Tour Globally, Find Open Frequencies

SpectraBand™ is built into the A20-HH as standard, which results in an astounding tuning range of 470 MHz up to 1525 MHz. This means that no matter where a tour takes you, you can find open frequencies to operate. And AutoAssign makes scanning and setting frequencies on all transmitters automatic and blindingly fast with one button press. 

 Introducing the CD1 Mic Capsule 

Sound Devices has long been known for impeccable audio quality. It has put all this know-how into its first bespoke microphone capsule, the patent-pending CD1 – the only calibrated dynamic capsule in the world. Its smooth sound is tailored for vocals and is absolutely repeatable from unit to unit due to its 100% testing and calibration at the Sound Devices factory. 

 … or use any Other Capsule 

The A20-HH microphone can natively use any manufacturer’s mic capsule, whether conforming to the Shure- or Sennheiser-style threads – with no adapter. Both threads are built-in; to change from one thread to another, simply flip the A20-HH Capsule Collar over. 

 Easily add Controls 

The A20-HH microphone as supplied has no external switches for talent to accidentally change. You can further customize it with interchangeable A20-HH Control Rings to add physical control buttons or switches. These controls can be menu-configured for many different options, including triggering macros on mixing consoles. 

 Make it Your Own

The A20-HH has a quick-change Body Shell, Control Ring, Capsule Collar, and CD1 that you can decorate, paint, and bedazzle to fit the style of any costume. In just minutes, change the entire look of the microphone by swapping out these pieces. Want even more of a wow factor? We recommend Rebel Trading Company, a UK-based company that specializes in microphone customization. They offer custom paint finishes and crystal customization, even incorporating designs, artwork, names, and logos.

 RocketAntenna: No Dropouts

You no longer need to stress about talent covering the bottom of the mic, smothering the RF level. Sound Devices’ patent-pending wideband RocketAntenna means that no matter where the mic is held, the antenna keeps transmitting at the same level. No Dropouts.

 Full Remote Control, Built-in 

All Astral transmitters have ultra long-range Remote Control built-in as standard – a protocol called NexLink®. Change frequencies and even fully power down and up all transmitters at the press of one button from your mixing console. 

 Adjust Gain at the Console, not on the Wireless 

With Astral wireless, GainForward™ technology means that there are no gain controls to be set and messed with on the wireless transmitter or receiver – saving you valuable time. Simply adjust gain at the console’s trim with no loss in headroom or noise performance.
