    Hi, reasonably simple question which requires a simple answer...i hope.

    I am running an SM58 into a Motu Ultralite which is connected by firewire to my G4. I am recording spoken vocals into bias peak and only require a dry signal as all the effects will be applied after recording.

    My problem is that the levels i am getting are very low, even with the trim on the channel set at +24dB it barely tickles the signal meter. I know i don't need phantom power on the channel since it's a dynamic mic. Apparently the pad switch on the Motu can add up to an extra 36dB to the signal but this isn't having any effect.

    At the moment i have the shure connected via TRS into the combo jack input but would the lower impedance of an XLR connector make any difference?

    Do i need to pay close attention to the bit depth, sampling rate and clock source settings? What about balanced/unbalanced (clear that up?) there is only one insulating ring on the TRS connector so does that mean it is a mono jack. is this XLR to TRS cable even a suitable microphone cable...

    I'm sure there are some obvious solutions but any help will be greatly appreciated

    thanks in advance

    get a simple XLR to XLR cable
    thats 3 pins female to 3 pins male
    and use the Microphone input of the Motu Ultralite
    probably PAD off
    I think this should solve things quickly

    in Peak set the Audio for either
    48 K if you heading for video
    44.1 if you are heading for CDaudio
    24 bit will give you more headroom to work with
    which might help to get a result
    and then convert the files to 16 bit for Video or CD
    your video editor will do this when you import
    your CD writing software may do this automaticaly
    don't worry about this yet

    this is just a very general set of instruction so don't get excited
    and jump in with too much info

    we could talk about a couple of other issues about TRS and XLR cables which would lead to what impedance is and how PADs work
    and why the XLR isn't the impedance bit

    we can do that later

    this did solve things kev, thanks a lot.

    the xlr - xlr cable has given me a little bit more signal. The +24dB trim can take the levels up to clipping with the source i'm working with so i've got the input i need
