The BSS Soundweb Contrio EC-4BV is a feature-rich Ethernet wall controller designed for intuitive control and monitoring of Harman HiQnet audio systems. It provides advanced user interaction with BSS Audio Soundweb London, Crown DCi Series amplifiers, and other HiQnet-enabled devices.

Combining a push/rotary encoder, multicolor encoder ring, four programmable buttons, and a high-resolution LCD, the EC-4BV delivers precise, flexible, and visually informative control for professionally installed audio environments.

System Integration & Configuration

The EC-4BV connects using a single Ethernet port, providing:

  • Configuration

  • Control and monitoring

  • Power via PoE (Power over Ethernet)

All functionality is programmed using HiQnet™ Audio Architect, with a familiar drag-and-drop configuration workflow that simplifies system design and commissioning.

Encoder & Button Control

Push/Rotary Encoder

  • Rotate for continuous parameter control (e.g. volume)

  • Press for binary control (e.g. mute) or preset recall

Encoder Ring

  • Multicolor, backlit LED ring

  • Can display a bouncing audio meter

  • Temporarily shows volume level during adjustment

  • Temporarily displays binary states (e.g. red/green mute status)

Programmable Buttons

  • Four multicolor backlit buttons

  • Binary control (mute/unmute)

  • Preset recall

  • Source selection

Each control element supports up to eight colors with adjustable brightness, providing clear visual feedback for system status.

LCD Display

  • Resolution: 64 × 128 pixels

  • Multicolor backlit

  • Displays custom text, labels, and system feedback

  • Designed for high visibility in both bright and low-light environments

Multiple Modes of Operation

The EC-4BV supports multiple operating modes, allowing the push/rotary encoder and encoder ring to be dynamically reassigned based on which button is selected. This enables powerful multi-function control from a compact, single-gang interface.

Sleep & Security Features

To reduce visual distraction, the EC-4BV includes a sleep function that turns off all LEDs after a configurable period of inactivity. Any user interaction instantly wakes the controller.

Security features include:

  • Remote lock/unlock via control systems

  • Local unlock using a four-digit PIN entered on the buttons

This makes the EC-4BV suitable for public, shared, or unattended spaces.
