One thing that just occurred to me about equalizers:

The equilizer that comes complete with a frequency analyzer may not always be
accurate, because it does not account for hearing deficiencies.   I   suspect
that many people have hearing that deviates several db from  being  flat over
20-20,000Hz.  Thus, when the analyzer indicates a flat response, you may  not
be HEARING a flat response.  The literature that I have on the Soundcraftsmen
equalizer says that it come with a special test record that you play and  use
to adjust your equalizer.  It claims that using your ear and the record,  you
can adjust the equalizer to give a response that is better than +/- 2db. This
will include any hearing problems that the person may have.

I do not know how well this test record works, since I  haven't  bought   the
equalizer yet, but once I found out I will post to the net if anyone is  in-
terested.
