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 normal 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.
In addition, in pro mode, the adjustments can be made to suit
speaker system where the front speaker, rear speaker and
non-fader output can be switched between Hi, Mid or Low
output and the speakers can be combined according to each
range (treble range: tweeter, medium range: Mid, bass range:
woofer) to provide 3-way playback. In this case, the crossover
function can be used to adjust the playback ranges so that the
HPF is applied to the treble-range speakers, the HPF and LPF
is applied to the medium-range speakers, and the LPF is
applied to the bass-range speakers so that the sound from all
speakers merges properly.
