<Test condition>
1. Before the Test (AutoVolume, PEQ, Bass EQ,
ClearVoice and Surround Effect are “off”)
* PEQ: Parametric Equalize
2. Open the test file, “ Stereo test(autovolume test).at27”
3. Check the reference. signal, the difference of volume
levels should be about 2dB.(Adjust Low Level Percentage
in Analog Generator)
4.Then, AutoVolume “ON” and capture the waveform.
5.Compare the captured waveform with the reference
waveform.
