Shure SLXD2/B58 Handheld Transmitter

Product Overview

The Shure SLXD2/B58A is a digital handheld wireless microphone transmitter for the SLX-D Wireless System, equipped with the Beta 58A supercardioid dynamic capsule for high-SPL wireless vocal performance in live sound, installed AV, and commercial event production. AV integrators and audio engineers select the SLXD2/B58A when a wireless handheld with tight supercardioid pickup and maximum feedback rejection is required for house of worship, auditorium, or conference room deployments. Compatible with SLXD4, SLXD4D, and SLXD4Q receivers within the same frequency band.

Product Description

The Shure SLXD2/B58A pairs the Beta 58A supercardioid dynamic capsule with the 24-bit SLX-D digital wireless platform for reliable wireless vocal transmission in high-SPL commercial environments. The Beta 58A’s neodymium magnet and supercardioid polar pattern provide a tighter pickup pattern than standard cardioid dynamics, reducing feedback and ambient noise in active loudspeaker environments. This makes the SLXD2/B58A the appropriate choice for conference rooms, auditoriums, and houses of worship where both wireless reliability and feedback control are critical specifications. Available in G58, H55, and J52 frequency bands to match regional spectrum availability and existing SLX-D infrastructure.

Key Features

• Beta 58A Supercardioid Dynamic Capsule — Neodymium magnet design with a supercardioid polar pattern delivers tight pickup, high SPL handling, and maximum feedback rejection for live commercial AV and event production environments.
• 24-Bit Digital Wireless Transmission — Transmits 24-bit digital audio when paired with SLX-D receivers, providing transparent wireless performance across the vocal frequency range.
• SLX-D System Compatibility — Compatible with SLXD4, SLXD4D, and SLXD4Q receivers within the same frequency band for flexible single- and multi-channel wireless system configurations.
• Multiple Frequency Bands — Available in G58 (470–514 MHz), H55 (514–558 MHz), and J52 (558–602 MHz) for regional spectrum compliance and coordination with existing wireless infrastructure.
• High SPL Handling — The Beta 58A dynamic capsule handles high sound pressure levels without distortion, suitable for close-miking vocalists and presenters in loud reinforced environments.
• Interchangeable Capsule Design — The SLXD2 transmitter body accepts Shure capsule adapters, enabling future capsule upgrades without replacing the entire transmitter.

Typical Applications

• House of worship live vocal reinforcement in high-SPL environments with active monitor systems
• Auditorium and multipurpose venue wireless handheld microphone systems requiring supercardioid feedback rejection
• Conference room and all-hands room presenter wireless microphone with feedback control requirements
• Commercial event and hotel ballroom wireless vocal systems with challenging acoustic environments
• Government and institutional venues requiring reliable wireless handheld microphone infrastructure

Frequently Asked Questions

What is the difference between the Beta 58A and SM58 for wireless installations?
The Beta 58A uses a supercardioid polar pattern versus the SM58’s cardioid, offering tighter pickup and higher feedback rejection—critical in high-volume live environments with active monitor systems. The Beta 58A also handles higher SPL and has a brighter frequency response. The SM58 is easier to use for varying mic technique since the cardioid pattern is more forgiving.

Which SLXD receivers work with the SLXD2/B58A?
The SLXD2/B58A is compatible with all SLX-D receivers: SLXD4 (single), SLXD4D (dual), and SLXD4Q (quad), within the same frequency band.

Can the SLXD2/B58A be used as a standalone transmitter with an existing SLXD4 receiver?
Yes. As long as the SLXD2/B58A and your SLXD4 receiver share the same frequency band, the transmitter will integrate directly into your existing SLX-D system without additional configuration.

Does this transmitter require any special power supply?
The SLXD2/B58A transmitter operates on standard AA batteries. No special power supply or phantom power is required from the receiver or mixing console.
