PreSonus NSB-8.8 NSB 8.8 8x8 AVB Stagebox

The NSB 8.8 is a networked digital stagebox that routes 8 inputs and 8 outputs to PreSonus StudioLive Series III mixing systems over AVB Ethernet. It eliminates the need for heavy analog snakes by transferring clean, multi-channel digital audio over a single Cat5e/Cat6 cable.

It features 8 locking combo mic/line inputs with remote-controlled XMAX Class-A preamps, alongside 8 locking XLR analog line outputs. The combo jacks accept both standard balanced XLR microphone cables and 1/4-inch line-level connections.

Onboard DSP provides automatic gain compensation for shared streams across an AVB network. While the master console sets the physical analog preamp gain, secondary mixers can adjust their local digital trim levels independently without disrupting the main front-of-house mix.

Yes, the unit includes an integrated 2-port AVB switch equipped with locking etherCON jacks. This allows you to easily link multiple NSB-series stageboxes in a series or connect network control devices without needing an external AVB switch.

All preamp settings—including gain levels and +48V phantom power—are adjusted digitally from a StudioLive Series III console or remotely via PreSonus Universal Control software. There are no physical gain knobs on the stagebox itself to prevent accidental tweaking on stage.

Yes, while it is housed in a rugged floor-ready chassis with protective side handles, it can be rackmounted using an optional 19-inch rackmount ear kit. It is also designed to be compatible with standard Ace Backstage floor stage pockets for permanent installations.

The physical Mute All button quickly mutes all 8 analog inputs at the stagebox level. This gives stage technicians a fast, safe way to hot-swap microphones and instruments without generating loud pops or needing access to the mixing console.

No, the NSB 8.8 uses PreSonus's AVB network protocol and is designed exclusively for ecosystem compatibility with PreSonus StudioLive Series III consoles, rack mixers, and software.
