ROHM BD37524FS handbook
BD37524FS is a sound processor built-in 3-band equalizer for car audio. It has functions of stereo 5ch input selector, input-gain control, main volume, loudness, 5ch fader volume, LPF for subwoofer, level meter. The advanced switch circuit can reduce various switching noise.
ROHM BD37513FS handbook
BD37513FS, BD37514FS, BD37515FS are sound processors built-in 2-band equalizer for car audio. The functions are stereo 4ch input selector, input-gain control, main volume, loudness, 5ch fader volume (About BD37513FS, 4ch fader volume are available). 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.
ROHM BD3460FS handbook
BD3460FS,BD3461FS,BD3464FV,BD3465FV are 4ch/6ch electronic volume which has audio efficiency of the industry best level. It has 『Outside sound mixing function (with volume)』(BD3461FS, BD3465FV) in favorite channel to mixing of the portable telephone and car navigation’s guide sound. Also, which has 『Ground isolation amplifier』(BD3460FS, BD3461FS) when connecting with the outside voice inputs such as portable audio and car navigation. It is lineup and possible to be chosen to the use by it. Also, Rohm has the volume switching shock sound prevention technique “Advanced switch”. Therefore, it supports the construct of the high quality car audio space by the simple control.
ROHM BD3452KS handbook
BD3452KS is a sound processor that integrates functions including Input Selector, 8ch Volume and Gain Amp for applications such as AV receivers, home theater systems and mini-component systems. Adopting the BiCMOS process achieves low distortion, low noise and a wide dynamic range.
