Allen & Heath AB-168 Portable AudioRack 16 x 8 Audio Interface Stage Box

Portable Remote I/O For Professional Digital Mixing Systems

The Allen & Heath AB-168 is a compact, rugged portable AudioRack designed to bring high-quality microphone inputs and line-level outputs closer to the stage or performance area. Built for use with Allen & Heath GLD and Qu digital mixing systems, the AB-168 functions as a remote stage box that reduces cable runs, improves signal integrity, and streamlines live sound and installed audio workflows.

Sixteen Mic Preamps And Eight Balanced Outputs In One Unit

This portable AudioRack provides sixteen XLR mic/line inputs powered by Allen & Heath’s high-performance microphone preamps, each with individual phantom power control and LED indicators. Eight balanced XLR line outputs support flexible routing for monitors, front-of-house feeds, or distributed audio zones, making the AB-168 suitable for concerts, houses of worship, theaters, and corporate AV systems.

Single-Cable Connectivity With dSNAKE Protocol

Using Allen & Heath’s dSNAKE protocol over standard Cat5 cabling, the AB-168 connects to compatible mixers with a single cable run of up to 393 feet. This long-distance digital connection allows inputs and outputs to be positioned exactly where needed without sacrificing audio quality or system reliability, while locking EtherCon connectors ensure secure connections in demanding environments.

Expandable Design For Larger Audio Systems

An onboard expander port allows the AB-168 to be daisy-chained with additional AudioRacks or connected to Allen & Heath ME personal monitoring systems. This modular approach supports scalable system growth, making it easy to adapt the same equipment for small gigs, touring productions, or fixed installations with evolving requirements.

Built For The Realities Of Live Sound And Touring

Designed for durability, the AB-168 features a tough metal chassis with integrated rubber bumpers that protect the unit when placed horizontally or vertically on stage floors. A built-in carry handle and lightweight construction make it easy to transport, while optional rackmount hardware allows the unit to be installed in standard equipment racks when needed.

Seamless Integration And Automatic System Updates

When connected to compatible Allen & Heath mixers, the AB-168 automatically synchronizes firmware, ensuring consistent operation and compatibility across the system. This plug-and-play behavior minimizes setup time and reduces technical complexity, allowing engineers to focus on sound quality rather than system management.
