The Shure SLXD24/B58 wireless handheld microphone system offers presenters and performers a dependable, easy-to-set-up solution featuring crystal-clear, digital sound quality. Built around a rugged, single-channel, half-rack receiver with removable antennas, this system is ideal for portable rigs or long-term installations in small- to medium-sized venues, event spaces, conference rooms, houses-of-worship, and educational facilities.

Superior Sound Quality and Reliability

High-Quality Digital Audio

The SLX-D operates in the UHF band to transmit high-quality, 24-bit digital audio with over 120 dB of dynamic range, ensuring crisp, detailed sound.

Reliable RF Signal

Utilizing Digital Predictive-Switching Diversity, the system protects the transmission from interference and delivers a solid, reliable RF signal without dropouts.

Handheld Transmitter with Beta 58A Capsule

Durable and Versatile Design

The SLXD2 handheld transmitter features an interchangeable microphone capsule design and is equipped with a Beta 58A dynamic capsule. This supercardioid capsule focuses on speech and helps reduce feedback on loud stages. The lightweight metal transmitter has a selectable 1/10mW RF power output and a transmission range up to 330 feet.

Long Battery Life

The transmitter provides up to 8 hours of operation on two AA batteries or an SB903 rechargeable battery (available separately).

All-Metal Rackmount Receiver

User-Friendly Interface

The SLXD4 receiver features an intuitive LCD interface with meters for RF, battery status, and audio output. It offers 60 dB of gain control and both mic/line XLR and 1/4″ instrument outputs.

Simplified Setup

The receiver includes automatic frequency scanning and IR sync to easily link the transmitter and receiver to the same frequency. With an Ethernet port, setting up multiple systems is fast and easy via coordinated frequency scans from a single receiver.

Expandable System

Multiple Channels

With up to 32 mic channels available simultaneously, the SLX-D is ready to expand as your needs grow. The system supports up to 10 compatible systems per 6 MHz TV band and 12 systems per 8 MHz band.

Networking Capabilities

Ethernet networking allows coordinated group scanning between multiple receivers from a single location, supporting TCPI command streams from third-party companies such as AMX and Crestron.

Handheld Transmitter Features

Comfortable and Informative Design

The SLXD2 handheld transmitter offers a lightweight, durable aluminum housing and an LCD to show essential information. The Beta 58A capsule is designed for close-up vocals, featuring a supercardioid polar pattern for high gain before feedback and maximum isolation from other sound sources.

Interchangeable Capsules

The transmitter’s interchangeable capsule design allows for a variety of optional dynamic and condenser mic capsules with varying pickup patterns, including the Beta 87A, SM58, and KSM8.

Dependable Performance and Transparent Sound

Spectrum-Efficient Transmission

The SLX-D delivers 24-bit digital audio with a fast transient response and over 120 dB of dynamic range. Operating in the H55: 514 to 558 MHz UHF band with a 44 MHz tuning range and 1760 selectable frequencies, the system avoids potential Wi-Fi interference in the 2.4 GHz band.

Low Latency

With a low latency of 3.2 ms, the system is ideal for events that require live sound reinforcement.

Ready to Rackmount

Robust Construction

Housed in a tough, half-rack metal chassis with detachable antennas, the SLXD4 receiver is perfect for A/V installations or portable rackmount rigs, ready for travel to meetings or events.

Easy Setup and Control

The SLX-D is designed for outstanding sound in small- to medium-sized spaces, featuring intuitive front-panel controls and a high-contrast LCD screen with audio and RF meters. The auto-scan function seeks out the cleanest available frequency, with easy linking via infrared.

Optional Rechargeable Battery Management

Cost-Effective and Eco-Friendly

Adding the SB903 lithium-ion rechargeable battery with an SBC10-903 single charger or an SBC203 dual-docking charger offers a cost-effective, environmentally friendly alternative to disposable AA batteries. The transmitter displays the remaining battery life in hours and minutes when powered by an SB903.

Enhancing System Reliability

Extended Range and Protection

Adding UA874 active antennas or PA805SWB passive antennas increases the range and protection against interference. The UA844+SWB antenna distribution system allows more on-air channels in less setup time.

Variety of Microphones and Transmitters

Adapting to Evolving Needs

Shure offers a bodypack transmitter with various lavalier and headset microphones. Options include the WL183 (omnidirectional), WL185 (cardioid), WL184 (supercardioid), miniature WL93, subminiature MX150, discreet MX153 earset, and durable PGA31 headset microphone for active performance.
