The Allen & Heath M-SQ-SLINK adds a second intelligent SLink port to any compatible SQ digital mixing console, dramatically expanding system flexibility and I/O capacity.

Designed for live sound, touring, broadcast, houses of worship, and installed AV systems, the M-SQ-SLINK provides up to 128 inputs and 128 outputs of digital audio with full preamp control at 48kHz or 96kHz operation.

Expand Your SQ System

With the same functionality as the built-in SLink port, the M-SQ-SLINK allows an SQ mixer to connect to an additional 128x128 channels of digital audio.

This enables:

• Larger stage I/O configurations

• FOH and monitor splits

• Broadcast and recording feeds

• Expanded personal monitoring systems

• Multi-console integration

The card runs independently from the console’s built-in SLink port, allowing two different Allen & Heath protocols to operate simultaneously in one system.

Multi-Protocol Connectivity

The M-SQ-SLINK supports intelligent switching between multiple Allen & Heath audio transport protocols:

• gigaACE (96kHz)

• DX (96kHz)

• dSnake (48kHz)

With independent sample rate conversion (SRC), the card allows two different protocols to be used at the same time — expanding compatibility across product families.

This means an SQ console can simultaneously integrate:

• ME personal monitoring systems

• DX expanders

• dSnake stage boxes

• Qu, SQ, or dLive systems

Ultra-Low Latency Performance

Engineered for professional live applications, the M-SQ-SLINK delivers:

• Ultra-low 52µs transport latency

• Automatic firmware matching

• Intelligent mode switching

• Plug-and-play installation

• Network bridge capability for Layer 3 tunneling

• VLAN and managed switch compatibility

Connections are supported up to 100 meters over Cat5e/Cat6 cabling.
