BD37034FV-M
General-Purpose Electronic Volume with Built-in Advanced Switch
BD37034FV-M is sound processors for car audio. The functions are stereo 5 input selector, volume, 3-band equalizer, loudness, 6ch fader, mixing, HPF for front and rear, LPF for subwoofer, anti-aliasing-filter, Hi-Voltage output, output level detector. 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.
