Setting up ELTSI-1/Line End Transponder

This article will explain how to setup and configure the ELTSI-1/Line End Transponder in a system.

The line end transponder ensures reliable monitoring of the loudspeaker lines. Where impedance measurements may result in an erroneous report of a broken line, the line end transponder will always report the correct health of the loudspeaker loop.
Up to 10 line end transponders may be connected to the same amplifier output, making it possible to branch out the loudspeaker loops.

Setting the address

Each amplifier can have a total of 10 LETs (ELTSI-1) divided among the channels and each ELTSI-1 must have a unique address.
