Allen & Heath SQ SLink Audio Interface Module for SQ Series Mixers

Allen & Heath SQ SLink Audio Networking Interface Card

The Allen & Heath SQ SLink is a professional digital audio networking module designed for SQ series digital mixers. The card expands the connectivity capabilities of an SQ mixer by providing an additional independent SLink connection, enabling seamless integration with a wide range of Allen & Heath digital audio systems including dSnake, DX expanders, GigaAce devices, and ME personal monitoring systems.

Supporting up to 128×128 channels of bidirectional audio and control data, the SQ SLink card significantly enhances system flexibility for live sound, installations, broadcast applications, and large-scale audio deployments. Unlike a simple extension, the module duplicates the mixer’s internal SLink functionality while operating independently, allowing users to run two different Allen & Heath networking protocols simultaneously. This capability enables complex system configurations and expanded routing possibilities without compromising performance.

The card supports both 96kHz and 48kHz operation, ensuring compatibility with a broad range of Allen & Heath equipment operating at different sample rates. This flexibility makes it ideal for integrating multiple audio ecosystems within a single workflow while maintaining high-quality audio transmission and reliable network communication.

The SQ SLink module provides an efficient solution for expanding stage I/O, connecting personal monitoring systems, implementing digital splits, and extending networked audio infrastructure. Its single locking EtherCon connector ensures secure and dependable network connections in demanding professional environments where reliability is critical.

Designed specifically for SQ mixers, the SQ SLink card offers a scalable and versatile networking solution that increases connectivity, system expansion options, and routing capacity. Whether used for touring productions, installed sound systems, or professional monitoring applications, the SQ SLink delivers powerful audio networking performance and seamless integration across Allen & Heath platforms.
