Overview

The BSS EC-4B-BLK-US is a wall-mounted Ethernet controller purpose-built for managing audio parameters within Harman's HiQnet networked audio ecosystem. It features four fully programmable buttons and a 64x128 pixel LCD screen with multi-color backlighting, giving end users an intuitive, at-the-wall interface for tasks like adjusting volume, selecting sources, or muting zones. The black US Decora form factor fits standard single-gang electrical boxes, allowing the controller to blend seamlessly into conference rooms, classrooms, houses of worship, and other installed sound environments.

A key advantage of the EC-4B is its Power over Ethernet design—a single Cat5e or Cat6 cable delivers both network connectivity and power, eliminating the need for a local electrical outlet and simplifying installation. All programming and parameter assignments are handled through Harman's HiQnet Audio Architect software, giving system designers precise control over what each button does and what the LCD displays. For facilities already invested in Harman BSS, Crown, or dbx networked audio, the EC-4B provides an elegant and dependable control surface that keeps day-to-day audio management accessible to non-technical users.
