特点:

  • Using extemal components,center frequencies and Q factors of the bass characteristics are flexible.
  • Providing a mute switch onto one of the input pins allows cross-talk suppression.
  • A surround function can be constructed without external components.
  • Enargy-saving design resulting in low current consumption,by utillizing the BiCMOS process.
