A Proven Standard in the Allen & Heath Ecosystem
Designed for Allen & Heath digital consoles from the "Qu", "GLD", and "SQ" series, the AB168 naturally integrates into live and installation setups. It unlocks the full potential of compact surfaces like the "Qu-PAC" or "Qu-SB" and the "SQ" series by providing I/O close to the stage, while remaining simple to cable and operate.
Who Is It For and What Are Its Uses?
Ideal for rental companies, houses of worship, multipurpose venues, clubs, and tours, the AB168 suits both mobile setups and fixed installations. Positioned on stage or mounted in a rack with the optional kit, it speeds up soundchecks, reduces analog cable lengths, and ensures reliable audio flows.
