BEHRINGER SC-U StageConnect Interface

Three audio networks, one small converter.

Your X18 or XR18 sends Ultranet. Your WING console and P24 monitoring system use StageConnect. Your computer talks USB. SC-U is a three-way converter between them, and it adapts its internal routing to the connections you make.

A stage box and personal monitors for WING

Use an X18, XR18 or MR18 mixer as a stage box with a WING console. SC-U converts 16 channels from Ultranet to StageConnect. Asynchronous sample rate conversion keeps the clocks on both consoles separate. In the other direction, the P16 monitoring system works with WING, and both setups can run together.

Add a computer to the network

The USB-C port carries up to 32 channels in four in/out configurations: 32/0, 24/8, 16/16 or 8/24. In many setups the configuration is fixed. Play 16 channels from a computer to a P16 monitoring system or a Turbosound iQ speaker system. Or connect an additional computer to WING without using its USB Type-B connector. It works with Windows 10 and 11, OSX and Linux.

Power from the chain, long cable runs

Depending on the host, SC-U can take remote power over StageConnect. Otherwise use the included 12 V DC adapter. Ultranet reaches up to 75 metres on shielded CAT5e, and StageConnect up to 40 metres on 110 Ω DMX cable. Latency is 0.1 ms.

Features

• Three-way converter: converts between Ultranet, StageConnect and USB, and passes MIDI between USB and StageConnect
• Automatic routing: internal routing adapts to the active connections; every connection except Ultranet Out affects it
• 32 channels over USB-C: the USB Type-C connector carries up to 32 channels in both directions between SC-U and a computer
• Four USB configurations: AUDIO IN/OUT cycles 32/0, 24/8, 16/16 and 8/24 in/out, though in many setups the configuration is fixed
• Computer support: USB audio class 2 compatible with Windows 10 and 11 (ASIO/WDM), OSX (CoreAudio) and Linux
• Ultranet in and out: two RJ45 ports carry 16 channels in both directions, up to 75 metres on shielded CAT5e
• StageConnect Host and Client: XLR male and female ports each transmit up to 32 channels, up to 40 metres on shielded balanced 110 Ω DMX cable
• Ultranet to StageConnect: converts 16 channels, so an X18, XR18 or MR18 mixer can serve as a stage box with a WING console
• Separate clocks: asynchronous sample rate conversion keeps the clocks on both consoles separate
• P16 with WING: StageConnect to Ultranet conversion lets the P16 monitoring system work with WING
• Computer to Ultranet: with ULTRANET IN active, USB runs 16 in and 16 out, playing 16 channels to a P16 system or Turbosound iQ speakers
• Extra computer for WING: connects an additional computer to WING without using the USB Type-B connector on WING
• Computer to P24: the computer's USB output can feed a P24 monitoring system, with SC-U as the StageConnect Host
• Low latency: 0.1 ms I/O latency on a 32-channel, 44.1/48 kHz, 24-bit StageConnect bus
• Power options: 12 V DC / 2.5 A, 30 W adapter included, with remote power input via SC Client and output via SC Host
• StageConnect status LED: red shows disconnected, green a stable connection and yellow occasional transmission errors
• Compact: 118 x 63 x 112 mm, 0.71 kg and 2 W power consumption
