Shure SLXD24/K8B-H55 Digital Wireless Vocal System with KSM8 Handheld Transmitter

Product Overview

The Shure SLXD24/K8B is a professional single-channel digital wireless vocal system for installed AV, live sound, and broadcast applications, combining the SLXD4 digital receiver with the SLXD2/K8B handheld transmitter featuring the KSM8 dual-diaphragm cardioid dynamic capsule. The KSM8 delivers a flat, extended frequency response that captures vocals and speech with broadcast-quality accuracy, making the SLXD24/K8B digital wireless system the preferred choice for discerning AV integrators and audio engineers who require exceptional vocal transparency in conference rooms, auditoriums, and houses of worship. The system delivers 24-bit digital audio with over 120 dB of dynamic range.

Product Description

The Shure SLXD24/K8B pairs the proven SLX-D digital wireless platform with the KSM8—a dual-diaphragm cardioid dynamic microphone engineered for natural, high-fidelity vocal reproduction. The KSM8’s neodymium magnet and dual-diaphragm design provide extended frequency response and reduced proximity effect, which is particularly valuable in close-miking applications such as podium installations and handheld presenter use in large rooms. The SLXD4 half-rack receiver delivers Digital Predictive Switching Diversity, 3.2 ms latency, and supports up to 32 simultaneous SLX-D systems—making it scalable for multi-microphone AV deployments in conference centers and government spaces. Both XLR (mic/line) and ¼" instrument outputs integrate directly with standard AV signal chains.

Key Features

• KSM8 Dual-Diaphragm Cardioid Dynamic Capsule — Engineered with a dual-diaphragm design and neodymium magnet for extended frequency response and a flat, natural vocal character that outperforms typical single-diaphragm dynamic capsules.
• 24-Bit Digital Audio with 120+ dB Dynamic Range — Transparent digital audio resolution with over 120 dB of dynamic range preserves the full fidelity of vocal and speech content without compression artifacts.
• 3.2 ms System Latency — Low latency digital transmission eliminates audible delay in live reinforcement and supports in-ear monitoring applications requiring precise timing.
• Digital Predictive Switching Diversity — Proactively selects the cleaner of two antennas before signal degradation occurs, maintaining stable wireless reception in complex commercial RF environments.
• Up to 32 Simultaneous Systems — Spectrum-efficient SLX-D transmission supports high-channel-count wireless deployments in large conference centers, auditoriums, and multi-room AV systems.
• SLXD4 Half-Rack Receiver with LCD Metering — All-metal half-rack form factor includes an LCD interface with RF, battery, and audio metering for continuous system monitoring during live events and installed operation.
• XLR and ¼" Outputs with 60 dB Gain Control — Flexible output options and 60 dB of gain adjustment enable direct connection to professional mixing consoles and DSP audio processors.

Typical Applications

• Boardroom and executive conference room wireless microphone systems requiring high vocal fidelity
• Broadcast studio and recording environment wireless vocal pickup
• House of worship speech and vocal reinforcement for lead vocalists and pastors
• Auditorium and all-hands room AV installations with demanding audio quality requirements
• Government and institutional spaces requiring broadcast-grade wireless audio

Frequently Asked Questions

What makes the KSM8 capsule different from a standard dynamic microphone?
The KSM8 uses a dual-diaphragm design with a neodymium magnet to deliver extended frequency response and a flatter, more natural vocal character than single-diaphragm dynamic microphones. This results in more transparent speech reproduction suited to broadcast-quality AV installations.

Is the SLXD24/K8B compatible with multi-channel SLXD receivers?
Yes. The SLXD2/K8B transmitter included in this system is compatible with SLXD4D (dual-channel) and SLXD4Q (quad-channel) receivers within the same frequency band, allowing integration into larger multi-channel SLX-D wireless systems.

How many systems can operate simultaneously in the same venue?
The SLX-D system supports up to 32 simultaneous wireless systems per frequency band, enabling high-channel-count deployments in large auditoriums and conference centers.

Does the SLXD4 receiver support remote antenna placement?
Yes. The SLXD4 receiver includes antenna ports compatible with Shure UA series antenna distribution systems for remote antenna deployment, improving RF coverage in large or architecturally complex installation environments.

What is the warranty on the SLXD24/K8B system?
Shure wireless systems carry a two-year limited warranty on manufacturing defects. Service and repairs are available through Shure authorized service centers.
