PreSonus NSB32.16 AVB Networked Stage Box

The PreSonus NSB32.16 is a networked stage box built around 32 remote-controllable XMAX Class A preamps, delivering the clean, headroom-rich gain staging that these preamps are known for across every input simultaneously. The signal path from mic capsule to AVB network stream stays transparent — you hear the source and the room, not the preamp. With 64x16 AVB channel capacity (32 direct input channels plus 32 gain-compensated channels over 16 output returns), the NSB32.16 replaces a heavy multi-pair analog snake with a single Ethernet cable while adding the gain compensation layer that makes shared-console workflows practical. Every input and output uses locking connectors — combo XLR/TRS on the inputs, standard XLR on the 16 outputs, and etherCON-style locking Ethernet on the AVB ports — because connections that come loose during a live show are not acceptable.

This stage box is purpose-built for mid-to-large format live sound productions running PreSonus StudioLive Series III consoles, where a front-of-house engineer and a monitor engineer need independent control of shared inputs without compromise. The remote preamp control through UC Surface or the mixer itself means gain adjustments happen from the mix position, not at the stage box — a workflow improvement that pays dividends on every show. The rugged 3U rack enclosure with multi-position rack ears accommodates various mounting orientations, and at 10.2 pounds it is light enough for single-person handling. The Mute All button on the front panel provides a physical safety net for those moments when you need every channel silent immediately. For productions that have committed to the PreSonus AVB ecosystem, the NSB32.16 is the signal chain foundation that makes the rest of the system sing.
