FOperation notes

(1) Operating power supply voltage range

As long as the operating power supply voltage range and

ambient temperature are kept within the specified range,

the basic circuits are guaranteed to function, but be sure

to check the constants as well as the element settings,

voltage settings, and temperature settings. Also, volume

curves sometimes depart from target values when there

is a combination of low temperature and reduced power.

(2) Primary amp

S The input impedance is 47kΩ.

S A buffer if R and C¹are not present.

S The gain can be set by R and the 20kΩ.

G^VC= (R + 20kΩ) / R

Note: Set C²(input coupling) and C1 (used to set the

gain) depending on the frequency band used.

(3) Bass filter

S The BPF is composed of a multifeedback active filter.

f^ocan be varied according to the value of C.

Note: Filter gain is calculated using the equation on the left. Total output gain is the

sum of the gain for each of the internal circuits.
