BSS EC-4BV-WHT-US Ethernet 4-Button Volume Controller

The BSS EC-4BV is an Ethernet-connected wall controller purpose-built for Harman's HiQnet ecosystem, giving installers a clean, professional interface for end-user control of Soundweb London audio systems. At its core, the unit offers a push/rotary encoder, four programmable buttons, and a backlit LCD screen — all mapped to system parameters through HiQnet Audio Architect's drag-and-drop interface. In practice, this means a conference room user gets a simple wall plate with a volume knob and clearly labeled buttons for mute, source select, or preset recall, while the integrator retains full control over what each element does behind the scenes. The multi-color backlighting across buttons, encoder ring, and display provides immediate visual status — you can tell at a glance whether a room is muted, which zone is active, or if a system fault has been flagged.

Installation is straightforward: the US Decora form factor drops into standard wall openings, and the single Ethernet port handles everything — PoE power, bidirectional control data, and system monitoring. No local power supply, no separate control wiring, no additional converters. The build quality is consistent with BSS's professional install products, with a solid-feeling encoder and buttons that hold up under daily use in corporate, education, and house-of-worship environments. Configuration changes happen in software, not at the wall, which means reassigning controls for a room reconfiguration is a laptop session rather than a truck roll. For integrators working within the Soundweb London platform, the EC-4BV is a refined, dependable end-point controller that keeps the user experience simple while preserving full system flexibility underneath.
