My sm58 has a low
This could be any of several things. IF the audio output of the mic is at a normal level then the first thing to check is the mic cable. I have several things to discuss so read all of this and then test.
First, I found six BRAND NEW XLR cables were wired wrong... the vendor had 13000 of them in stock and was going to have to check them all. The cables appear to work, but had the shield and one signal wire in the wrong place so the line was NOT a twisted pair balanced as required, but instead a plain coax. I had to repair these at a venue when I discovered the problem. Please google the correct XLR configuration. The pin numbering is NOT what one would expect. You cables (open the ends and look) should have the shield tied to pin 1 which is one of the side pins. Mine they had the shield on the middle pin or apex of the triangle.
Second, there are COUNTERFEIT Shure SM58's being sold. Read about that at google... If you unscrew the screen and find a label on the side of the element, the mic is a fake... Now there are two qualities of fakes... some perform ABOUT as good as the genuine, and others don't even have the balancing transformer.
If the hum is only there while handling the mic, the ground to the shell is not connected... this is mainly a mechanical connection. You can extract the XLR male plug from the bottom of the mic by removing the side screw and gently pull out by grabbing one of the pins. Also you can verify the wire colors as the fakes use the wrong color wires.
Noise problems are my specialty so if you need further help send a comment to me.

Boot Error Shutting Down Sony NWD-B103
Had a similar problem with the B103F. Not sure it will work for the non F version.
Goto Sony's support site at http://www.sony-asia.com/section/support.
Search model - NWD-B103F (non F is not listed)
Look at the "latest downloads" and select the "firmware update program". (alternately you could first select the "download" section and then select the model.)
Run (without the unit plugged) and when asked plug the unit. To be on the safe side, ask it also to format the data section.
When finished, the unit should be OK.
