DMK951N SERIES

DMK951NR Series dual channel microphone set, gives you freedom to perform up to 12 hours once fully charged.
It delivers superior durability against abuse use, and gives an extreme convenience to installers because of
pre-tuned crystal clear sound quality with minimal and tiny mechanics. The battery level & channel in use
indicating on FND give users a high-level usability, and also the multi-colored LED alerts enable to distinguish low
battery & proper channel pairing. It works with the less-crowded UHF frequency band, giving you clearer
interference-free sound.
DMK951NR Series channel allocation makes sure of superior sound quality, operating up to 30 rooms
simultaneously in case of 12 MHz bandwidth. Both mic channels have their own volume control and you can
either output both channels independently or together using the "mixed output" An auto mute circuit
eliminates the popping noise when switching the unit on or off. Our system is designed and manufactured to
be dependable, problem free, versatile and easy to use.
DMK951NR Series received a special award of “Best Seller” from most major distributors within shortest period.
