Shure ULXD2/KSM9 Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule

The Shure ULXD2/KSM9=-J50A is a handheld wireless microphone transmitter that pairs perfectly with Shure ULX-D receivers. It arrives fitted with the renowned KSM9 dual diaphragm condenser capsule, so vocalists and presenters get studio level clarity on stage or in broadcast settings.

The capsule allows users to switch between cardioid and supercardioid pickup patterns, making it easy to adapt to different room acoustics, floor wedges, or in-ear monitors. Whether you are mixing front-of-house for a touring act, reinforcing speech in a conference hall, or leading worship, this flexibility helps keep feedback under control while preserving natural tone.

Audio stays pristine thanks to 48 kHz and 24-bit digital conversion carried over UHF frequencies. A maximum range of roughly 328 feet lets performers move freely, while 256-bit AES encryption keeps the signal secure in corporate or government environments that demand confidentiality.

The housing is crafted from aluminum, a material that keeps weight down without sacrificing strength, so the transmitter feels solid yet comfortable during long sets. Power options include Shure rechargeable packs that can deliver up to 12 hours of runtime, and the front panel LCD gives instant feedback on battery status, frequency, and RF output, which can be set to 1, 10, or 20 milliwatts to match venue requirements.
