I have a CD player with adjustable balanced outputs and wanted to set them at the proper level. For the rest of my equipment I feed a 0.775V (0dB) tone from an audio oscillator into the board and adjust, if necessary.
I can't use that approach with a turntable or a CD player which is why I bought the test CD 3 to be able to generate a test tone from within the player.
Test tones on the CD have levels given, for example -20dBFS. I don't know what the FS means but i assumed that the recording level was at -20dB, but that seems to be wrong.
Where is my error and what are the recording levels on this CD?
