Description

Overview

The A20-Nexus is a half-rack wideband true diversity receiver with remote control and real time spectrum analysis, It ships with eight channels and is expandable via software license.

Delivery includes A20-Nexus, (2) A20-Monarch SpectraBand antennas with articulated arm mounting clamps and cables, and (2) 2.4 GHz antennas for remote control with mounting brackets and cables.

SpectraBand
SpectraBand technology delivers a tuning range of 470 – 1525 MHz in a single unit to allow you to 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 2.4 GHz long range remote control link. NexLink’s advanced long distance modulation reaches even farther than the A20-Mini’s long-range audio transmission.

Network Options
Configure your A20-Nexus for Dante audio, use the built-in web server to control the receiver using the web browser on any computer, tablet, or phone, and even power the A20-Nexus remotely using Power-over-Ethernet (PoE).

Real Time Spectrum Analysis
Instantly visualize the fluctuating RF spectrum around you in real time – while running all channels of the audio.

GainForward
With the A20-Mini’s GainForward Architecture, easily set the Mini’s gain, low-cut, and limiter directly on your A20-Nexus or 8-series recorder.

Flexible Form Factor
Thanks to its half-rack size, the A20-Nexus is equally at home in a rack, in a bag, or docked to an 8-Series recorder with the A20-QuickDock (sold separately) for a cableless kit.

Long Range Transmission
The state-of-the-art, 100% digital long-range modulation offers the same great audio quality (10 Hz – 20 kHz) as Sound Devices' standard modulation scheme with a longer range for both line-of-sight and heavy multipath transmission.
