Yes, yes, I am a new here and only ever read these forums
usually for a laugh, and have posted this time because I feel the need to.
I'll post this once
just for the ignorance of those that believe all Class-D have the next to no
phase shift from the upper/mid right up to the highs. It has been quoted
to look at graphs of x Class-D as it "only" has x phase shift and
they used this to compare it to other Class-D modules. Some even being cheap
subwoofer modules used.
It's false, and those
here who “consider themselves” to be EE’s should know better, you know who you are and should lay low to
giving your tick of approval to this garbage.
Because some of these
comparison modules are measured with/without their output filters insitu, and
the manufacturer has used Audio Precision "very high order" external “test
filtering” instead for the graphs, and/or the frequency knee of the output
filter they use if used, is totally different to the one it's being compared to
by the one doing the comparing, which will directly effect the amount of phase
shift down lower in the audio band as those of us all know.
This thread is just plain bunkum.
