Re: Freelancer HELP needed

Thank you, and yes it worked for line in, very clear audio

Condenser microphones, I need an external power and preamp box to test

I used audio technica Condenser Shotgun Microphone with preamp and audio is very weak, I seems to need the write specs for the external preamp

I was able to record, as you said, only when I used plughw it worked

Strangely the audio file is silent, no audio, but the files were generated

My question, I am using condenser mics, what is the power spec for the inputs, maybe thats why I didn't record anything
