PreSonus NSB 8.8 AVB-Networked Stage Box Bundle

The PreSonus NSB 8.8 is a networked stagebox that fundamentally changes how gain is managed in a live sound rig. Rather than running a long analog snake from stage to FOH — with all the noise floor and signal degradation that entails — the NSB 8.8 places eight XMAX Class A preamps at the source, converts the audio to AVB over a single Ethernet run, and hands gain control to the engineer at the desk. The XMAX preamps are the same high-headroom, low-noise design found in PreSonus's StudioLive consoles: transparent at moderate gain, musical under drive, and quiet enough that a ribbon mic on a whispered vocal won't surface the noise floor. The 16x8 AVB channel architecture carries eight direct input signals and eight gain-compensated copies simultaneously — the FOH engineer and monitor engineer each receive the same source at independent levels, and the gain compensation system ensures that a 3dB FOH gain change doesn't blow out the wedge mix.

Physically, the NSB 8.8 is engineered for the realities of touring. The enclosure is robust, the handles are real, and every XLR — both audio and Ethernet — uses a locking mechanism that doesn't release from a cable snag or a kick from a performer who didn't watch where they stepped. The included rackmount kit integrates the unit into a standard 19-inch rack for permanent installations or rack case touring rigs. Pairing the NSB 8.8 with a StudioLive Series III console and UC Surface running on a tablet creates a genuinely wireless gain-management workflow: walk the stage during line check, trim preamps from the tablet, and never ask a monitor tech to relay level adjustments again. For engineers locked into the PreSonus ecosystem, this unit delivers a meaningful operational upgrade over passive or analog-only stagebox solutions.
