PreSonus NSB 16.8 - Network Stage Box

The PreSonus NSB 16.8 is a high-performance network stage box designed for professional live sound and installed audio applications. It provides 16 remote-controllable XMAX Class A preamplifiers and 8 analog outputs, all accessible via a single AVB Ethernet cable. Built with rugged steel construction and a 2U rackmount form factor, the NSB 16.8 integrates seamlessly with PreSonus StudioLive Series III mixers and UC Surface control software, offering ultra-low latency and pristine audio quality up to 96 kHz.

Advantages

With the NSB 16.8, you can place your audio I/O exactly where you need it—on stage, in a machine room, or at a remote location—while maintaining full control from the mixing position. The remote-controllable preamps eliminate the need for a separate snake, reducing setup time and cable clutter. Individual +48V phantom power and a gain range of 0 to +60 dB provide flexibility for any microphone or line-level source. The locking Ethercon and combo connectors ensure reliable connections in demanding environments.

Suitable for

• Live sound reinforcement for concerts, theaters, and houses of worship
