Hi Folks, Has anyone hear got any info on the following mike as for recording uses ? SENNHEISER MD 21 Just purchased a couple today at a Church Clearence sale they where part of the Church PA Got the 2 mikes an old valve amp little speakers for $210 Aus. They have small 3pin male sockets so will have to make up some adapter leads.They seem to go all right with the old PA system but when I tried them with the mic leads they came with (the other end seemed normal XLR connection) on a powered monitor there was nothing but a hum. So perhaps the old leads aren't wired the same ?Hopefully someone can help me out re these old mic's. I was even thinking of using one for playing harmonica through.They kinda look like a cool harp mike. Thanks for taken a look Cheers Slim.
