What is the maximum length of cable that can be on the microphone and headphone lines?
One can calculate this having at hand the specs of the cables (loss/attenuation), peripherals and knowing the input and output characteristics of the module in use.
I want to use 150m cable. Which cable is better for this distance? Working with GL865.
150 m is a really long distance, but youa are welcome to take a look at the attached document to see how to realize such a long wire avoiding as much as possible audio noise.
