When I work strictly as a vocalist, I find my mic cable gets really twisted during the gig ... is there any kind of cable or adapter end that would prevent this?

Also, I use an XLR to 1/4" transformer to plug my mic into the Pa900 ... Is there a mic cable with an 'in-line' transformer built in so that I don't have to have 5 or 6 inches of transformer sticking out of the KB?
