* 1 Signals of 1kHz, 20mV are applied to the input of the both channels, adjust sinking current into the Pin13 to 15µA±5%
Standard value at VCC=3V is about 1kΩ.
* 2 External circuit should not be connected with the Pin21. Connected in the IC.
* 3 Users should follow the latest technical information from dbx company. Constant number might be changed.
Note 1) All the resistors and the capacitor with the mark should be used in the error less than ±5%.
Note 2) Impedance of the input signal source should be less than 100Ω.
