The A20-RX from Sound Devices is a dual-channel digital receiver designed for use with the A10-TX and A20-Mini transmitters and featuring a powerful feature set that ensures professional-level reliability, even in noisy RF environments.
SpectraBand technology gives the A20-RX a massive tuning range from 470 to 1525 MHz, allowing for worldwide use, while Advanced Digital True Diversity topology uses two completely independent RF receivers for each channel, providing a total of four receiver circuits for clean reception with fewer dropouts. The system is completely digital, ensuring pristine quality audio and providing extremely long transmission distances with brick-wall SAW filters to eliminate out-of-band interference. The unit`s AutoAssign function automatically scans a tuning band and selects clean, interference-free frequencies for you, saving you valuable time on set.
A separately available A-XLR, A-TA3, or A-SL adapter is required to use the A20-RX.
At a Glance
- SpectraBand technology: compatible with the A20-Mini from 470 to 1525 MHz and all tuning ranges of the A10-TX
- Advanced Digital True Diversity topology uses two complete RF receivers for each of the two channels, with four RF receivers in total
- 100% digital long-range modulation delivers the extremely long transmission distances
- GainForward Architecture compatible with the A20-Mini: set the Mini`s gain levels via trim control (with an 8-Series) or at the A20-RX (for other mixers)
- Full 10 Hz to 20 kHz audio bandwidth
- Excellent immunity from nearby IFB or camera hop transmitters without the need for external filters or extra cabling
- Analog line-level or AES digital audio output
- A backplate is not included; users can choose between the A-XLR, A-TA3, or A-SL adapters
