Behringer SC88 StageConnect Interface — 8 Inputs, 8 Outputs on One Cable

The Behringer SC88 is a 1U StageConnect interface that turns a single XLR cable into a complete analog I/O node for live rigs, studios, and hybrid setups. Eight combo XLR/TRS inputs feed through onboard TRIAD microphone preamps, while eight balanced XLR line outputs return audio through high-performance ESS DAC conversion. This interface keeps both directions of signal flow on the same StageConnect line, with remote power riding alongside audio and MIDI on one cable and two Ultranet outputs for personal monitoring.

What Makes the SC88 Stand Out

The TRIAD preamp design delivers clean capture with high common-mode rejection and fine 0.5 dB analog gain steps, giving engineers repeatable trim control across all eight inputs. ESS DAC conversion on the output side keeps the analog return path quiet, while the StageConnect protocol sends 32 channels of uncompressed 24-bit / 48 kHz audio bidirectionally over a single 110-ohm XLR cable — this unit simply claims its 8-in / 8-out slice of that pipe.

Eight TRIAD Preamps with Remote Gain Control

The eight front-end channels are designed to be controlled from a distance. Each input accepts mic or line level on a combo jack, with switchable 48 V phantom power per channel for condenser microphones and active DIs.

• Input Channels: 8 combo XLR/TRS — accepts microphones and line-level sources on the same jack
• TRIAD Microphone Preamps — eight channels with high common-mode rejection and stable performance across a wide range of source impedances
• Phantom Power: 48 V, individually switchable — engage per channel for condensers and active DIs without affecting the rest
• Gain Steps: 0.5 dB analog increments — fine trim resolution for repeatable gain staging

Eight Line Outputs with ESS DAC Conversion

The output stage mirrors the input count, returning eight balanced line-level feeds for monitors, in-ear transmitters, or outboard gear. ESS DAC conversion keeps the analog return path quiet and accurate, while the XLR-M connectors lock in securely on stage.

• Output Channels: 8 balanced XLR line outputs — feed floor wedges, IEM transmitters, or rack gear
• ESS DAC Conversion — clean conversion from the StageConnect digital stream back to analog
• Total Channel Count: 16 (8 in / 8 out) — fits within the 32-channel StageConnect bandwidth budget

StageConnect, MIDI, and Remote Power on a Single Cable

StageConnect ties this interface into the wider Behringer, Midas, and Klark Teknik ecosystem. Audio, MIDI, and remote power all travel down the same XLR line, replacing what would otherwise be a bundle of analog snakes.

• StageConnect Ports: 2 (Master and Slave) — daisy-chain additional StageConnect devices
• Ultranet Outputs: 2 — feed P16 / P24 personal monitoring systems
• Remote Power: 12 V DC / 18 W over StageConnect — powers the unit from a host console without a local PSU
• USB: Type-B — connects to the desktop control panel for remote gain and preamp settings
• MIDI Pass-Through — transmits and receives MIDI commands to other Behringer StageConnect products
• Form Factor: 1U rackmount, 483 x 169 x 49 mm, 2.2 kg — fits a standard 19" rack and travels light

Engineers, Bands, and Houses of Worship Running StageConnect Rigs

The Behringer SC88 is the right choice for live engineers and touring bands who need to expand analog I/O on a Behringer Wing, Midas, or Klark Teknik console without running a multi-channel analog snake. Bands already using a Wing Compact or Wing Rack can add eight mic preamps and eight returns over a single XLR, freeing up stage cable runs. Houses of worship and small-to-mid venues benefit from the same single-cable architecture, especially when paired with P16 or P24 personal monitoring systems through the Ultranet ports. Studio producers bridging a StageConnect console to outboard gear will appreciate the MIDI pass-through and the desktop control panel over USB.

StageConnect — A Behringer, Midas, and Klark Teknik Ecosystem

StageConnect debuted alongside the Behringer Wing as a digital protocol that sends 32 channels of uncompressed 24-bit / 48 kHz audio bidirectionally over a single 110-ohm XLR cable, with power and MIDI riding on the same line. The unit sits inside this ecosystem as a compact analog I/O node, designed to interoperate with StageConnect devices from Midas and Klark Teknik as well as the wider Behringer catalog.
