Meet the half-rack receiver with an entire rack's worth of features. The next-generation Sound Devices A20-Nexus is expandable from 8 channels up to 16 channels with software licenses and features forward-thinking technologies like SpectraBand, the powerful NexLink remote-control link, real time spectrum analysis, and more. With multiple options for audio outputs, powering, and remote control, the Sound Devices A20-Nexus can seamlessly adapt to your workflow, both now and in the future.
SPECTRABAND:
SpectraBand technology delivers a tuning range of 470 to 1525 MHz in a single unit, an industry first. Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band. The included A20-Monarch antennas can receive the entire 470-1525 MHz range, keeping your kit small and tidy.
NEXLINK:
Control your A20-Mini transmitter using the built-in long range remote control link. NexLink's advanced long distance modulation reaches even farther than the A20-Mini's long-range audio transmission.
Features:
- 8-channel ultra-high-performance, true-diversity receivers in a ½ rack size
- expandable to 12or 16-channels via software license (coming soon)
- 470 MHz to 1525 MHz tuning range via SpectraBand Technology
- NexLink: integrated, long distance remote control of all wireless transmitters
- Dante audio-over-IP of RF receiver audio
- flexible powering: via PoE+, DC input, 8-Series, or AC mains (with optional adapter)
- web app control from browser on any computer, smartphone or tablet
- full remote operation capability: power via PoE, audio via Dante, control via web app

- excellent audio quality, full 10 Hz to 20 kHz audio bandwidth
- RF SAW filters for excellent rejection of interference from nearby IFB or camera hop transmitters
- BNC timecode input for auto timecode sync of transmitters over NexLink
Specifications
RF
- 470 to 1525 MHz tuning (1055 MHz switching bandwidth), 25 kHz steps
- SpectraBand Technology for maximum rejection of out-of-band signals
- available frequencies depend on country of operation
- proprietary, 100% digital RF modulation
- standard or long range, selectable per channel
- spurious rejection: >100 dB typical
- cascade antenna output: 50 ohm, wideband power split (pre-LNA), 3 dB insertion loss from front BNC through rear BNC (it is recommended to use an external powered antenna to overcome the 3 dB splitting loss in the Nexus so that the receivers maintain excellent range)
- RF Bias output: 12V, 200 mA each BNC
- Smart antenna support, Wisycom-compatible
Audio
- latency standard modulation = 2 ms, analog or digital outputs
- latency long range modulation = 3.9 ms, analog or digital outputs
- audio frequency response: 10 Hz-20 kHz, +/1 dB relative to 1 kHz
- dynamic range: > 130 dB with A20-Mini as transmitter
- output level: line +20 dBu for 0 dBFS, mic -20 dBu for 0 dBFS
- digital audio output: AES3 balanced connection, 110 ohm output impedance
Powering Sources
- DC Input: dual, redundant
- PoE+: 802.3at, 30W needed (standard 15W PoE 802.3af will not work)
- 8-Series (through unit-to-unit connector when docked)
- AC mains adapter (sold separately)
Powering Levels
- DC input, 10 to 18V in, 2A min
- 11 W idle, default configuration
