PreSonus NSB32.16 Stage Box

The PreSonus NSB32.16 scales the AVB stage box to thirty-two preamps and sixteen returns, feeding StudioLive Series III consoles and R-series rack mixers over one network run. It is the full-band snake replacement for AVB rigs, with recallable gains and mix-engineer-friendly monitoring workflows. Stacks with NSB16.8 units for even larger stages.

01 · What it does—and what that changes in your rig.

Product overview

Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.

The payoff

Stage Box decisions, organized around the whole rig.

The NSB32.16 is PreSonus's full-size answer to the analog snake: thirty-two recallable mic preamps on stage, sixteen analog returns for wedges or fills, and a single EtherCon run carrying up to 48 channels of AVB audio back to wherever your StudioLive Series III console or R-series rack mixer lives. It is the piece that lets you pull every XLR off the floor, replace the copper snake with a Cat6 run, and still hand the monitor engineer a full complement of outputs without adding a second box. For AVB-based rigs, this is the snake head.

Function

How it works in the path

At forty watts typical draw from a standard IEC inlet, it is not a heavy power burden, but the fifty-five-watt ceiling means you should account for the headroom in a conditioned strip rather than guess. The 3U steel chassis weighs in at four kilograms and sits at 250mm deep — shallow enough to fit a road-standard rack without fighting the back panel. In practice, the single network port is both the strength and the constraint: one cable for 48 channels is clean and fast at load-in, but AVB means you are committed to AVB-capable switches and PreSonus AVB infrastructure. Recallable preamp gains mean your line check can start from a known-good file rather than from zero every night, which matters on a fast changeover.

Best fit

Where it earns its place in the rack

This box belongs in a touring or install rig that is already built around StudioLive Series III or is being built around it from the ground up. If your console is a Series III and your stage needs more than sixteen inputs, the NSB32.16 is the natural next step before you start daisy-chaining smaller boxes. Who should look elsewhere: anyone running a different console ecosystem — the AVB implementation here is designed to play inside the PreSonus world, and coaxing it into a non-PreSonus AVB network is more engineering project than production tool. If your input count is under sixteen, the NSB16.8 is a lighter lift.

In the rack

Details worth deciding before load-in.

  • Use a managed gigabit switch certified for AVB — consumer switches and unmanaged switches will not pass AVB streams correctly, and the fault won't be obvious until you're chasing phantom signal loss during soundcheck.
  • Map your sixteen analog outputs deliberately before the first show: returns 1-8 for monitor mixes, 9-12 for in-ear personal mixers, and 13-16 as utility sends keeps the stage patch consistent night to night and gives your monitor engineer a predictable starting point.
  • If you need more than 32 inputs, the NSB32.16 can stack with an NSB16.8 on the same AVB network — plan your switch port count and network topology before the first load-in, not during it.
  • Secure the EtherCon run at both the box and the switch with a secondary strain-relief tie; a pulled network connector mid-show takes down every channel simultaneously, and EtherCon alone is not immune to a hard yank across a busy stage.

Compatibility

Treat connector names as the start of the check—not the answer. These are the boundaries that determine a complete working path.

Best fit · Stage Box

Use it when 3U and 250 mm of depth fit the case.

Plan the companion path

Complete the path with upstream and downstream gear that matches connector, direction, signal type, protocol, and wiring standard.
