How
to
operate
the
Sound
Adjustment
Mode
For example, when adjusting the
HPF,
frequencies that are lower than the specified frequency are
progressively dampened, rather than simply not being played back at all. The "slope" adjustment
function is the function that is used to adjust these dampening characteristics.
The slope characteristics
of
a filter are such that with larger slope values (for example
12
dB/oct),
the slope becomes steeper, and so the amount of sound mixing
in
with neighboring bands becomes
less
so
that only the target band is played back. However, it also causes the merging of sound
between speakers to become poorer and can result
in
greater distortion.
• The crossover function is a filter that allocates the 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.
When the 4-speaker layout is selected, 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.
When the 3 way layout is selected, 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.
