Shure ADX2/SM58 – Axient Digital Handheld Transmitter with SM58 Capsule

Product Overview

The Shure ADX2/SM58 is a professional Axient Digital handheld wireless transmitter pairing the ADX2’s ShowLink remote control platform with the legendary SM58 dynamic cardioid capsule — an industry-standard choice for live vocal reinforcement and commercial AV deployments. Designed for sound reinforcement integrators and AV system operators, it delivers AES-256 encrypted digital audio across a 146 MHz tuning range with 2-ms latency, and operates in G57 (470–616 MHz), K54 (606–663 MHz), and X55 (941–960 MHz) frequency bands.

Product Description

The ADX2/SM58 combines the RF performance and remote management features of the Axient Digital ADX2 platform with the familiarity and reliability of the SM58 capsule, trusted across houses of worship, touring productions, auditoriums, and multi-purpose rooms worldwide. ShowLink enables the FOH operator to remotely adjust gain, RF power, and mute status in real time without accessing the transmitter, which is critical in large-venue deployments where performers are on stage. The SM58’s cardioid polar pattern provides effective rejection of off-axis sound and stage bleed, reducing feedback risk in high-SPL environments. The transmitter runs up to 9 hours on the included SB920 rechargeable lithium-ion battery, with external charging contacts supporting multi-bay networked charging via Shure’s SBC840 or SBC220. For a compatible Axient Digital receiver, see the Shure AD4DNP Two-Channel Digital Wireless Receiver. For a higher-SPL condenser capsule option on the same ADX2 body, consider the Shure ADX2/K9N.

Key Features

• SM58 Dynamic Cardioid Capsule — The industry-standard capsule for vocal reinforcement delivers brightened midrange and bass roll-off for warm, clear reproduction with proven feedback rejection in live AV environments.
• ShowLink Remote Control — Allows real-time, wireless adjustment of gain, RF output, mute, and other parameters from front-of-house using the AD610 access point and Wireless Workbench 6 software.
• AES-256 Encryption — Provides secure digital audio transmission for corporate, government, and sensitive commercial AV installations.
• 146 MHz Tuning Range — Wide UHF tuning within the G57 band allows system designers to coordinate large channel counts and avoid interference in congested spectrum environments.
• Selectable RF Output (2/10/40 mW) — Allows integrators to balance transmission range against channel density, supporting up to 100 m (328 ft) line of sight.
• 9 Hours Battery Life — Included SB920 rechargeable lithium-ion battery provides up to 9 hours of runtime at 10 mW, with precision time-remaining metering in hours and minutes.
• IR Sync — One-touch infrared receiver sync accelerates multi-channel system setup and frequency coordination during installation and event changeovers.
• Automatic Gain Adjustment — Reduces manual level-setting time for AV operators managing multiple transmitters across a complex installed wireless system.
• Interchangeable Capsule Design — Swap the SM58 for any compatible Shure wireless capsule (KSM9, KSM8, Beta 58A, Beta 87A, Beta 87C, and others) to adapt the transmitter to different applications without replacing the body.
• High-Density Mode — Supports maximum simultaneous channel counts in spectrum-limited venues, operating alongside standard coverage mode for flexible system design.
• Backlit LCD — Displays frequency, group/channel, mute/lock status, RF output level, and remaining battery life for at-a-glance system monitoring during live events.
• Lightweight Aluminum Housing — Durable, moisture-resistant construction at 338 g (11.9 oz) without battery, suited for continuous use in commercial AV installations and touring productions.

Typical Applications

• House of worship main-stage vocal reinforcement with multi-channel Axient Digital wireless systems
• Auditorium and performing arts venue productions requiring remote transmitter management via ShowLink
• All-hands room and corporate event AV systems with high ambient SPL environments
• Multi-purpose room and training room installations where the SM58’s familiarity reduces operator training time
• Broadcast studio and live-event production requiring AES-256 secure wireless audio transmission

Frequently Asked Questions

Why choose the SM58 capsule on the ADX2 body over a standalone SM58 wireless system?
The ADX2/SM58 places the SM58 capsule on Shure’s flagship Axient Digital wireless platform, adding ShowLink remote control, AES-256 encryption, wide 146 MHz tuning, high-density mode, and compatibility with Axient Digital receivers — features not available on entry-level wireless systems. This makes it the appropriate choice for professional installations where RF management and remote transmitter control are operational requirements.

Which Axient Digital receivers work with the ADX2/SM58?
The ADX2/SM58 is compatible with all Axient Digital series receivers, including the AD4D (two-channel) and AD4Q (four-channel). Match frequency bands (G57, K54, or X55) when configuring a system.

How does ShowLink work with the ADX2/SM58?
ShowLink requires an AD610 access point connected to the same network as Shure Wireless Workbench 6 (WWB6). Once configured, the operator can remotely adjust gain, RF output, mute, and frequency on the ADX2/SM58 in real time from the FOH position.

Can the SM58 capsule be replaced with a condenser capsule?
Yes. The interchangeable capsule design allows field replacement with compatible Shure wireless capsules including the KSM9, KSM8, Beta 87A, Beta 87C, and others. No tools are required — simply unscrew the SM58 and thread on the replacement capsule.

What is the warranty on the ADX2/SM58?
Shure provides a limited 2-year manufacturer warranty. Contact Creation Networks for warranty support and AV system design consultation.
