Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
When you say you cant get the line input to record from a direct feed from the sound system. What exactly do you mean by direct feed from the sound system.
Is there an external sound system you are trying to record from and if so, whats the full name brand and model of that system?
If you meant something else, please explain..
Thank you for your response,
