BSS Soundweb Contrio EC-4B Ethernet Controller – White

BSS Soundweb Contrio EC-4B Ethernet wall controller, white (EU)

The Soundweb Contrio EC-4B is an Ethernet wall controller for use within Harman HiQnet systems. It can control and monitor parameters within BSS Audio Soundweb London and other HiQnet-enabled devices, including Crown DCi series amplifiers, making it a flexible front-of-room control point for a wide range of installed sound applications.

The EC-4B is configured through simple drag-and-drop operations within the HiQnet Audio Architect software application, allowing parameters such as volume, source selection, and preset recall to be mapped to the controller’s 4 buttons. This lets integrators tailor the exact function of every control to match the needs of the room it serves.

The controller includes 1 LCD screen alongside its control surface, which is multi-color backlit and capable of eight different colors with adjustable intensity. This allows the display to show custom text labels or reflect a binary parameter state, such as red and green for muted and unmuted status, giving users immediate visual feedback.

The EC-4B is available in white finish and connects via a single Ethernet port that supplies configuration, control, monitoring, and Power over Ethernet in one cable, simplifying installation in both new-build and retrofit projects. It is available in single-gang US Decora or EU mounting formats, and its low-noise electronics are designed for reliable long-term use in professional AV environments.
