Sound Devices A20-HH Control Kit

Bundle of Control Rings for A20-HH Microphones
The Sound Devices A20-HH Control Kit is a convenient multi-pack of interchangeable control rings for the A20-HH handheld wireless microphone. Designed for professionals who need flexibility and redundancy on live productions, this kit includes 12 total control rings—4 each of the Control 1, Control 3, and Control Switch models—giving your team instant access to multiple interface options for different users or performance needs.

Preconfigured for Fast Swapping and Customization
Each control ring in the bundle installs quickly onto the A20-HH without tools, enabling users to change microphone control layouts in just minutes. Whether you're outfitting microphones for a variety of roles or need to respond to last-minute changes in the field, having multiple ring types on hand saves time and ensures you’re always ready.

Three Button Configurations for Versatile Use
The kit includes four Control 1 rings, which feature a single programmable button with an LED indicator; four Control 3 rings, each with three individually programmable buttons with status LEDs; and four Control Switch rings, offering a side-mounted latching switch and multisegment LED bar. Each ring supports customizable commands such as mute, RF on/off, power, record, or talkback through the A20-HH Settings menu.

Ideal for Touring, Broadcast, and Theater Applications
Whether you're supporting a touring band, managing a live television broadcast, or coordinating a multi-mic stage production, this control ring bundle ensures that your wireless handheld microphones are always optimized for the task. The included rings offer tactile functionality for on-the-fly changes, cue triggering, or even communication via auxiliary audio routing.

Fully Compatible with NexLink and Astral Systems
All control rings in the kit integrate seamlessly with the A20-HH’s NexLink remote control capabilities and are fully supported by Sound Devices Astral-series receivers, including the A20-SuperNexus and A20-Nexus Go. The rings allow for physical control while still enabling remote configuration via NexLink or the A20-Remote app.

Simplify Inventory Management with a Complete Kit
Rather than ordering control rings individually, the A20-HH Control Kit lets rental houses, production companies, and technical teams keep consistent stock in one purchase. It’s also a practical choice for organizations that manage large mic fleets across multiple departments, venues, or touring crews.
