Wii speak accessory-
If you own rock band for the wii and have the "wireless adapter" in, take it out, that's the same spot that the wii speak accessory needs to be plugged into.
If not, the correct plug-in is the one on the very top-left corner (when looking directly at the back)
Rockband micrphone-
This accessory must be plugged into the first or second slot of the rock band "wireless adapter"

you need a wii remote for the mic just like the guitar, drums and bass.
Any USB Microphone
Just hook up the microphone's plug into the the back of the Wii and on the World Tour game select vocals. You have to have a separate Wii remote for each instrument... It's annoying because this information isn't written in the instructions. The microphone plugs into the USB port at the top of the back of the console. The unfortunate part is that you need a controller to assign the microphone. That means if you only have 2 controllers, you can only use 2 of the instruments. I sort of see why (so you can assign the characters, etc.), but that shouldn't have been a limitation to use the microphone. You can get any wired microphone like the one from rock band and plug it in in the back of the wii and rock on nub!!!
The microphone should probably be plugged into the Memory Card slots (in the top of the Wii) or the USB ports. (at the back)
No, net necessarily. You do need a Wii microphone
