BSS EC-4BV-BLK-US Ethernet Controller Volume Control Black

The BSS EC-4BV is a wall-mounted Ethernet controller built for one job: giving room occupants direct, tactile control over Harman HiQnet audio systems without touching a rack or accessing a software interface. It occupies a US Decora single-gang wall box and connects via a single Ethernet cable that carries both data and PoE power — a wiring efficiency that makes it a natural fit for commercial AV installations where running separate power to every control point adds cost and conduit. The push/rotary encoder handles continuous parameter control, primarily volume, while the four configurable buttons address discrete functions including preset recall and source selection, all defined in HiQnet Audio Architect during commissioning.

The multi-color backlit LCD provides clear visual feedback at the control point — users can confirm the active preset or current level without any knowledge of the underlying system architecture. The black US Decora finish integrates naturally into standard commercial and corporate interior environments. For systems integrators working in the Harman ecosystem, the EC-4BV represents a mature, well-supported control layer: it's been deployed across boardrooms, auditoriums, and education spaces where the requirement is straightforward — give a non-technical user reliable volume and preset control, and make it look like it belongs on the wall.
