The A20-RX Audio Devices It is a dual channel, true versatility receiver that uses SpectraBand technology. SpectraBand gives the A20-RX Receiver and A20-Mini Transmitter an extremely wide tuning range from 470MHz – 1525MHz.
A20-RX is the successor to A10-RX.
With the wireless spectrum becoming increasingly crowded, audio professionals need flexibility when it comes to tuning the range. The A20-RX is the first receiver on the market that can tune into not only the common UHF TV bands around 470-608MHz, but much higher than that.
SpectraBand eliminates the need to purchase different wireless receivers dedicated to specific frequency bands. In the USA, the A20-RX can be tuned to the 600MHz Guard band (614-616MHz), duplex print gap 600MHz (653-663MHz), ISM band 900MHz (902-928MHz), 900MHz band (941.5MHz) MHz (-960 MHz), and with the appropriate license, the 1.5 GHz AFTRCC band (1435-1525 MHz). This is in addition to the base USA UHF TV band of 470-608MHz which is commonly available. In general, this total is about 285 MHz of available spectrum.
In the UK, the A20-RX can set the duplex transmission gap of 800MHz (823-832MHz), the shielding band is 800MHz (863-865MHz), and with the appropriate license, the DME and 1.5GHz bands (961-1015MHz, 1045-1075MHz, 1105-1154MHz, 1518-1525MHz). This is in addition to the commonly available UK UHF TV baseband of 470-702MHz. In general, this total is about 383MHz.
The A20-RX is the second product in the first wireless audio hardware line. The first product, the A20-Mini transmitter, also receives a free firmware upgrade to enable SpectraBand when used with the A20-RX. The A20-RX is also compatible with all tuning ranges of the full-size A10-TX and is SuperSlot compatible with the SL-2 SuperSlot Wireless Module and 8-Series Synthesizer Recorder.
The A20-RX also features a high-discrimination front-facing filter for better performance in noisy RF environments and automatic frequency mapping for a faster setup.
While tracer filters are common in radio receivers, the A20-RX uses ultra-high-quality, low-loss SAW filters and brick walls to deliver excellent performance in noisy radio frequency environments. These built-in filters also provide excellent immunity to nearby IFBs or camera hop transmitters without the need for external filters or additional cables. AutoAssign scans the user-set tuning range and selects the available frequencies for the A20-RX channels. This feature is designed to make frequency identification and setting quick and easy.
What does it correspond to?
A20-RX compatible with both A20 mini And the A10-TX transmitters. Audio professionals with a previous A10-RX model can upgrade their receivers to the A20-RX for $995 or a discounted price of $750 if they purchased the A10-RX within the past 12 months or the A20-Mini since June 1.
A10-RX can be converted to A20-RX by sending the unit to audio devices for hardware upgrade. Customers can start the upgrade process by visiting service.sounddevices.com/contact-support.
The upgrade program runs until the end of 2022. I like when companies provide an upgrade path for their products because it shows they care about their customers and the investment they’ve made.
The A20-RX version synchronizes with the firmware supporting the A20-Mini, A10-TX, 8-Series, SD-Utility and A20-Remote. To download the supporting firmware, visit www.sounddevices.com/download
