Shure AD2TA/B58=-G57 – Axient Digital Handheld Transmitter, Beta 58A, G57 (TAA)

Product Overview

The Shure AD2/B58 Axient Digital handheld wireless microphone transmitter (AD2TA/B58=-G57) is a professional-grade handheld transmitter for the Axient Digital system, operating in the G57 band (470–616 MHz) with a built-in Beta 58A dynamic supercardioid capsule and full TAA compliance. Designed for commercial AV installations, broadcast studios, houses of worship, and government audio reinforcement, the AD2/B58 delivers 146 MHz of ultrawide UHF tuning, AES-256 encryption, High Density mode, and an interchangeable capsule design that allows the Beta 58A to be replaced with other Shure RPW-series capsules as application needs change. See also the Shure RPW122 Beta 87C Wireless Replacement Capsule if you need a condenser capsule option for this transmitter body.

Product Description

Built for commercial AV system designers and integrators deploying professional wireless microphone systems in demanding RF environments, the AD2/B58 combines the proven Beta 58A dynamic supercardioid capsule with the full performance of the Axient Digital wireless platform. The Beta 58A features a neodymium magnet for high signal-to-noise output, a brightened midrange and bass roll-off that controls proximity effect for close-mic vocal applications, and a supercardioid polar pattern that provides maximum isolation from off-axis sound sources and strong gain before feedback. The transmitter body supports selectable RF output power (2/10/35 mW), standard and High Density transmission modes, Automatic Gain Control, and frequency/power lockout functions for live event security. Wireless Workbench 6 integration enables centralized RF coordination, spectrum scanning, and remote battery monitoring. The interchangeable capsule design means the transmitter body can be repurposed across different applications simply by swapping the capsule. Ships TAA-compliant for federal government procurement.

Key Features

• Beta 58A Dynamic Supercardioid Capsule — Delivers brightened midrange response and controlled proximity effect for close-mic vocal applications, with neodymium magnet providing high signal-to-noise output and a hardened steel-mesh grille that resists wear in demanding live environments.
• Interchangeable Capsule Design — The Beta 58A capsule is field-replaceable with any Shure RPW-series wireless capsule (including Beta 87A, Beta 87C, KSM8, KSM9, SM58, and others), allowing a single transmitter body to serve multiple applications across a commercial AV installation.
• G57 Band Operation (470–616 MHz) — Operates across 146 MHz of ultrawide UHF tuning in the standard professional wireless range, providing excellent frequency agility for coordination in complex commercial AV environments.
• High Density Mode — Supports high-density simultaneous channel deployment for large-scale commercial AV, broadcast, government, and house of worship wireless systems.
• AES-256 Encryption — Standard on every unit, providing secure audio transmission for government, enterprise, and legal AV environments without additional licensing.
• Selectable RF Output Power (2/10/35 mW) — Three power levels enable precise balance between transmission range and channel density for any commercial installation.
• Automatic Gain Control — Adjusts input levels in real time across different talent and vocal dynamics, maintaining consistent signal quality without manual gain-staging between performers.
• Rechargeable Battery Option — Accepts the optional Shure SB900A rechargeable Li-ion battery for up to 9 hours runtime, with networked charging via SBC220 or SBC840 chargers integrated into Wireless Workbench 6.
• IR Sync — One-touch infrared synchronization with Axient Digital receivers reduces channel assignment time in multi-channel commercial AV deployments.
• Wireless Workbench 6 Compatible — Centralized RF management platform for spectrum coordination, real-time battery monitoring, remote configuration, and multi-site management.
• Durable Aluminum Housing — Moisture-resistant lightweight construction (340 g / 12 oz without batteries) suitable for regular handling in professional live event and commercial AV workflows.
• TAA-Compliant — Qualifies for federal government procurement under GSA schedules and Trade Agreements Act contract vehicles.

Frequently Asked Questions

What capsules are compatible with the AD2 transmitter body?
The AD2 transmitter body accepts all Shure RPW-series wireless capsules, including the RPW118 (Beta 58A), RPW120 (Beta 87A), RPW122 (Beta 87C), RPW112 (SM58), RPW124 (VP68 omnidirectional), RPW170/RPW174 (KSM8), and RPW184 (KSM9). Capsule swaps are performed in the field without tools by unscrewing the capsule head from the transmitter body.

Is the AD2/B58 compatible with Axient Digital receivers?
Yes. The AD2 is compatible with all Axient Digital receivers including the AD4D (dual-channel) and AD4Q (four-channel). Frequency bands must match: this unit operates in the G57 band (470–616 MHz). It is not compatible with ULX-D, SLX-D, or BLX receivers.

Why choose the Beta 58A capsule over condenser options?
The Beta 58A is a dynamic supercardioid capsule with a frequency response tailored for close-mic vocals (50 Hz–16 kHz), making it the preferred choice for high-SPL live sound reinforcement environments (up to 147 dB) where condensers would be prone to distortion. It provides strong rejection of off-axis sound and feedback without the noise floor sensitivity concerns of condenser capsules in loud environments. For corporate presentations, conferencing, or studio-quality vocal reproduction, consider the Beta 87A or Beta 87C condenser capsules instead.

How many simultaneous AD2 units can operate in the G57 band?
In Standard mode, the Axient Digital system supports up to 47 simultaneous channels per band. High Density mode increases this count for large-scale commercial deployments. Actual channel count depends on the RF environment and antenna infrastructure, and should be coordinated using Wireless Workbench 6.

Is the AD2TA/B58=-G57 TAA-compliant for government purchasing?
Yes. This unit is TAA-compliant and eligible for procurement under GSA schedules and federal contract vehicles requiring Trade Agreements Act compliance.

What warranty does the Shure AD2 carry?
Shure provides a limited 2-year manufacturer warranty on the AD2 handheld transmitter. The Beta 58A capsule is covered separately. Contact Creation Networks for warranty service and support.
