The Soundweb Contrio AC-5S is a simple analog wall controller designed for use with BSS Audio Soundweb London devices. The single-gang US Decora is available in black or white.

The AC-5S is designed to connect to General Purpose Inputs (GPI) (also known as “Control Inputs”) found on Soundweb London devices. Most Soundweb London devices contain 12 GPI. The Soundweb London BLU-GPX contains 36 GPI.

The AC-5S contains a single five-position resistor ladder which is useful for source selection or preset recall. The AC-5S requires one GPI. Therefore, up to 12 AC-5S controllers can connect to a single Soundweb London device, and up to 36 AC-5S controllers can connect to a single BLU-GPX.

The AC-5S is configured using HiQnet Audio Architect via simple drag and drop operations. While almost any parameter can be mapped to the physical controls, the AC-5S is most commonly used for source selection or preset recall.
