I just set up my Technics MK2 1200 with a Denon dl 160 cartridge-- and last night I played the Hi-Fi News record. During the Bias check tones on side 3, I heard no distortion on the 1st of the three tones, but there was buzzing in the right channel on the 2nd. According to this setup guide I've got to adjust the bias, and by this I understand it to mean the Anti-skating. But I moved the anti-skating dial to match the tracking weight setting on the counter weight. But this didn't change the distortion. (The tracking weight had been set for 1.9, 1.6 +/- 3 being what the DL-160 specifies in its instructions-- I'm not using a tracking force guage) What should I do? Adjust the tracking Weight? why doesn't the tracking force setting affect the buzzing?Should I be using a tracking force gauge?Thanks anyone.
I'm not sure what I'm looking for with this test on the Hi-Fi News, as seen in this youtube video:http://www.youtube.com/watch?v=guDmz2ILuo4When I did this test yesterday with the same setup, I can't tell where the maximum vibration is occurring -- it starts vibrating at maybe 15hz and starts to wane only at 7hz. Is this bad, should it be clear where the max vibration is occurring? In the video, i can't see the vibration, but the audio seems to indicate the most vibration is around 9hz in the test.
"The HFNRR frequency sweep is crap. Do not use it.The reason should be clearly obvious if you open it up in Audacity in a spectrogram view: the sweep speed is nowhere near constant. In fact, it speeds up significantly around 700hz.... which, not coincidentally, is right around where the frequency response drops in your plots.My (cynical) hypothesis is that Len Gregory mastered this track by manually turning the dial on an oscillator from 20hz to 20khz. He did advertise that this was an all-analog mastering..... bleh."
