• Adjustment method:
band filter cuts only the limited frequencies to minimize influence
on the quality. Therefore, its effect cannot be obtained unless the
set accurately to the causing resonance
and waves. The band filter can adjusted according to what
you feel through but we recommend the of a signal
or a spectrum with fine frequency measurement
adjustment.
• Adjustment using a signal generator:
Output sine wave, vary its frequency to find the frequencies at which
the or volume increases (standing waves
occur), and control to position with WhiCh the
resonance and standing waves disappear.
• Adjustment using a spectrum analyzer:
white noise (sound in which all frequencies
frequency observed on the
control to the position with which
the spectrum analyzer disappears.

The band reject filter can solve the problems of resonance or unclear sound
with minimum influence on the sound because it eliminates only the
frequencies causing resonance or waves.
