Sound Devices A20-HH Control 1 - Control Ring

Flexible Mic Control with a Single Button Interface
The Sound Devices A20-HH Control 1 adds a new level of tactile flexibility to the A20-HH handheld digital microphone by giving users a single programmable button and a multicolor LED status light. Whether you're managing a busy live stage, working on set, or running broadcast audio, this control ring allows quick access to essential functions while keeping your hands on the mic and your focus on performance.

Programmable Commands for Live or Broadcast Use
The A20-HH Control 1 is designed for maximum compatibility with the A20-HH’s flexible command system. Using the A20-HH Settings menu, users can assign a wide range of functions to the single button, including RF power toggle, mute, record start/stop, or even macros that trigger external systems via Astral-series receivers. This makes it ideal for broadcast crews, theater performers, or live sound engineers who need fast, simple mic control.

Visual Feedback with Multicolor LED Monitoring
In addition to the single button, the Control 1 ring features a built-in multicolor LED that can be programmed to indicate battery level, mute status, RF strength, or other custom alerts. This allows users and engineers to verify system status with a quick glance, even in fast-paced or dimly lit environments.

Part of a Fully Interchangeable Control System
The Control 1 ring is part of a complete modular design from Sound Devices. It fits into the A20-HH system alongside the Control 0 (no button), Control 3 (three-button), and Control Switch (side toggle) rings. All options are designed for easy installation and removal, giving you the freedom to tailor your microphone to suit each event, talent, or production workflow.

Ideal for Hands-On Applications in Any Venue
This single-button design hits the sweet spot for many users—offering physical control without the clutter or complexity of multiple inputs. Perfect for FOH engineers or talent who want to mute the mic between takes or switch transmission modes without remote access, the Control 1 puts the essentials at your fingertips.

Fully Integrated with NexLink Remote Workflow
Even with a physical control button, the A20-HH remains fully controllable through Sound Devices' NexLink wireless protocol. The Control 1 complements this system by adding redundancy and allowing quick, local interaction with the mic—especially useful if remote access is unavailable or undesired during a show.
