: Pins 3, 4, and 38 emit low-level raw analog audio signals. To prevent low-impedance loading or distortion, pass these channels through a basic op-amp mixer circuit or a common LM386 amplifier stage before driving headphones or standard speakers. Decoupling Capacitors : Place a ceramic decoupling capacitor physically close to Pin 40 ( VCCcap V sub cap C cap C end-sub ) and Pin 31 ( GNDcap G cap N cap D | Feature | KC89C72 | AY-3-8912 | Yamaha
