How to operate the Sound Adjustment Mode
• The crossover function is a filter that allocates specified
frequency bands.
• A high-pass filter (HPF) is a filter that cuts out frequencies
that are lower than the specified frequency (bass range) and
allows higher frequencies (treble range) to pass through.
• 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 is 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.

When this deck is in advance mode, it corresponds to basic
speaker systems which comprise front speakers, rear speakers
and an added sub-woofer if necessary. 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.
