CROWN EOL BOX - End-of-line terminator

The termination is placed at the far end of the loudspeaker circuit. Unlike most loudspeakers, the EOL box is reactive at 20kHz, so the resulting current can be measured using HiQnet Audio Architect™ software. If the circuit is open or shorted, the current measured at 20kHz will change. The EOL box presents a 10Ω or 5Ω load at 20kHz, selectable via an external impedance switch. This method requires the 20kHz pilot tone to be mixed with the audio. The pilot tone can be generated within the DCi Network or Dante family of amplifiers, and the USP4 family of CTs. Additionally, the built-in DSP in DCi Network, Dante, and USP4 has the ability to allow the pilot tone to bypass the loudspeaker's internal processing.
