The BSS Audio AC-5S is a simple and cost-effective analog wall controller designed for seamless integration with BSS Audio Soundweb London devices. Built for reliable and intuitive operation, the AC-5S features a five-position resistor ladder, making it ideal for source selection or preset recall in commercial audio installations.

The AC-5S connects directly to a General Purpose Input (GPI), also known as a Control Input, on compatible Soundweb London devices. Most Soundweb London devices provide 12 GPIs, allowing up to 12 AC-5S controllers to be connected to a single unit. When used with the Soundweb London BLU-GPX, which includes 36 GPIs, up to 36 AC-5S controllers can be supported, offering flexible multi-zone control options.

Configuration is completed using HiQnet Audio Architect software through simple drag-and-drop functionality. While a wide range of system parameters can be mapped to the controller, the AC-5S is most commonly used for switching between sources or recalling preset configurations. Available in black or white finishes and offered in single-gang US Decora or single-gang EU form factors, the AC-5S delivers a clean, professional appearance suited for retail, corporate, hospitality, and educational environments.
