We are proud to introduce the allnew RWM72U. The price is reasonable, but the performance is what puts these micson another level. There were a few goals when developing this product. Sensitivity Isn’t it frustrating when buying a microphone that when you sing or talk, themic needs to practically be in your mouth? We prevented that with the RWM72Ubecause we use a higher sensitivity cartridge that has great performance andsound quality. Long range and performance We wanted a microphone system that allows you to walk far away from the receiverwhile moving and jumping around without any dropouts or cutouts. whether you aresinging on stage or making speeches this microphone system really shines.Reliability is something you will never have to worry about. Battery life We wanted a highly efficient microphone that will not consume its batteryquickly. Our mics have a 10-hour battery life! No unwanted noises We wanted to be sure that the mic does not produce unwanted noise so we added anoise filter that prevents unwanted background or popping noises. Flexible Outputs Each microphone has individual volume controls. The RWM72U also has a mix outputif you want to connect to a single channel of a mixer where you would controlthe mic mix. There are also individual outputs so you can plug Mic A into onemixer channel and mic B into another mixer channel in case you want to have 2different sound mixes on each mic.
