Nonsense. The routine use of equalization during the recording process
dates back to no later than the early 1950s with the introduction of the
Pultec equalizer. Digital equalizers have only been in routine use since the
late 1980s. That means that for over 40 years and tens of thousands of
recordings, analog equalization has been the rule. Trevor is implicitly
dismsising the vast majority of all LPs and analog master tapes. Program
equalization during recording and production is almost always done by ear.
The real problem is that the high end audio industry has suceeded in
creating a global hysterical fear of program equalization in the minds of
most of their consumers. Audiophiles have been mis-educated to believe that
they have change out parts of their system to adjust sonic balance, rather
than use equipment that is designed to have frequency response that is
adjusted by the end-user. Certainly, this is a good strategy for getting
consumers to churn their systems and produce used but servicable equipment
that dealers and mark up heavily and sell used.
Back in the late 1960s when consumer equipment with equalizers first came
out, a number of dealers shared with me that they feared that this feature
would become popular, and that consumers would be able to make inexpensive
equipment sound better than "it should" to optimize the dealer's profits.
Trevor, we've already been over this. For adjusting bass levels for
different recordings, tone controls are by far the best way to go,
IMO.
In fact, the tone control technology of choice for bass, treble and anything
in-between is parametric equalization.
I'm not talking about room correction, here.
Room correction is best applied by acoustic means, at least until a fairly
high level of refinement has been achieved. Electronic equalization of most
room faults is usually a band-aid at best, and a figuratively a fairly
small, ineffective and dirty band-aid at that. However a dirty band-aid can
be better than nothing at all.
I don't want to have this discussion in this thread. I know what
works for me.
That seems to be the rule of Dizzy - don't bother him with the relevant
facts.
However, Trevor's idea of the facts can be a mixed bag. Sometimes he has
things right, and then there are the other times. Now that ME went out of
business and his livlihood no is no longer tied to damning power amps with
negative feedback, Trevor at least can start making some sense when he talks
about power amps and negative feedback loops.
