Note on RF Interference
Sound Devices does not guarantee the absence of any interfering spurs across all bands in all situations. Some small spurs can
originate within the Nexus, and others can come from many sources (Ethernet, AES/EBU interconnects, external mixer/recorders,
USB drives, USB keyboards, etc.). This, combined with the extreme sensitivity of the Nexus's front end, mean that the user has to
be very careful with the quality of cables used, as well as antenna and antenna cable routing and placement.
We highly recommend placing antennas as far as possible from other pieces of equipment, especially antennas from intentional
transmitters such as IFB units.
Sound Devices recommends using high-quality, shielded Ethernet cables (whether using PoE+ or not) to minimize interference at
RF frequencies caused by Ethernet. Additionally, it is a best practice to keep Ethernet cables as far away from the receiving
antennas and the receiving antennas' coax cable (if used).
Servicing the A20-Nexus
Do not attempt to service the A20-Nexus. The internal parts are microscopic and not user serviceable. Please send to Sound
