Crown GEOLBOX End-of-Line Terminator Box

Crown EOL Box for Audio System Monitoring
The Crown EOL (End of Line) Box is an essential component for audio systems that require real-time monitoring of loudspeaker circuits. Designed to be placed at the farthest end of the speaker circuit, this termination device detects open and short conditions by utilizing a 20 kHz pilot tone. Unlike traditional loudspeakers, the EOL Box responds to this specific frequency, enabling accurate detection of potential system faults. The monitored circuit's 20 kHz current is measured through the HiQnet Audio Architect™ software, providing technicians and system integrators with critical insights into the health of the audio system. This makes the Crown EOL Box an invaluable tool for ensuring reliable performance in large-scale, complex audio setups.

Key Role in Circuit Health and Fault Detection
The primary function of the Crown EOL Box is to provide termination that ensures the integrity of the speaker circuit is constantly monitored. By using a 20 kHz pilot tone, the EOL box helps identify faults such as short circuits or open circuits that may otherwise go unnoticed. The box is reactive at 20 kHz, allowing it to measure the current and immediately alert users to any issues. This proactive fault detection enables swift maintenance and avoids potential damage to speakers or amplifiers, minimizing downtime during live events or installations.

Adjustable Impedance for Custom Setup
One of the standout features of the Crown EOL Box is its ability to switch between two different impedance settings: 10 Ω and 5 Ω. This versatility ensures compatibility with a wide variety of audio systems and speaker setups. The impedance can be easily adjusted via an external impedance switch, allowing for greater flexibility during installation and configuration. Whether your system is designed for high-power or low-power applications, the Crown EOL Box ensures that the circuit termination is tailored to meet the specific needs of your setup.

Integration with HiQnet Audio Architect for Seamless Monitoring
For users looking to integrate the EOL Box into their networked audio system, the device is fully compatible with HiQnet Audio Architect™ software. This software provides intuitive control and monitoring capabilities, allowing for real-time tracking of the audio circuit's health. The 20 kHz current measurement is processed through the software, which alerts operators to any changes in the signal—whether caused by an open or short circuit. This integration not only simplifies troubleshooting but also enhances the overall reliability of your audio system by providing continuous feedback.

Compatibility with DCi Network and USP4 Amplifiers
The Crown EOL Box works seamlessly with the Crown DCi Network and USP4 family of amplifiers, both of which are capable of generating the 20 kHz pilot tone required for operation. The DSP functionality built into these amplifiers allows the pilot tone to bypass the internal speaker processing, ensuring accurate monitoring at the farthest point of the circuit. This compatibility extends the functionality of the EOL Box, making it an ideal solution for large-scale installations or any project that involves the integration of Crown amplifiers and advanced monitoring systems.
