The Shure ULXD2/SM87 is a digital handheld wireless microphone transmitter compatible with ULX-D and QLX-D receivers. It comes equipped with the SM87A supercardioid condenser capsule designed to withstand extreme sound pressure levels, while still delivering a remarkably smooth frequency response for vocal performers and presenters. The capsule features a supercardioid polar pattern that rejects off-axis background noise, helping to reduce feedback.
With rugged, yet lightweight aluminum housing, the ULXD2/SM87 transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options for professional sound-reinforcement applications.
