BSS EC-4BV-WHT - Ethernet Controller with 4 Buttons and Volume Control. White

The BSS EC-4BV-WHT is an Ethernet wall controller from the Soundweb Contrio family for HARMAN HiQnet ecosystems. From its single Ethernet port with PoE, it allows you to configure, control and monitor parameters of the BSS Soundweb London and other HiQnet devices such as the Crown DCi , with quick commissioning using HiQnet Audio Architect via drag-and-drop . This white version is offered in a single-gang US Decora or EU format, for clean integration into all types of projects.

Its interface combines a push-button rotary encoder , a multi-color LED ring , four backlit buttons and a 64x128 px LCD display . The ring can act as a VU meter , display the volume level while turning and signal binary states when pressed (e.g. mute). The backlight supports 8 colors with adjustable brightness to code zones or functions. The panel incorporates Sleep mode (dims/turns off LEDs after inactivity), remote lock/unlock , local unlocking by 4-digit PIN and a Locate button to identify the equipment from the software.
