Details: Shure ULX-D digital wireless offers uncompromising 24-bit audio clarity and extremely efficient RF performance with single, dual, and quad Channel receivers for any size professional sound reinforcement application. Scalable, intelligent hardware delivers the best performing digital wireless available, with a wide selection of trusted Shure microphones to choose from. Unmatched spectrum efficiency enables a dramatic increase in the number of simultaneous active transmitters on one TV channel, with a rock-solid signal over the entire range. Optional rechargeable accessories eliminate the need for disposable batteries while offering extended run time and metering accuracy in hours and minutes. For secure transmission, All ULX-D components include AES-256 encryption. Generations ahead of any other available system in its class, ULX-D brings a new level of performance to professional sound Reinforcement. Fcc consumer alert (U.S.) most users do not need a license to operate This wireless microphone system. Nevertheless, operating This microphone system without a license is subject to certain restrictions: The system may not cause harmful interference; It must operate at a low power level (Not in excess of 50 milliwatts), and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating the use of wireless microphone systems, and these rules are subject to change.
