Visit Sound Devices at stand 8.C95 at the IBC tradeshow, September 15th-18th in Amsterdam, to get hands-on demos of the latest additions to the Astral family – A20-Nexus Go and A20-TX. The newly introduced A20-TX digital wireless bodypack transmitter has a multipurpose input, flexible powering, and ultra-low-power e-Paper display.

The A20-TX transmitter and A20-Nexus Go receiver will join other Astral-family products in the Sound Devices booth, including the A20-Nexus multichannel, true diversity wireless receiver with SpectraBand, NexLink RTSA, and Power-over-Ethernet and audio via Dante; the svelte A20-Mini bodypack transmitter with GainForward and SpectraBand; and the A20-RX 2-channel slot-in portable true-diversity wireless receiver.  

We will also display our 8-Series line, which includes Scorpio, 888, and 833 mixer-recorders. Designed specifically for sound professionals’ workflows, each 8-Series mixer-recorder has unprecedented recording power and a rugged, efficient interface.   

We plan to celebrate our 25th anniversary in a special way at IBC this year. In addition to demoing our MixPre II Series audio mixers, with crystal-clear, ultra-low-noise Kashmir preamps, 32-bit float bit depth and a 192 kHz sample rate, we’ll have an opportunity for a stand visitor to win a limited-edition silver MixPre-3 II mixer-recorder.

Join us to learn about the new A20-Nexus Go and A20-TX! 

Are you curious to learn about the newest additions to our Astral family of wireless gear? On August 3rd, at 10:00am CDT (3:00pm GMT), Sound Devices will host a live-streaming event online where Director of Product Design and Management Paul Isaacs and RF Applications Engineer Gary Trenda will demonstrate the new A20-Nexus Go multichannel true-diversity wireless receiver and A20-TX digital wireless transmitter. Following the demonstration, you’ll have the opportunity to ask Paul and Gary questions for them to answer live. 

With 4 receiver channels that can be expanded to 6 and 8 with software expansion licenses and a form factor compact enough for a bag or a half-unit space on a sound cart, the A20-Nexus Go receiver is ready for any application. It has SpectraBand’s 169-1525 MHz global tuning range, the ability to set gain at the receiver and not the transmitter with GainForward, long-range remote control of transmitters via NexLink, integrated RTSA (Real Time Spectrum Analyzer), and more. 

The A20-TX transmitter is compatible with the widest array of input sources, from lavs and dynamic mics, to phantom-powered condenser mics, balanced line-level sources, and even AES digital mics. It accepts AA batteries of any chemistry, and offers a battery life up to 12 hours. The A20-TX transmitter includes the first full, true balanced ultra-low-noise high-headroom mic preamp, and has Astral-family features, like NexLink, SpectraBand, and GainForward.
