    Audio board line I/O connections

    Hi, I am trying to establish all the components that I will need for my new project: https://forum.pjrc.com/threads/54862...uencer-Sampler

    And after a lot of reading and searching I have not found any place where the line input and output connections for the Audio Board are explained. Could anyone confirm whether the following conetions are right?

    With TRS 1/4 jack:


    With TS 1/4 jack:


    I have some doubts about the schema. Specially with the TRS option, as I see 5 pins. In the example I am not using the upper pins and I am using the same ground pin for both channels. I am not shure if that is correct.

    I assume that with the audio shield I can connect the jack sockets directly to the input/ouput pins and I have no need to create the following schema, as it applies only to the Teensy's ADC input:


    Is that correct?

    Thak you for your attention.
