"I want to tell you that I HIGHLY recommend this to any upcoming and even veteran engineer, this thing works great. It has helped my new Monitor engineers with setup and operation of our Monitor system, it has cut the setup time in half, no more squealing and ringing for an hour to make it right. I'm going to order another one for FOH use as well. This is a great piece of gear!!!!! ...and you can quote me." ... Don Lanier, NPS Productions
