So here's a pic of my Kenwood Basic C2 preamp.. What does "Turnover" knobs do? And What does the Filter buttons do? (Subsonic, Low, and High) |

Google is your friend. The manual is freely available online. Turnover is the center frequency of the bass control oand treble control. Ex: bass has 200, off and 400. If its off, then the bass control knob should be inactive. If its set to 200, the frequency range around 200Hz is affected. Same with 400Hz. Listen to the difference. Just remember, these are slopes, not a specific narrow band that only affects that frequency. As I said, listen to the difference.
The subsonic is a high pass filter that limits the frequency range at the lower end of the spectrum. I’m not sure what ranges they cover. If you have very good speakers that play full range, leave this off. If you don’t have large speakers, this can be used to protect your speakers from playing the lower frequency ranges.

Yeah, the manual doesn't really explain it in a way I can understand. I was kinda looking to get some layman type explanation..  |

Added some close ups to original post.
So for Turnover... if I turnover at 200hz, does that mean when I adjust bass I'm adjusting bass for 200hz and below ? Or jist 200hz? Ditto for 400hz

That makes a lot of sense now. My owner's manual doesn't really explain it line you did. I understand the low and subsonic explanation.. why would I want to filter high freq? Subwoofer related? I'm running klipse RF-62ii floorstanding speakers... they seem to sound a little better with lowest filter on. Kinda depends on music. Klipsch specs have them at 35hz to 24khz for freq response. I have turnovers set at 200hz and 3k hz.. this seems to sound very good. Although I still don't fully grasp whats going on. But I have a much bettergrasp Thanks! |

Think of a normal bass knob and a normal treble knob (commonly called tone controls). These adjust the sound centered at your selection, but they have a slope. When you adjust at 200, you’re really adjusting from about 50-60Hz to 300-400Hz and everything in between. Think of it as a ramp on both sides with 200 in the middle and the slopes go downward from 200 each way. Setting the turnover doesn’t do anything unless you adjust the tone control below it + or -, which I see you did from your pictures. I think the 8k filter may be used if you have very bright tweeters or you use an old tape deck with no dolby noise reduction.

I think I understand this stuff much better I captured this from owner manual for my preamp.. it is the specs for turnovers and filters.. Attachments:
