Customize your control. Sound Devices has made it easy to not only set commands on the A20-HH microphone remotely via NexLink, but also change the physical controls on the mic, simply by swapping out the A20-HH Control Ring, giving you maximum flexibility for your applications.

The interchangeable A20-HH Control Ring comes in four models:

• A20-HH Control 0 with no external physical controls but a multicolor status/audio level LED
• A20-HH Control 1 with one button and multicolor LED
• A20-HH Control 3 with three buttons, each with multicolor status LED
• A20-HH Control Switch with a latching side switch and a six-segment multicolor LED bar

Each ring has a different set of available commands that can be configured in the A20-HH Settings menu, such as on/off, mute, none, record, power, RF on/off, etc.
