•Operation notes
(1) LINE OUT (pins 1 and 2) signal processing
• Be sure to attach a capacitor for phase correction to
the LINE OUT pins.

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