(2) Setting the loop gain
(3) ALC function and microphone amplifier input
• Set the LPF constant and pin 12 control voltage so
• Refer to items 7 and 8 in “Circuit description.” When

that the loop gain (1st echo wave / 2nd echo wave)
does not exceed 1. Be particularly careful of peak-
ing near the LPF cutoff point.
these functions are not used, be sure to ground pins
27 and 28 (the ALC function) and pins 29 and 30
(microphone amplifier input detection function).
