Specification
For the first test, all the main channel signals should have very similar frequency response curves,
rolling off at lower frequencies. The Sub signal redirected from the front speakers should be distinct
and around 10dB higher than the other channels at low frequencies. If Simplified Bass Management is
used, the Left and Right outputs will show a flat response and no bass will be redirected to the Sub.
For the second test, the Left and Right frequency responses should be flat. If Simplified Bass
Management is used, there will be no signal from the Sub present at the Left and Right outputs.
