The EOL box is used as an End of Line (EOL) termination in audio systems that use a 20kHz pilot tone to detect open and short conditions. The termination is placed at the farthest end of the loudspeaker circuit. Unlike most loudspeakers the EOL box is reactive at 20kHz such that the resulting current can be measured using HiQnet Audio Architect™ software. If the circuit is either opened or shorted, the measured 20kHz current will change. The EOL box presents either a 10Ω or 5Ω load at 20kHz, selectable using an external impedance switch. This method requires the 20kHz pilot tone to be mixed together with the audio. The pilot tone can be generated within the DCi Network or Dante family of amplifiers and the USP4 family of CTs amplifiers. Additionally the DSP built into the DCi Network, Dante and USP4 has the ability to allow for the pilot tone to bypass the internal speaker processing.

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

The EC-V contains one push/rotary encoder and one encoder ring. The encoder ring is multi-color backlit, capable of eight different colors 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 EC-V supports ‘sleep’ functionality. After a specified amount of time with no user input, the EC-V 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-V can be remotely locked and unlocked via other control systems.
