The result when waveform is input from CTLHEAD (+) pin and ANOUT pin is monitored after performing
coupling electrolytic capacitor (10μF) of CTLHEAD (–) and CTLHEAD (+), and coupling electrolytic capacitor
(10μF) of HEADL (–) and HEADL (+), CTLFAMPI (–) and CTLFAMPI (+) , and CTLFAMPO and CTLSAMPI.
Gain is maximum –1.5dB lowered when waveform is input from CTLHEAD (+) pin.
