Shure SLXD2/B87A Handheld Transmitter

Product Overview

The Shure SLXD2/B87A is a digital handheld wireless microphone transmitter for the SLX-D Wireless System, featuring the Beta 87A supercardioid condenser capsule for studio-quality wireless vocal performance in commercial AV installations and live event production. Audio engineers and AV integrators specify the SLXD2/B87A when a high-fidelity condenser capsule is required in a wireless SLX-D handheld configuration, whether as a standalone transmitter pairing with an existing SLXD4 receiver or as an upgrade to a complete system. The Beta 87A supercardioid pattern provides tight pickup and excellent off-axis rejection for maximum feedback control.

Product Description

The Shure SLXD2/B87A transmitter delivers the tonal quality of the Beta 87A condenser microphone over the 24-bit digital SLX-D wireless platform, combining studio-quality vocal transparency with professional RF reliability. The Beta 87A supercardioid condenser capsule provides extended high-frequency detail and a tighter polar pattern than cardioid dynamic options, making the SLXD2/B87A the preferred choice for lead vocals, corporate event production, and AV installations in reverberant commercial spaces where feedback rejection is critical. Compatible with SLXD4, SLXD4D, and SLXD4Q receivers within the same frequency band. Available in G58, H55, and J52 frequency bands.

Key Features

• Beta 87A Supercardioid Condenser Capsule — Delivers studio-quality vocal clarity with extended high-frequency response and a supercardioid polar pattern for tight pickup and maximum feedback rejection in commercial AV environments.
• 24-Bit Digital Wireless Transmission — Pairs with SLX-D receivers for transparent 24-bit digital audio that preserves the full frequency response of the condenser capsule.
• SLX-D System Compatibility — Compatible with SLXD4, SLXD4D, and SLXD4Q receivers within the same frequency band for single-channel and multi-channel wireless AV system configurations.
• Multiple Frequency Bands — Available in G58 (470–514 MHz), H55 (514–558 MHz), and J52 (558–602 MHz) for regional compliance and coordination with existing SLX-D wireless infrastructure.
• Supercardioid Off-Axis Rejection — Tighter polar pattern than standard cardioid designs reduces ambient noise and feedback pickup in reverberant auditoriums, hotel ballrooms, and multipurpose commercial spaces.
• Interchangeable Capsule Design — The SLXD2 transmitter body accepts Shure capsule adapters for future capsule upgrades without replacing the transmitter body.

Typical Applications

• Corporate event and all-hands room vocal reinforcement requiring condenser microphone clarity in a wireless configuration
• House of worship lead vocal systems specifying studio-quality wireless handheld performance
• Broadcast and live-streaming productions requiring condenser-quality wireless vocals
• Auditorium and performing arts venue wireless microphone upgrades from dynamic to condenser capsule
• Hotel ballroom and commercial event space wireless vocal systems with demanding audio quality requirements

Frequently Asked Questions

Does the SLXD2/B87A require phantom power?
No. The SLXD2/B87A transmitter provides internal power for the Beta 87A condenser capsule. No phantom power from the receiver or mixing console is required.

Which SLXD receivers is the SLXD2/B87A compatible with?
The SLXD2/B87A is compatible with all SLX-D series receivers (SLXD4, SLXD4D, SLXD4Q) within the same frequency band. Frequency band must match across all components in the system.

When should I choose the Beta 87A over a dynamic capsule for wireless use?
Choose the Beta 87A when extended high-frequency detail and vocal transparency are priorities—such as for lead vocalists, broadcast applications, or corporate event production in controlled acoustic environments. Dynamic capsules like the SM58 or Beta 58A are preferable in high-SPL or less controlled acoustic environments.

Can I upgrade my existing SLXD2 transmitter body to use the Beta 87A capsule?
The SLXD2/B87A ships as a complete transmitter body with Beta 87A capsule. The SLXD2 transmitter body accepts interchangeable Shure capsule adapters, so capsule changes are possible in the field.
