iceblinkfroufrou Posted July 5, 2016 Posted July 5, 2016 I have a Harman/Kardon stereo receiver and i'm wondering if it would be possible to hook up one of those old graphic equalizers that you see in pawn shops and the like, would it actually work? The tone control on the receiver is crap imo, 1-10 for the bass, 1-10 for the treble, thats it. Also are there modern equalizers these days? Thanks.

Graphic equalizers are what used to have to do before we got proper auto room eq itchy . If your HK receiver has separate pre amp out main amp in jumper leads [ if its really old ] thats 1 way . Another is a tape monitor circuit [ when we had 3 head cassette decks this was handy] what model is your receiver ? old graphics only add to the thd and noise of your system ; some have better octave coverage than others and some have specific parametric frequency capability to better cover things like rolloff and q . Your receiver may have a tone control bypass switch ;thats for passing through a more pristine signal and why you only have bass and treble controls ; in the old days you may have had a midrange control as well or frequency shelving controls for the bass/treble .. Thesedays you can do much better with something like a minidsp product which operates in the digital world for processing after its ad converter https://www.minidsp.com/products/minidsp-in-a-box/minidsp-2x4

Yes waroon yamaha for one has a good parametric as has my sherbourne but itchy has a stereo 2ch receiver which like practically all doesnt . Most have simple circuitry so as not to 'corrupt' the pre amp level signal . It's the HK3770 No pre amp outs but it does have record outs so you could feed a minidsp if you wanted to run a REW program on your pc for it ; if its important to you ? Ime a multichannel guy so no need for the dsp processor personally .

Graphic equalizers were out there in old days to hopefully recover/compensate the loses of Vinyl & Cassette decks due to their inherit low dynamic range, signal to noise ratio, so on. With modern digital technology, you don't need any equalizer. With even low quality equipment you do get decent dynamic range, signal to noise ratio and bloody good sound. If you want to play with it anyway, just like mentioned above, all the AVRs come with EQs even for separate ones for each channel not just one controlling the all channels. If you absolutely want to stick to your HK, yeah any EQ should work with it, but don't think it is worth the hassle. Back in 2005 when I upgraded my system, I tried to use my professional quality 2x12 channel EQ, it worked but it actually made the sound worse so I chucked it in the bin thinking one would never need an EQ for home HIFI.
