Powered by 100% digital RF modulation and offering adjustable RF power output from 2 to 100mW, the Astral HH delivers ultralong, reliable transmission distance. Built-in RocketAntenna technology eliminates antenna grip dropouts. The Astral HH's high-headroom, ultraquiet preamp boasts an impressive 140 dB dynamic range and a 10 Hz to 20 kHz full audio bandwidth, ensuring the best sound quality possible. Thanks to GainForward architecture, there's no need for gain settings on the microphone—simply adjust trim at the console. The e-Paper display is readable in sunlight, even when the power is off. The button-free design minimizes accidental presses during live performances, with optional control rings available for adding buttons or switches as needed.
With NexLink remote control, AutoAssign for quick frequency scans, customizable body shells to suit any production's aesthetic, along with 10-hour battery life, the Astral HH offers the best of all worlds for the artist, the sound mixer, and the RF tech working concerts, live events, theater, houses of worship, cruises, corporate events, and beyond. It is compatible with the Astral ARX32, ARX16, and ARX8 digital receivers.
- Sound Devices has put all this know-how into its first bespoke microphone capsule, the proprietary CD1—a calibrated dynamic cardioid capsule.
- Its smooth sound is tailored for vocals and is absolutely consistent from unit to unit due to its 100% testing and calibration at the Sound Devices factory.
- The Astral 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 Astral HH Capsule Collar (available separately) over.
- SpectraBand is built into the Astral HH as standard, which results in an astounding tuning range of 470 up to 1525 MHz. This means that no matter where a tour takes you, you can find open frequencies to operate.
- AutoAssign makes scanning and setting frequencies on all transmitters automatic and blindingly fast with one button press.
- You no longer need to stress about talent covering the bottom of the mic, smothering the RF level.
- Sound Devices’ proprietary wideband RocketAntenna means that no matter where the mic is held, the antenna keeps transmitting at the same level. No Dropouts.
- As supplied, the Astral HH microphone has no external controls for talent to accidentally change.
- You can further customize the mic with interchangeable Astral 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.
- The Astral 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? Sound Devices recommends 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.
- As with Astral transmitters, the Astral HH has ultra-long-range NexLink Remote Control built in.
- Change frequencies and even fully power down and up all transmitters at the press of one button from your mixing console.
- Astral wireless, GainForward technology means that there are no gain controls to be set and messed with on the wireless transmitter or receiver.
- Simply adjust gain at the console’s trim with no loss in headroom or noise performance.
Sound Devices’ internal QA lab puts their mics through a battery of brutal tests—dropping, extreme cold, heat, humidity, throwing, soaking, shaking, and vibrating.
- The Astral HH records 32-bit float Broadcast WAV (under 4 GB) or RF64 WAV (over 4 GB) files at 48 kHz sampling rates to a removable microSD card (available separately).
- 32-bit float files are recorded such that gain decisions can be made after recording. Because of the Astral HH's high dynamic range (>140 dB), audio levels are never too high or too low.
- The Astral HH must be set to REC Only Mode. It is not possible to simultaneously record and transmit.
- Worldwide UHF tuning range from 470 to 1525 MHz.
- 10+ hours (10mW) runtime from standard 18650 Li-ion battery
- Proprietary wideband RocketAntenna design not affected when gripping mic at bottom.
- Reversible Capsule Collar—threaded to accept Shure- or Sennheiser-compatible mic capsule, no adapters needed.
- CD1 high-precision, fully calibrated dynamic cardioid mic capsule for mic-to-mic consistency.
- Long-distance NexLink remote control from the Astral ARX32, ARX16, ARX8, and Web App.
- State-of-the-art 100% digital modulation delivers ultra-long transmission distance.
- RF Power output from 2 to 100mW.
- GainForward Architecture—no gain control. Adjust gain at the mixer.
- Full 10 Hz to 20 kHz audio bandwidth.
- High headroom, ultraquiet mic preamp with >140 dB dynamic range.
- Sunlight-readable, e-Paper screen for control and display. Display persists with no batteries
