The Allen & Heath AB168 is a compact yet robust remote audio rack designed specifically for use with the GLD and Qu series digital mixing consoles. This portable stage box integrates 16 XLR inputs and 8 XLR outputs, providing a flexible and efficient solution for live sound reinforcement, recording, and event production. Constructed with a rugged steel chassis and reinforced connectors, the unit withstands the rigors of touring and frequent setup changes. Its lightweight form factor makes it easy to transport and place on stage or in a rack, while the integration with dedicated control protocols ensures seamless communication with compatible consoles. At the core of the AB168 is its reliable digital audio transmission capability. The stage box connects to the mixer via a single Cat5e or higher cable using Allen & Heath’s proprietary dSNAKE protocol, which delivers low-latency, high-fidelity audio over distances up to 120 meters. Each XLR input features professional-grade preamps with ample headroom and low noise floor, suitable for microphones and line-level sources alike. The eight outputs provide balanced analog signals for monitors, front-of-house systems, or auxiliary sends. The unit’s internal power supply is designed for stable operation under varying voltage conditions, reducing the risk of performance interruptions during critical events. The build quality of the AB168 emphasizes long-term durability. The front panel is equipped with status indicators for power, link, and signal presence, allowing quick visual checks during setup. The I/O panel is recessed and protected to minimize damage from cable strain or accidental impact.

Additionally, the rack ears are reinforced for secure mounting, and the chassis includes ventilation slots to prevent overheating. This attention to material selection and assembly contributes to consistent performance across numerous shows and installations. Versatility is another hallmark of this device. It functions as a remote stage box, enabling the mixer to be placed at front-of-house while the rack remains near the stage, reducing cable runs and clutter. The AB168 also supports multiple box configurations, allowing expansion of input and output counts by daisy-chaining additional units via the link port. Compatibility with both GLD and Qu series mixers means it can serve different workflow preferences without requiring alternative hardware. The user experience is further enhanced by plug-and-play operation—once connected, the console automatically detects and maps the box’s channels, saving setup time. Given its performance and construction, the AB168 offers substantial value for professionals and semi-professionals seeking a reliable digital snake solution. The price point reflects a balance between premium features and budget-conscious production needs, making it an accessible option for houses of worship, small touring acts, rental houses, and educational institutions. Careful engineering ensures that signal integrity remains consistent even with multiple units cascaded, and the absence of complex configuration procedures lowers the learning curve for new users. In summary, the Allen & Heath AB168 delivers dependable audio connectivity and robust hardware in a portable form, suited to a wide range of live and recorded applications.
