Maximum length of Audio cables

  1. What is the maximum length of cable that can be on the microphone and headphone lines?

    1. 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.

      1. I want to use 150m cable. Which cable is better for this distance? Working with GL865.

        1. Hi Micael,


          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.
