The VM9020TS has a built-in Pink Noise generator to help
set the relative speaker levels for multi-channel audio
playback.

signal will be converted to 48kHz. When Down Sampling
is OFF, the original sampling frequency is preserved.

to 80Hz, then the high pass SMALL speaker crossover will be
set to 90Hz.
