EOL Box End-of-line Terminator

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 10? or 5? load at 20kHz, sele...
