I can often sense the HF above 8KHz which is fairly common and relatively easy to pick out.
Now since I’m limited to how far I, see the HF on the Technics SH-8055
25Hz 63Hz 100Hz 160Hz 250Hz 500Hz (1KHz 2KHz 4KHz 8KHz 16KHz)
Anyway I’ve patched the centre out the spectrumlab, changed the settings for higher frequency resolution.
Okay now, this might be an old film but at the time, it was rather state of the art in Dolby stereo SR.
The cat-scan scene in Alien3 (1992) chapter 19 region 2 DVD shows sharp edge high end that pinches on the ear.
I’m presently readdressing the HF for smoother flatter response and bit of extra boasting on the amps (not too much only what I need for the room). A little of the usual audio limiting will be applied for HF protection.
The blinding bright yellow with patches of orange on part 1 lower part is where the record graph starts from and ends at the top. (12 KHz 18 KHz)
Part2 between (17 KHz and 18 KHz)
