processes the signals to solve the above-mentioned problem of sound playback system as follows:

f(Hz)
By dividing the input signal into three frequency bands, the bass (20Hz to 150Hz), middle range (150Hz to 2.4kHz) and
by combining them, the phase difference 180
°
is made between the bass and middle range and 360
°
between the bass
and treble.
Time delay characteristic in every frequency is adjusted through such phase difference and, therefore, the distortion of
rising edge of sound can be minimized.
Amplitude correction (Harmonic correction)
High-speed detector and high-performance VCA circuit controls the amplitude of treble constituent to keep appropriate
audibility balance at the treble which consists of harmonics. Correction value is decided by both operations at two kinds of
levels; one level is set up by serial control from an outside source and another one is obtained by detecting an input signal.
The amplitude of treble input into VCA is corrected by an internal control signal obtained through such operations. By this
amplitude correction, the harmonics is recovered and the definition level of musical instrument or voice can be enhanced.
Bass boost
The bass constituent is boosted to keep well balance to the treble constituent varying dynamically.
The boost is fixed to 5dB (Typ.) at f
=
100Hz by an internal circuit and it cannot be controlled externally.
