10086EAT02 ●Description The Sound Pr ocessor with built-in 2 Band Equalizer, incorporates functions required for BOOM BOX and mi ni-component systems, such as input se lector, input gai n amp, vol ume, surroun d, tone (b ass, treble), an d lo ud speaker e qualizer (BD3872FS only).
These functions can be controlled through the two-wire serial control.
●Features 1) Using external components, center frequencies and Q factors of the bass characteristics are flexible.
2) Providing a mute switch onto one of the input pins allows cross-talk suppression.
3) A surround function can be constructed without external components.
4) Energy-saving design resulting in low current consumption, by utilizing the BiCMOS process ●Applications BOOM BOX, mini-audio systems, and micro-audio systems.
