Shure ADX2FD/SM58 Axient Digital Wireless Handheld Microphone Transmitter

Expand your sound system and add professional polish to your wireless audio with the ADX2FD/SM58. The ADX2FD handheld transmitter equips you to transmit an RF signal on two discrete carriers. Compatible with Axient® Digital Wireless Systems, the ADX2FD comes with the renowned SM58 microphone capsule, making this a great choice for capturing vocals. Its integrated Diversity ShowLink remote control function enables real-time settings adjustments and automatic interference avoidance.

Choose between three transmission modes: Standard Mode optimizes wireless coverage, while High Density Mode intensifies the coverage and maxes out the system’s channel count, and 50mW High Power Mode lets you drive increased power on a single frequency. Other features include wide tuning up to 184 MHz and secure transmission via its encryption enabling.

Moisture-resistant and durable, the ADX2FD metal build helps it endure the wear and tear of demanding applications—all while remaining lightweight and easy to use.
