Sound Devices announced that it is shipping the A20-RX, a new two-channel, true-diversity wireless receiver with proprietary SpectraBand technology, that, in tandem with the A20-Mini transmitter, is stated to deliver a tuning range of 470 MHz – 1525 MHz.
The A20-RX also offers high-discrimination front end filtering designed to provide better performance in noisy RF environments as well as Frequency AutoAssign for faster setup. The receiver is compatible with both A20-Mini and A10-TX transmitters.
Users with the previous model, A10-RX, can upgrade the hardware of their receivers to the A20-RX for $995 USD or for a reduced price of $750 if they purchased their A10-RX within the last 12 months or an A20-Mini since June 1. The upgrade program lasts until the end of 2022.
“As wireless spectrum becomes increasingly crowded, sound professionals need flexibility when it comes to tuning range,” says Gary Trenda, RF applications engineer at Sound Devices. “The A20-RX is the first receiver on the market that can tune not only in common UHF TV bands around 470 – 608 MHz, but far above that. We’re excited to offer the A20-RX and an upgrade path for our A10-RX customers.”
SpectraBand is designed to eliminate the need for purchasing different wireless receivers dedicated to specific frequency bands. In the USA, the A20-RX can tune to the 600 MHz guard band (614-616 MHz), 600 MHz duplex gap (653-663 MHz), 900 MHz ISM Band (902-928MHz), 900 MHz STL Band (941.5-960 MHz), and, with the appropriate license, the 1.5 GHz AFTRCC band (1435-1525 MHz). This is in addition to the core USA UHF TV band from 470-608 MHz that’s commonly available. Overall, this totals approximately 285 MHz of available spectrum.
In the UK, the A20-RX can tune to the 800 MHz duplex gap (823-832 MHz), 800 MHz guard band (863-865 MHz), and, with a proper license, the DME and 1.5 GHz bands (961-1015 MHz, 1045-1075 MHz, 1105-1154 MHz, 1518-1525 MHz). This is in addition to the core UK UHF TV band from 470-702 MHz that’s commonly available. Overall, this totals approximately 383 MHz.
The A20-RX is the second product in Sound Devices’ first wireless product line. The first product, the A20-Mini transmitter, is receiving 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 an SL-2 SuperSlot wireless module and 8-Series mixer-recorder.
The release of the A20-RX coincides with supporting firmware for the A20-Mini, A10-TX, 8-Series, SD-Utility and A20-Remote. Go here for more specifics on the A20-RX, and here to download supporting firmware.
