BSS EC-4B-WHT – Soundweb Contrio Ethernet Wall Controller, 4 Buttons (White)

Product Overview

The BSS EC-4B-WHT is a white Soundweb Contrio Ethernet wall controller designed for Harman HiQnet commercial AV systems. This single-gang PoE wall controller integrates directly with BSS Audio Soundweb London processors, Crown DCi series amplifiers, and any HiQnet-compatible device, providing end-users with intuitive hands-on control of audio parameters from a standard wall position. Configured entirely within HiQnet Audio Architect via drag-and-drop, the EC-4B-WHT simplifies commissioning for commercial AV installations of any scale.

Product Description

The BSS EC-4B-WHT is a commercial-grade Ethernet wall controller that brings precise parameter control to any room served by a Soundweb London or HiQnet-based DSP system. The white finish matches standard US Decora single-gang wall plates, making it an ideal choice for bright office environments, conference rooms, corporate lobbies, and educational spaces where white fixtures are the norm. The controller features four programmable buttons and one 64×128 pixel LCD screen — both multi-color backlit with eight selectable colors and adjustable intensity — giving system designers full flexibility over visual feedback and button labeling. Each button can be assigned to binary parameter control such as mute, preset recall, or source selection, enabling straightforward user interfaces without complex programming. Power is delivered via PoE (Power over Ethernet) on a single Cat5e/Cat6 cable that also carries configuration data, control commands, and monitoring traffic — eliminating the need for a local power supply. The EC-4B-WHT connects to any BSS Audio Soundweb London chassis or HiQnet device on the network, including Crown DCi series amplifiers, and can monitor and adjust parameters in real time. A configurable sleep function turns off all LEDs after a defined idle period, useful in dimly lit environments such as auditoriums or house of worship spaces. Security is addressed via remote lock/unlock through external control systems, with local unlock supported via a four-digit PIN entered on the buttons. All configuration is performed in HiQnet Audio Architect using drag-and-drop — no scripting required. The EC-4B-WHT is the white US Decora version; a black variant (EC-4B-BLK) and EU form factor versions are also available through Creation Networks.
