Shure ULXD2/K8B – Digital Handheld Transmitter with KSM8

Product Overview

The Shure ULXD2/K8B is a digital wireless handheld microphone transmitter built for the ULX-D Digital Wireless System, pairing a rugged aluminum handheld body with the KSM8 Dualdyne cardioid dynamic microphone capsule. It is designed for commercial AV deployments — conference rooms, houses of worship, training rooms, and broadcast studios — that need dependable RF performance alongside AES 256-bit encrypted digital wireless audio. The KSM8 capsule delivers a controlled proximity effect and reduced off-axis coloration, giving presenters and vocalists clearer pickup than a standard dynamic capsule. This transmitter requires a ULXD4 receiver to complete the wireless system and is supplied in the G50 frequency band (470 to 534 MHz).

Product Description

Commercial AV integrators specifying a digital wireless handheld microphone transmitter for a conference room, all-hands room, or house of worship need RF reliability and vocal clarity that stand up to daily use, and the ULXD2/K8B is built around both. The Dualdyne dual-diaphragm design in the KSM8 capsule reduces the proximity-effect bass buildup that occurs when a presenter or singer works close to the microphone, and it also lowers off-axis pickup coloration so the mic sounds consistent whether the speaker holds it dead-on or at an angle. On the RF side, the ULXD2 transmitter uses always-available AES 256-bit encryption, meeting the security requirements common in corporate boardrooms, government meeting spaces, and other environments where unauthorized audio interception is a concern. Shure's Gain Ranging technology automatically adjusts the transmitter's internal gain structure to the input signal, so AV technicians do not have to manually set gain for each presenter or performer before a session starts. The transmitter's rugged, lightweight aluminum body and integrated antenna are built for the wear and tear of daily commercial use — training rooms, multi-purpose rooms, and auditoriums that see the microphone handled by many different users. Power comes from user-supplied AA batteries or an optional Shure SB900C rechargeable lithium-ion battery pack, giving facilities managers flexibility between low-cost AA operation and precision-metered rechargeable battery life for high-use rooms. As a component of the ULX-D digital wireless system, the ULXD2/K8B requires pairing with a compatible ULXD4 receiver, and integrators should confirm the transmitter's frequency band matches the receiver and any other wireless devices operating in the same RF environment. For commercial deployments that need consistent vocal reproduction, dependable digital wireless transmission, and encryption-grade security, the ULXD2/K8B is a strong choice for boardrooms, auditoriums, and broadcast studios alike.

Frequently Asked Questions

What receiver does the ULXD2/K8B need?
The ULXD2/K8B is a handheld transmitter only — it requires a Shure ULXD4 receiver on the same frequency band to complete the ULX-D digital wireless system.

Can I use a different microphone capsule on this transmitter body?
Yes. The ULXD2 handheld transmitter body accepts other interchangeable Shure wireless microphone cartridges, so integrators standardizing on ULXD2 bodies can swap capsules like the KSM8, SM58, or Beta 87A as needed.

Is this transmitter secure enough for government or corporate boardroom use?
Yes. The ULXD2/K8B uses always-on AES 256-bit encryption that cannot be disabled, which meets the security requirements common in corporate boardrooms and government meeting spaces.

What batteries does the ULXD2/K8B use?
It runs on standard AA batteries or the optional Shure SB900C rechargeable lithium-ion battery pack, which provides over 12 hours of runtime with precision battery metering.

Does frequency band matter when ordering additional units?
Yes. Confirm that any additional transmitters, receivers, or antenna combiners in the same installation share a compatible frequency band with this G50 (470–534 MHz) unit to avoid RF conflicts.

What accessories are available for the KSM8 capsule?
Creation Networks stocks the Shure AK8C carrying pouch and replacement KSM8 microphones such as the Shure KSM8/B for spare-capsule planning.

Can I charge multiple transmitter batteries at once for a large deployment?
Yes, facilities running several ULXD2 transmitters can use a networked charging station such as the Shure SBC850 to charge multiple SB900-series batteries simultaneously.

Does Shure warranty the ULXD2/K8B?
The ULXD2/K8B carries Shure's standard manufacturer warranty for wireless transmitters; contact Creation Networks support for current warranty terms and RMA assistance.
