The results of Sound Devices' acquisition of Audio Limited, the UK manufacturer and developer of high-performance wireless microphone systems are allowing the Wisconsin-based company to expand its portfolio with a new category of digital wireless solutions for professional production environments with industry-exclusive technologies.
SpectraBand technology is ideal for film and content production crews who travel the world, and won’t need to purchase another receiver dedicated to a specific country or frequency band. SpectraBand gives access to nearly twice the frequencies available with other systems worldwide – almost 2600 available channels. The A20-Mini miniature transmitter will receive a free firmware upgrade to enable SpectraBand.
"As wireless spectrum becomes increasingly crowded, sound professionals need flexibility when it comes to tuning range. 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," says Gary Trenda, RF Applications Engineer at Sound Devices. "We’re excited to offer the A20-RX and an upgrade path for our A10-RX customers."
In the USA, the A20-RX with SpectraBand 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.
Two other notable features of the A20-RX are its front-end filtering and Frequency AutoAssign. While tracking filters are common in wireless receivers, the A20-RX uses superior low-loss, brick-wall SAW filters to deliver excellent performance in noisy RF environments. These built-in filters also provide excellent immunity from nearby IFB or camera hop transmitters without the need for external filters or extra cabling. The AutoAssign feature scans a user-designated tuning band and selects available frequencies for the A20-RX's two channels. This feature is designed to make frequency selection and setting quick and easy.
The new Sound Devices A20-RX digital wireless receiver is compatible with both A20-Mini and A10-TX transmitters. Sound professionals 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 1st. The upgrade program lasts until the end of 2022. The A10-RX may be converted to the A20-RX by sending the unit to Sound Devices for a hardware upgrade.
The release of the A20-RX coincides with supporting firmware for the A20-Mini, A10-TX, 8-Series, SD-Utility and A20-Remote.
The A20-RX is available for purchase worldwide.
