Okay.

1. High frequency crystal clear: AD827 operational amplifier has high gain bandwidth and high speed characteristics. AD827 can transmit clear and delicate audio signals in the high frequency range, retaining the music details in the high frequency part and presenting a crystal clear effect.

2. Superior low-frequency bounce: The AD827 op amp performs well in the low-frequency range and has excellent low-frequency response and flexibility. It can accurately transmit low-frequency signals and maintain the dynamics and sound quality of the low-frequency part.
