Features
e * Linear phase filters (Bessel function type)
realize natural and equal sound levels in and
around the passband frequency.
Hi-fi electrolytic capacitors especially
designed for dynamic sound reproduction
e Phase inversion switches for checking easily
a sound continuity between mid and high
range speakers
* 180 Hz mid cut controls with Q switches for
adjusting a low and mid-low sound
¢ 40 Hz bass boost control for dynamic bass
reproduction
* Linear phase filters (Bessel function type)
Most of the channel dividers currently available
employ flat response filters (Butterworth type). The
group delay characteristic of this type of filters is
much worse than that of the linear phase filters, and
this causes transient distortion in the audio signals at
each filter's crossover frequency. To reduce that
distortion and to obtain hi-fi sound, linear phase
filters (Bessel function type) are used for the
XEC-1000. :
