Shure QLXD2/BETA87C Handheld Wireless Microphone Transmitter

Experience Simple, Elegant Wireless With The Shure QLXD2/BETA87C Handheld Wireless Condenser Microphone Transmitter.

With professional level features and increased simplicity in operation, at Yandas we have found that the QLXD digital wireless systems are ideal for mid-size events and installations across the board. New wireless applications have created situations with increased complexity and scale which require more robust solutions. With immense networking capabilities and transparent 24-bit audio quality, Shure QLXD has taken professional level wireless into the digital realm to achieve clear, problem-free, wireless audio in even the most complex sound situations. With features such as automatic channel scanning to deploy frequencies to transmitters on a clean channel and AES-256 bit encryption, the Shure QLXD produces top notch wireless functionality for nearly any application. 

Simple, Powerful Digital Wireless.

Compatible with the Shure QLXD4 wireless diversity receiver, the Shure QLXD2/BETA87C handheld microphone transmitter features the BETA87C condenser style microphone cartridge with a cardioid polar pattern. The condenser style microphone creates crisp, studio vocal reproduction, while the cardioid polar pattern produces a warm, wide directional response for accurate and natural sound production. Simple to use interface, easy transmitter to receiver pairing, and remote monitoring options make the QLXD digital wireless system an incredibly intuitive, professional quality wireless system.
