Frequently asked questions
What do these products do, and are they used together?
The EOL Box monitors speaker circuit health by detecting impedance faults at the end of speaker runs. The XLi 1500 amplifies audio signals to drive speakers. They serve different roles: EOL Box is diagnostic; XLi 1500 is amplification. They could be used in the same system but address separate functions.
Which product is for live sound reinforcement?
The XLi 1500 is designed for live sound reinforcement, worship spaces, and entertainment venues. The EOL Box is a support tool for system technicians maintaining speaker circuit integrity, not a direct amplification or performance device.
What amplifier compatibility matters for the EOL Box?
The EOL Box requires Crown DCi Network or USP4 family amplifiers to function properly, as it relies on the 20 kHz pilot tone passing through the amplifier's DSP architecture. It is not compatible with other amplifier brands or older Crown models.
What power and speaker flexibility does the XLi 1500 offer?
The XLi 1500 delivers 450W per channel at 4 ohms, 330W at 8 ohms, or 900W bridged mono at 8 ohms. It supports stereo, parallel, and bridge-mono modes with both RCA and XLR inputs, making it adaptable to various speaker configurations and installation scenarios.
