Crown End-of-line Terminator
Crown End-of-line Terminator The Crown 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, 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 family of amplifiers and the USP4 family of CTs amplifiers. Additionally the DSP built into the DCi Network and USP4 has the ability to allow for the pilot tone to bypass the internal speaker processing.
About Crown AudioAcquired by Harman International in March of 2000, Crown has continued to move forward, producing numerous innovative designs, such as the DriveCore™ Install (DCi) series that was released in 2013. This series features both analog and Network amplifiers for the installed sound market. Using just one tiny chip to replace over 500 parts makes the DCi series of amplifiers the most reliable and innovative amplifier on the market today. These products and more embody the reliability and innovativeness that have long been the manufacturer’s hallmarks. Crown today continues to delight its customers with products that consistently exceed both specifications and expectations, even on the most demanding tours and installations.
