Sound Devices Astral HH Digital Wireless Handheld Microphone
Astral HH Digital Wireless Handheld Microphone.
The Astral HH is one of the most advanced and best-sounding handheld microphones available today. Designed for professional touring, live events, theatre, houses of worship and corporate stages, it offers unmatched tuning flexibility, fast setup, and exceptional durability. It can access more usable spectrum than any other handheld mic, making it easy to find clean frequencies wherever your work takes you. Its body components can be customised to match any aesthetic, making it ideal for tours, productions, and branded events.
Outstanding Performance
Engineered to deliver exceptional audio quality, the Astral HH uses fully digital RF modulation and offers one of the longest RF ranges in the industry. With full 10 Hz–20 kHz audio bandwidth and up to 10 hours of battery life, it ensures consistent, high-quality performance. All of this comes in a beautifully designed yet highly rugged chassis built for life on the road.
Global Touring Made Simple
With SpectraBand™ included as standard, the Astral HH boasts an extraordinary tuning range from 470 MHz to 1525 MHz. No matter the venue or country, you can reliably find open frequencies. And with AutoAssign, scanning and assigning frequencies across your system is almost instant — just one button press.
Compatible With Any Capsule
The Astral HH works natively with mic capsules from any major manufacturer. Both Shure-style and Sennheiser-style thread types are built in — no adapters required. Simply flip the Capsule Collar to switch thread standards.
Add Controls When You Need Them
The Astral HH ships clean, with no external buttons for performers to accidentally press. If you need more control, optional Astral HH Control Rings allow you to add configurable buttons or switches, including options for triggering console macros and other workflows.
Customisable Design
The Body Shell, Control Ring, Capsule Collar and CD1 can all be swapped out in minutes, giving you full creative control over the microphone’s look. They can be painted, wrapped, decorated or fully customised. For premium finishes, Rebel Trading Company (UK) provides bespoke painting and crystal designs, perfect for tours, branded shows or standout performers.
RocketAntenna – Reliable RF, No Dropouts
Talent gripping the microphone too low is no longer a concern. The Astral HH’s patent-pending RocketAntenna ensures consistent RF transmission no matter where the mic is held, helping to eliminate signal dropouts.
Built-In Long-Range Remote Control
Every Astral transmitter includes NexLink® long-distance remote control. From the mixing console, you can change frequencies, adjust settings, and even fully power transmitters on or off with a single command.
Built to Survive the Road
Constructed with a magnesium die-cast frame, stainless steel components, and an impact-resistant polycarbonate shell, the Astral HH is built for the toughest touring environments. Sound Devices tests every unit to extreme standards — drops, temperature cycles, humidity, vibration and more — ensuring long-term reliability.
