BD37033FV-M
Sound Processors for Car Audio
BD37033FV-M is sound processors for car audio. The functions are stereo input selector with single end 3 and ground isolation input 2, volume, 3-band parametric equalizer, loudness, 6ch fader volume, LPF for subwoofer, anti-aliasing-filter, Mixing volume. Moreover, “Advanced switch circuit”, that is ROHM original technology, can reduce various switching noise (ex.No-signal, low frequency likes 20Hz & large signal inputs). “Advanced switch” makes control of microcomputer easier, and can construct high quality car audio system. A Product Change Notice (PCN) is scheduled for this product.
While there will be no changes to electrical characteristics, certain specifications will be updated.
