your setup with the connectors shown clearly and post them? (not sure how many posts are needed for noob to have permission to post pics(?))

    Secondly is the 2i2 plugged into a laptop or a desktop PC and have you tried different USB ports or even another computer if lucky enough to have one available? Where the interface and CL1 had once worked, have you changed computers? A few years back I had an older PC that for some reason could not supply adequate power to an interface if a mic was plugged in that required phantom power. The audio levels were low and had hiss when phantom was used. I was however able to get the interface to work using a powered USB hub.
    Mark.......
