Why engineers choose Sound Devices Astral

Sound Devices builds in Reedsburg, Wisconsin, and made its name on recorders and mixers for film and television production, where a failed take is expensive and a failed recording is unforgivable. Astral applies that standard to wireless, and it is now on the RF packages of tours including The Weeknd, Lorde and Chappell Roan.

Three things set it apart in practice. SpectraBand gives a 169 to 1525 MHz tuning range, so one system follows the show across regions with different spectrum rules. GainForward removes transmitter gain staging altogether, which takes an entire category of mistake out of a busy changeover. And NexLink gives long-distance remote control of transmitters, including group power on and off, so nobody has to chase a performer backstage to change a setting.

Receivers also expand by software licence rather than replacement. Buy the frame for the channel count you need now, add channels when the show grows.

The range at 7HERTZ

  • Astral ARX8: compact four-channel receiver built for bag work, expandable to six or eight channels by licence. Integrated real-time spectrum analysis and AutoAssign frequency coordination.
  • Astral ARX16: eight channels in a half-rack frame, expandable to twelve or sixteen, with Dante and web-based control. The usual hub of a larger Astral system.
  • Astral ARX32: sixteen to thirty-two channels for large-format productions, with the Astral Opto expansion adding native Optocore I/O.
  • Astral TX and Mini Plus: bodypack transmitters. The TX takes lavaliers, mics and line sources, while the Mini Plus is built for concealment on talent, with longer battery life and IP67 water resistance.
  • Astral HH: handheld transmitter, with Control Rings available as an accessory.
  • Astral Guitar Box: DI interface for instrument channels on the same system.

Buying Sound Devices in the UAE and GCC

RF coordination in dense urban environments is its own discipline, and the Gulf has plenty of congested spectrum. As official distributor we supply Astral systems with manufacturer warranty and regional technical support, and we would rather help with frequency planning at design stage than at load-in.

Frequently asked questions

How much does an Astral wireless system cost?
It depends on channel count, how many transmitters you need and which licences you want enabled. Send us your channel requirement and we will quote the full system.
How many channels does each Astral receiver handle?
The ARX8 runs four channels and expands to six or eight. The ARX16 runs eight and expands to twelve or sixteen. The ARX32 runs sixteen and expands to twenty-four or thirty-two. Expansion is by software licence, so you buy the frame once and add channels as the show grows.
What is GainForward and why does it matter?
GainForward removes the need to set gain on the transmitter. That takes a whole category of error out of a fast changeover, and it means a pack handed to a performer is already right.
Will Astral work across different countries and spectrum rules?
The Astral receivers, the TX and the Mini Plus tune from 169 to 1525 MHz, and the HH from 470 to 1525 MHz. That wide SpectraBand range is why touring productions use the system across regions. For a specific territory, contact us and we will confirm what is legal to operate there.
Do you help with frequency coordination?
Yes. RF planning in congested urban spectrum is part of what we do as distributor. The receivers include real-time spectrum analysis and AutoAssign, but for a large or difficult site, bring us in at design stage, not on the day.
Does Astral support Dante?
Yes, on the ARX16 and above. The ARX32 can also take the Astral Opto expansion for native Optocore I/O. Tell us your network and we will confirm the right configuration.
What is the difference between Astral TX and Mini Plus?
Both are bodypacks. The TX is the standard pack with a multipurpose input for lavaliers, mics and line sources. The Mini Plus is built for concealment where size matters most, with longer battery life and IP67 water resistance, which is worth having for outdoor work in this climate.
Can Astral be used for live music as well as film production?
Yes. It was built for location sound but the channel density and RF performance have made it standard on major tours. Contact us with your application and channel count.
What warranty and support do I get?
Full manufacturer warranty with regional technical support from our Dubai team, as official distributor for the Middle East and Gulf.
