The highest and lowest bands can also usually be used for shelving.
Vinyl high frequency roll off.
If you have a question or video suggestion leaving a comment is the best way to get me to see it i try to.
Perhaps if they d placed the roll off just above 24 khz there d have been no pushback.
At high frequencies to at least 20 khz.
The manufacturers recognizing the potential issue of boosting high frequencies indefinitely added a high frequency roll off above the highest frequencies human adults can hear above 20 khz.
Some prefer that over sharp cutting resonant filters.
And g day back to you.
This is good although a bit extreme.

Well spotted and yes it is an issue that most vinyl users seem blissfully unaware of.
An essential feature of all cutting amplifiers including the neumann cutting amplifiers is a forcibly imposed high frequency roll off above the audio band 20 khz.
That is they can roll off frequencies above or below in which case they act as a low pass or high pass filter respectively.
Any comments would be appreciated.
The roll off rate above that frequency was dependent on the recording bias setting used but ranged between just 6 to 12 db per octave much gentler than the unnatural cd brickwall filter.
I have some lp s that i hear zero high end roll off towards the inner grooves yet others i feel like my ears are getting clogged towards the end of a side.
So flat to 20 khz possible but thanks to the mastering high cuts usually the rolloff starts at 15 khz what dont says that there is nothing happening above 20 k but thats mainly noise nice analog high frequency noise at the borders of perception for a nice high frequency smoothing.
Here the filters mostly make do with a basic 6 db 8ve roll off however some instruments provide a switchable 35 hz filter at the high frequency end with a faster roll off to help filter out noise generated by muscle activity.
And yes as you also.
I cannot find any ryhme or reason as to why some lp s exhibit different levels of this roll off.
It depends on the lp for me personally and the stylus and or cartridge.
25k was the sales argument for the better vinyl pickup systems.
Is this high frequency roll off not considered relevant in the listening context.
