Operating Precautions and Application Methods (Pin No.: (P/F))
1. How to determine tone controlled frequency characteristic time constants
Bass characteristics determining elements: CL, CLB terminals ((4/5), (5/6), (16/19), (17/20)) Figure 1
Low-bandwidth cut-off frequencies fL1, fL2, fL3 of bass characteristics are determined by the following
equations :
fL1 =

Figure 1 Bass characteristics
(during boosting)
Under reference circuits of CL = 0.33 µF and CLB = 10 µF, setting is made as follows:
fL1 1.59 Hz, fL2 15.9 Hz, fL3 48.2 Hz
When the characteristics during boosting are considered, crossing with 0dB axis is made at fL1, increase
starts by 20dB/dec., and flat characteristics of Gain = 20dB is obtained at fL2.
Low-bandwidth f response is determined at fL3-namely, CL and gain starts decreasing from fL3 by 20dB
/dec.
As explained above, low-bandwidth characteristics can be varied by varying CL and CLB.
Treble characteristics determining element: CH ((3/4), (18/21))
Figure 2 High-bandwidth cut-off frequencies f H1 and f H2 of treble characteristics can be determined by
the following equations:
f H1 =

Under reference circuit of CH = 0.0082 µF setting is
made as follows:
Figure 2 Treble characteristics
(during boosting)
fH1 1.94 kHz, fH2 = 19.4 kHz
As explained above, high-bandwidth characteristics can be varied by varying CH.
By creating the status of CL decrease and CH increase, low/high bandwidth gains
(f = 100 Hz, 10 kHz) increase but gain near f = 1 kHz is also increased.
On the other hand, when the status of CL increase and CH decrease is created, take note that gain
near f = 1 kHz approaches 0dB while low/high-bandwidth gains are decreased.
2. Loudness control
By connecting pin (9/11) (loudness terminal) to pin (8/9) (volume terminal), “Loudness” status can be
created. Loudness boost amount is determined by pin (9/11) DC voltage (refer to the subsequently described
GV-V (9/11) data).
Loudness is controlled by considering that sound levels will become uniform for all frequency levels
through increasing low/high-bandwidth gains when volume is reduced-namely, sound volume is low.
When loudness control is not used, connect pin (9/11) to pin (10/12) (reference terminal).
The capacitor (typ. 0.047 µF) between pin (9/11) and GND is for reducing pop sound during loudness ON
while the capacitor (typ. 1 µF) between pin (8/9) and GND is used for the same purpose during loudness
OFF.
