sebatron - presonus firebox - mac: not enough volume

    I'm using a Rode K2 and Peluso CEMC 6 to record a guitar thru my Sebatron into the TRS in's of the Presonus Firebox and then into my powerbook.

    Here's my issue: Not enough input/recording volume. I've got the output on the Sebatron around 6 in hopes to get more volume, but I barely end up with any reading on the garageband meter, so I have to use a boosting effect in garage band or crank up the wav file with something like Audacity. This seems like a rig job, so I was wondering if anyone uses a sebatron with a Firebox and is able to get some good volume on the front end. The Firebox comes with this little mixer software, and all channels are cranked to "U", but still no luv.

    If I add my mackie mixer to the chain I can get more volume, but then I introduce noise because that's another pre in the mix.

    (btw, the reason I'm using Garabe Band instead of something like Cubase is because I only record like one track, maybe two, so I would imagine I don't need all the bells and whistles of the nicer software.)

    Can you switch the line inputs of the Firebox between -10 and +4 db? If so try playing with that.
    If not.... use the Instrument ins on the front... the centre of the "multi-socket" and give it some gain there.

    I read in a few other posts about the sebatron (or any outboard pre for that matter) that I'm not supposed to add another pre in the chain, because that adds noise among other things. But maybe there's not much more I can do with budget gear like the firebox...

    I actually send my Seb through a Mindprint DI-port in that way with no problems at all.
    You shouldn't need to turn the Firebox gains up very far at all.... I only have the DI-port on about 2.

    thanks, Mark. I'll give that a whirl tonight.

    I have to take your word for it since it sounds like you've got such a similar setup. Have any trouble with noise?

    Well, I did a very simple noise floor test when I first got my Buzz Audio SSA1.1 pre, which is super clean.
    I plugged in a B&K4007, cranked it up full and listened with Beyer DT770pro headphones. All I could hear was a bit of ambient noise..... no hiss..... no hums......
    Tried a couple of my cheaper mics (Beyer Opus81, MXL V67M.....) and found out why cheap mics are cheap lol.

    Haven't tried that with the Seb, but the rest my my signal chain is quiet, so I know that side of things won't be a problem..... and I wouldn't expect a tube pre to be totally silent.

    Peluso CEMC6s

    Hi Dave, How are you getting along with those CEMC6 mics? Are they working out OK for you? I have a matched pair kit coming in this Friday from Soundpure. I will be using them through the Avalon AD2022, so I will let you know how that works out. But, I wanted to know what your impressions were and to, perhaps, boost my moral about the purchase, thanks!
