Sound Devices A20-Nexus

A20-Nexus 8TX view

Sound Devices A20-Nexus is here !


A half rack size receiver unit capable of receiving 8 channels (with upgrade option to receiving 12 or 16ch. through software licenses). A Multi Channel Receiver, yes of course, but so much more. Like a full bandwidth spectrum analyzer which lets you see what is going on on your location before you even have started your recording day. The Nexus real time spectrum analyzer will tell you what frequencies to use and you only have to say yes ! and the Nexus will change its channels on the receiver and via the NexLink it will set your A20 transmitters remotely as well... and all this live without waiting for a complete frequency scan. 


Sound Devices Nexus AnalyzerThe analyzer shows you well beyond the wide full switching bandwidth of 1055MHz to get a really good idea where you are. The 2.4GHz communication channel NexLink lets you not just set your frequencies, but you can change all of your transmitters settings from a great distance. Even when your transmitter is yet too far away to receive any audio, your Nexus will be able to see and communicate with your transmitter through this NexLink. 

The approved SpectraBand technology will reject any garbage from out-of-band signals, securing a robust reception of your own transmitters.

With its perfect audio (10-20kHz ! and a dynamic range >130dB !) you will not notice anymore that you are virtually cable free. The audio outputs can be found on a sub-D connector providing Mic or Line or AES digital outputs, whatever you prefer. But there is also a Dante in/output so you will need only this one very fast connecting cable to send all of your channels to your recorder. So you have a bunch of 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). 

Sound Devices A20-Monarch antennaThe A20-Nexus comes standard with a pair of A20-Monarch butterfly antenna's to optimize reception on your sound cart or sound bag. These antennae can receive the entire 470-1525MHz range en still keeping your bag or sound cart tidy.
