Between Pin14(26) and Pin15(25) Add 10K of resistors between Pin14(26) and Pin15(25), can adjust the difference between the sound level of Focus ON and the sound level of Focus OFF. Also add 10K of resistors between Pin14(26) and Pin15(25),can decrease the Focus gain. Then the maximum input voltage and the output noise voltage can be improved. (Reference) In the case of

NOTE
Each switches (SRS ON/OFF, FOCUS ON/OFF and FOCUS Position H/L Switches) does not have the countermeasure for click noise, so that we recommend outside mute circuit.
