Product Description
Shure ULXD2/SM87 ULX-D Series Digital Wireless Handheld Transmitter
With an interchangeable SM87A microphone cartridge, the ULXD2/SM87 delivers uncompromising audio quality and RF performance, and AES 256-bit encryption for secure transmission. The ULXD2/SM87 Handheld Wireless Microphone Transmitter works with ULX-D Wireless Systems, and offers over 12 hours of continuous battery life with a Shure rechargeable battery or 11 hours with a standard alkaline battery. The Shure SM87A microphone is a professional-quality, handheld condenser microphone for use in sound reinforcement, broadcasting, and studio recording installations. Its supercardioid polar pattern provides greater rejection of unwanted sound sources, making it ideal for miking individual instruments in a multi-microphone setting or for miking single sources in a reverberant or noisy environment. Includes ULXD2/SM87, 2 AA batteries, microphone clip, zipper bag, and user guide.
