Shure ULXD2/K8B Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (Black)

Product Overview

The Shure ULXD2/K8B is a professional digital handheld wireless microphone transmitter combining the ULX-D platform with the KSM8 Dualdyne cardioid dynamic vocal capsule in a black finish. Designed for demanding live sound reinforcement, touring, and commercial AV installations, this transmitter delivers 24-bit/48 kHz audio with AES 256-bit encryption and the unique dual-element dynamic capsule technology that controls proximity effect and off-axis attenuation. It is compatible with ULX-D and QLX-D receivers and supports advanced rechargeability for professional-grade fleet management.

Product Description

The KSM8 Dualdyne capsule uses two dynamic elements to provide outstanding control over proximity effect and superior off-axis sound rejection—performance characteristics that distinguish it from conventional single-element dynamic capsules. This makes the ULXD2/K8B particularly effective in high-SPL environments such as festivals, touring stages, and houses of worship where the singer's technique may vary. The aluminum ULXD2 body integrates Shure Gain Ranging for automatic dynamic range optimization, eliminating manual transmitter gain adjustments. AES 256-bit encryption supports secure audio transmission, and the optional SB900C rechargeable battery provides over 9 hours of runtime with real-time metering. Pair this transmitter with the Shure ULXD4 Single-Channel Wireless Receiver or ULXD4D Dual-Channel Receiver to complete the system.

Frequently Asked Questions

Q: What makes the KSM8 Dualdyne capsule different from a standard dynamic capsule?
A: The KSM8 uses two dynamic elements to control proximity effect and provide better off-axis sound rejection compared to conventional single-element dynamic capsules, resulting in more consistent vocal tone as the performer moves relative to the microphone.

Q: What receivers does the ULXD2/K8B work with?
A: This transmitter is compatible with all ULX-D receivers (ULXD4, ULXD4D, ULXD4Q) and the QLX-D receiver (QLXD4). Ensure frequency bands match between transmitter and receiver.

Q: Is there a nickel finish version of this transmitter?
A: Yes. The ULXD2/K8N provides the same KSM8 Dualdyne capsule in a brushed-nickel finish for applications where that aesthetic is preferred.

Q: Does the ULXD2/K8B support Wireless Workbench for system management?
A: Yes. When connected to a networked ULXD4 or ULXD4D receiver, the system integrates with Wireless Workbench 6 and supports AMX/Crestron control for enterprise AV deployments.
