EC-4BV

Ethernet Controller with 4 Buttons and Volume Control

SRP from £375.00 + VAT


The Soundweb Contrio EC-4BV is an Ethernet wall controller for use in Harman HiQnet systems. The EC-4BV can control and monitor parameters within BSS Audio Soundweb London and other HiQnet devices, including Crown DCi series amplifiers.
The EC-4BV is available in black or white, and in single-gang US Decora or single-gang EU form factor. The EC-4BV contains a single Ethernet port for configuration, control, monitoring, and power via PoE. The EC-4BV is configured via simple drag-and-drop operations within the software application HiQnet Audio Architect.


The EC-4BV contains one push/rotary encoder, one encoder ring, four buttons, and one LCD screen. The buttons, encoder ring, and LCD screen are multicolour backlit, capable of eight different colours with adjustable intensity.


The push/rotary encoder can be rotated for continuous parameter control (e.g. volume). The push/rotary encoder can also be pressed for binary parameter control (e.g. mute) or preset recall.
The encoder ring can display a bouncing audio meter. When the push/rotary encoder is rotated, the encoder ring can temporarily display a volume setting. When the push/rotary encoder is pressed, the encoder ring can temporarily display a binary parameter setting (e.g. red/green for muted/unmuted status).


The four buttons can be pressed for binary parameter control (e.g. mute), preset recall, or source selection.


The LCD screen has a screen resolution of 64x128 pixels, and can display custom text and graphics.


The EC-4BV supports ‘sleep’ functionality. After a specified amount of time with no user input, the EC-4BV can turn off all LEDs. This is useful to avoid distraction in a dimly lit environment. Any user interaction will ‘wake up’ the controller.


The EC-4BV can be remotely locked and unlocked via other control systems. The EC-4BV can be locally unlocked via a four-digit PIN entry on the buttons.


The EC-4BV supports multiple modes of operation. This allows the push/rotary encoder and encoder ring to be reassigned dynamically to different parameters based on which buttons are selected.
