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.

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.
