Shure QLXD2/K8B Black QLXD HH Transmitter with KSM8 capsule

Product Overview

The Shure QLXD2/K8B is a QLD-D digital wireless handheld transmitter in a black finish, fitted with the KSM8 dual-diaphragm dynamic capsule, designed for wireless vocal applications in music venues, houses of worship, and commercial AV installations. Built on the same QLXD2 platform delivering 24-bit digital audio and 100-meter range, the K8B variant pairs the digital wireless advantage of the QLXD system with the live vocal performance characteristics of the KSM8 capsule. The all-metal, black-body construction integrates cleanly into dark-stage and black-trim production environments.

Product Description

The QLXD2/K8B combines the proven QLXD2 digital wireless transmitter body with the KSM8, Shure's dual-diaphragm dynamic capsule engineered for live vocal applications. The KSM8's dynamic design handles high SPL sources without distortion, while the QLD-D digital transmission preserves audio transparency that analog wireless systems cannot match. One-touch IR sync with a paired QLXD4 receiver makes frequency coordination straightforward in multi-channel installations. The black body finish distinguishes this model from the nickel-finish QLXD2/K8 and complements black-trim AV infrastructure and staging. The interchangeable RPW capsule platform allows the transmitter to accept other Shure RPW capsules as application needs change. See also the Shure QLXD2/B87C for a condenser capsule alternative in the QLXD2 platform.

Key Features

• KSM8 Dual-Diaphragm Dynamic Capsule — Shure's KSM8 dynamic capsule uses dual-diaphragm construction to deliver detailed, articulate vocal reproduction with strong gain-before-feedback performance suited to live stage environments.
• Black-Body Finish — Matte black all-metal construction integrates with black-trim staging, dark-stage production environments, and commercial AV installations where visual discretion is required.
• 24-Bit Digital Audio — Transparent QLD-D digital wireless transmission maintains the full fidelity of the KSM8 capsule without the noise and artifacts of analog wireless systems.
• 100-Meter Operating Range — Provides clear, uninterrupted signal coverage up to 100 m (330 ft) across large venues and multi-zone commercial AV deployments.
• One-Touch IR Sync — Infrared sync with the paired QLXD4 receiver enables fast frequency coordination at system setup, reducing deployment time in multi-system installations.
• Interchangeable RPW Capsule System — Compatible with Shure's full RPW capsule lineup including SM58, Beta 87A, Beta 87C, KSM9, and others, allowing capsule changes without replacing the transmitter body.
• All-Metal Construction — Touring-grade metal housing delivers the durability required in high-use commercial AV and performing arts environments.
• Optional SB900C Rechargeable Battery — Lithium-ion rechargeable option provides up to 10 hours of runtime with hours-and-minutes battery status reporting for production planning.

Frequently Asked Questions

What is the difference between the QLXD2/K8B and the QLXD2/K8?
The QLXD2/K8B features a black-body finish while the QLXD2/K8 uses a nickel finish. Both use the same KSM8 dual-diaphragm dynamic capsule and QLXD2 transmitter electronics. The RPW174 black KSM8 wireless capsule is specifically designed for black-body Shure transmitters.

Which receiver pairs with the QLXD2/K8B?
The QLXD2/K8B requires a Shure QLXD4 single-channel or QLXD4Q quad-channel receiver in the same frequency band for system operation.

Why choose the KSM8 dynamic capsule over a condenser capsule for live applications?
Dynamic capsules typically handle very high SPL levels without distortion and are generally more resistant to humidity and environmental factors, making them a practical choice for demanding live stage and house of worship environments. The dual-diaphragm construction of the KSM8 provides higher fidelity than traditional single-diaphragm dynamic capsules.

Is the QLXD2/K8B suitable for commercial AV integration?
Yes. The QLD-D system's digital audio quality, efficient RF spectrum usage, and IR sync setup make it well-suited for fixed-installation commercial AV environments. The black finish further suits installations requiring discrete hardware aesthetics.
