Sound Processors for BOOM BOX / Mini-component Stereo
Sound Processors
with Built-in 2-band Equalizers
BD3870FS,BD3871FS,BD3872FS,BD3873FS
●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.
●Line up matrix
