[net.audio] More on EQ

rfg@hound.UUCP (08/25/83)

If you are the type of audiophile that can only stand to listen
to 'a straight wire with gain' (and then only if its 'monster
wire') forget EQ. Anything in the path adds noise and even the
slightest tweak of a control will produce audible changes.
However, if you are like 99.999 per cent of audiophiles, you
will probably Value your EQ next to your, say, MC cartridge.
True, on most of your audiophile program sources you will leave it
patched out most of the time (unless you have committed the un-
pardonable sin of having less than perfect loudspeakers in a 
perfect room). But, if you, like most of us, have a few (hundred)
imperfect sources (like older records-or cheaper records) you will
love tinkering up the sound to more modern standards.
Combining a spectrum 'lyzer with your EQ is about the best idea since
sliced bread. Not only does it give you (via microphone) an instant
picture of the realistic response of your system (assuming pink noise
input, of course) but it is an amazingly effective trouble shooting
tool for those of you so inclined. I have found it (with noise
source) much more useful than an oscilloscope. And also more fun
to watch just for the hell of it. You will learn about the spectral
distribution of sound which is at least interesting and could
be useful.
The C-101, previously described, has all the required goodies (mike,
noise source,RTA,EQ). I also have one and use it 101 % of the time.
It is far from perfect. To be fair, here are some negatives. The
instruction book is "cutesey" and not that informative. The range
(amount) of EQ is less than some. I have encountered oscillation
at times in the highest band (probably only proof of a fault in
my unit). The front panel labeling is barely legible - sort of
a black-on-black effect. Also, to be fair, I, of my own experience, know of
none better (altho such there may well be) and I have seen it
advertised for under $300.      -Dick Grantges vpoo
