What is the difference between their label "Line Level" and a pre out? Nominal level is the operating level at which an electronic signal processing device is designed to operate. As they have not specified their levels it is perfectly normal to assume that the signal levels are referenced 0dBV and hence +6dB is a good level to stress the device under test.Nominal line level is -10dBV or 0.316V RMS. To their defense, they didn't write pre out.
Besides, if you want to be pedantic, line level means it is to feed a line and hence a more robust and higher level signal is to be expected.
