The Shure ULXD2 is a handheld wireless transmitter compatible with ULX-D™ Digital Wireless Systems. With a rugged yet lightweight aluminum body and integrated antenna, the ULXD2 delivers uncompromising audio quality and RF performance, AES 256-bit encryption for secure transmission and advanced rechargeability options for professional sound reinforcement applications.
The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.
The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the "boomy" sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.- Features
Features
