A:AnswerOnly the base will swivel. All joints do not swivel, they will only bend in the direct the arm points. So make sure you MIC can swivel on its own and make sure if you use cable management path. To leave slack for bending cable as it will break copper cables if you dont. Happen to me once and leason learned.
A:AnswerYes, but the weight of the arm itself counts against its own capacity which is very misleading. The mic in the photo shows the Shure SM7dB which is the mic I have. The arm falls. Very easily even. This is NOT a secure arm for this microphone. I recommend finding something that supports atleast 5.5 lbs or more.
A:AnswerNo. You will need a way to come out of the mic. So if you don't have an interface or a mixer, then you will need to get one or an XLR to USB-C Phantom Power converter that will send the signal to your computer.
