      Comments about Rolls MX51s Mini-Mix 2 Four-Channel RCA Mixer:

      We are using this mixer to switch between a crowd microphone for singing in our church with the main output which comes to us from RCA in the sound board. The box is steel and very rugged. Knobs are easy to control. Solid equipment. Only problem I had was moving the little switch for the phantom power. The tiny piece of plastic ended up going inside the container and I had to remove the case to get it back.
