How to operate the Sound Adjustment Mode
●A low-pass filter (LPF) is a filter that cuts out frequencies that are
higher than the specified frequency (treble range) and allows
lower frequencies (bass range) to pass through.
●The slope is the signal level at which frequencies that are one
octave higher or one octave lower are dampened.
The larger the slope value, the greater the slope. In addition,
when "PASS" is selected, the slope is eliminated (sound does not
pass through the filters), so that the crossover function has no
effect.
This deck corresponds to basic speaker systems which comprise
front speakers, rear speakers, and subwoofer. In such cases, the
crossover can be used to apply the HPF to the front and rear
speakers and the LPF to the sub-woofer so that the sound from all
speakers merges properly.
Multi-harmonizer
When original sounds are converted to MP3/WMA and Memory
Stick (ATRAC3) format, frequency ranges that are not normally
audible to the human ear are compressed. The multi-harmonizer
can be used to play back these compressed sounds at as close to
their original form as possible so that clear and powerful sound can
be enjoyed.
