Hi, Iíve recently tried a usb microphone (SE USB1000A) on 3 different macs, but canít get the input volume anywhere near as high as it needs to be.

Iíve set the microphoneís input volume to maximum in the sound, system preferences, but the test bar barely registers a sound unless you sing with the microphone pressed to your mouth. The volume in garageband is therefore unusable, because if you press the mic to your mouth while recording, the quality is terrible (significantly worse than the built in mic).

After altering the settings on a PC I could get a decent volume, but want to use it with a mac. Can anyone help?
