Overview

The Behringer S32 solves the cable management problem that plagues mid-to-large live rigs: how do you get 32 mic-level signals from stage to front of house without running an analog multicore that adds weight, cost, and failure points? The answer is AES50 — a single Cat5e cable carrying all 32 inputs and 16 outputs bidirectionally with sub-millisecond latency courtesy of Klark Teknik's SuperMAC implementation. The 32 onboard Midas-designed preamps are remote-controllable from the host console, meaning gain rides, phantom power toggling, and preamp adjustments happen from the engineer's position — no walkie-talkie required.

In the studio or broadcast context, the S32 functions as a high-channel-count I/O expander for any AES50-equipped interface or console. The Midas preamp topology offers a noise floor and harmonic character that handles dynamic range gracefully — transients from drums and percussive sources come through cleanly, and quiet sources like room mics or light acoustic instruments maintain low self-noise at moderate gain settings. Build quality is rack-standard 1U steel chassis with solid XLR connectivity. The S32 belongs in any X32 or M32 ecosystem where stage-to-FOH channel count demands a dedicated, professional-grade stage box rather than a patchwork of direct boxes and splitters.

Pros & Cons

👍 Pros

  • 32 remote-controllable Midas preamps give front-of-house engineers gain staging control from the console without sending a stagehand to the rack.
  • AES50 with Klark Teknik SuperMAC carries all 32 channels bidirectionally on a single Cat5e cable, replacing an entire analog multicore snake.
  • 16 output channels provide ample return paths for complex monitor mixes or multi-amp stage setups.
  • Sub-millisecond latency over AES50 keeps the digital signal chain transparent — indistinguishable from analog in live mixing practice.
  • 1U rack-mountable form factor integrates cleanly into a standard stage rack without consuming excessive space.

👎 Cons

  • The S32 is not a standalone device — it requires an AES50-equipped console (X32, M32, or compatible), making it a significant ecosystem commitment.
  • 16 outputs may be limiting for large festival rigs with extensive monitor systems requiring more than 16 discrete returns.
  • No onboard preamp metering or local display — gain staging is fully dependent on the remote console, which can complicate troubleshooting when the console is 30+ meters away.
  • At 12.32 pounds in a 1U chassis, the S32 is dense — rack positioning and ventilation need consideration for mobile rigs.
  • Phantom power is applied per-bank rather than per-channel on some firmware versions, which can be a workflow issue when mixing condenser and dynamic mics on the same bank.

Frequently Asked Questions

AES50 is a point-to-point digital audio networking protocol that carries up to 48 channels of 96kHz audio bidirectionally over a single Cat5e cable. Klark Teknik's SuperMAC implementation on the S32 keeps latency below 0.1ms per hop — in practice, this means you're routing 32 mic-level inputs from stage to FOH with no perceptible delay and no analog multicore snake to run.
They're Midas-designed preamps manufactured by Behringer under the Midas brand — the same circuit topology used in the M32 console family. They offer remote gain control, phantom power switching, and the characteristic warmth and headroom associated with Midas designs at a significant cost reduction versus standalone Midas hardware.
The S32 requires an AES50-equipped host — it's designed to pair with the Behringer X32, Midas M32 family, or any mixer with AES50 I/O. It functions as a stage box, not an independent mixer, so a compatible console or digital snake system is required.
The S32 provides 16 outputs, which can be used for monitor wedges, in-ear transmitters, amplifier feeds, or any stage-level returns from the console's bus outputs.
A single shielded Cat5e (or better) cable handles all 32 inputs, 16 outputs, and remote control data over AES50. Cable runs up to 100 meters are supported, which covers most stage-to-FOH distances.
