Behringer SD16 Stage Box

The Behringer SD16 is a budget-friendly 16-input, 8-output AES50 stage box compatible with Behringer X32 and Midas M32 consoles. Daisy-chains to additional SD16s for larger channel counts. The default pickup when a budget X32 / M32R rig needs more inputs at the stage.

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 SD16 is the native stage box for the X32 and M32 family — it sits on or near the stage, collects up to 16 mic-level sources, sends them back to the console over a single EtherCon cable via AES50, and returns 8 line-level outputs to feed wedges, IEM transmitters, or amp racks. It occupies 3U in a rack and draws a modest 55 watts nominal. If you're already committed to the X32 or M32 ecosystem, this is the expected answer to getting inputs off the stage and down the snake without running 16 individual analog lines.

Function

How it works in the path

The two AES50 ports are the most important thing on the back panel. Port A is your primary link to the console; Port B is labeled redundant, which means you can daisy-chain a second SD16 and double your stage-side capacity to 32 inputs and 16 outputs without touching the console configuration — the M32 and X32 see both boxes natively. At 6 kg and 320 mm deep, it fits a shallow road rack without drama. The 8 XLR line outputs are real-world enough for most monitor rigs: four IEM transmitters plus a couple of wedge sends covers a typical small-to-mid production.

Best fit

Where it earns its place in the rack

Pick the SD16 if your console is an X32, M32, or M32R and your budget is the primary constraint — at $509, nothing purpose-built in this category competes on price within the ecosystem. Where it gives ground is outside that ecosystem: AES50 is not Dante, not MADI, not Milan, so if your console speaks anything else, this box sits out entirely. Engineers on touring rigs that may hot-swap consoles mid-run, or who need dante network integration, should look at a more protocol-flexible stage box and treat the cost delta as an insurance premium.

In the rack

Details worth deciding before load-in.

  • When daisy-chaining a second SD16 via AES50 B, physically label both boxes and their cables at load-in — 'SD16-A / AES50 to console' and 'SD16-B / AES50 to SD16-A' — so the next engineer doesn't spend twenty minutes tracing a silent chain during soundcheck.
  • The 8 line outputs return from the console's output bus assignments, not automatically from inputs — confirm your X32/M32 routing template maps the correct buses to SD16 outputs before doors, or your IEM mixes will be silent at the wrong moment.
  • Power this box from the same distro as your console if possible; AES50 can tolerate cable runs up to 100 meters, but clock stability benefits from both ends of the link sharing a common ground reference.
  • At 320 mm depth, the SD16 fits most standard shallow stage racks, but verify your rack's internal depth before the gig — some DJ-style cases run closer to 280 mm and will leave the IEC inlet hanging off the rear rail.

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 149 mm of depth fit the case.
