●Description The Sound Processor with built-in 2 Band Equalizer, incorporates functions required for BOOM BOX and mini-component systems, such as input selector, input gain amp, volume, surround, tone (bass, treble), and loud speaker equalizer (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.
