Sound Devices A20-HH Control Ring 3 - Command Ring for Astral HH (LED / 3 Buttons)

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

The interchangeable Astral HH Control Ring comes in five models: A20-HH Control Blank with no external physical controls; 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; and 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 Astral HH Settings menu, such as on/off, mute, none, record, power, RF on/off, etc.

Among the assignable commands is Aux audio routing, which can be used to activate talkback mode. The command can instruct a Sound Devices Astral® receiver to reroute audio to a different output. That means an onstage musician can push a button and request the monitor engineer make a change, or a sports broadcaster can slide the control switch and automatically communicate with a producer located remotely in a broadcast truck – all without lag time or needing a separate, expensive microphone.
