Write your reply.

assistant: What? Damping factor *increases* with lower impedance? How is that?
I have never seen anyone claim that; in fact, quite the opposite.
I am aware that lower impedances will allow better power transfer,
but in my experience, the "damping factor" falls off, rather than
increasing with lower impedances. Most amp manufacturers state in
the spec sheets that "damping factor" is best at 8 Ohms, and gets
progressively worse with lower impedances. Most interesting!
Take care, and nice to see the "car audio" ousted!

Write your reply.

assistant: "Hiss" generally refers to high-frequency background noise.  "Hum" is
generally used to describe low-freq noise.  With turntables it's
called "rumble", but that's due to mechanical vibrations.  HPF's
(High-Pass Filters) are used to remove unwanted hum, in amp
circuits, for example.
Headroom is defined as the region between the maximum recording level
specified by the manufacturer of the equipment, and the amplitude at
which tape overload occurs.  It's specified in dB.  As you can
surmise, the greater the dB headroom, the better.
Saturation, in this case, is the point beyond a magnetic material's
ability to handle any additional flux.  Distortion occurs.  Very poor
fidelity results.
The bias applied to a tape head is an ultrasonic signal fed along
with the music information to keep the oxide magnetization within
the linear portion of its hysteresis curve.  The various tape types
are manufactured for optimum linear recording characteristics which
correspond to the recorder's bias setup.  Which is why you need to
use Hi-Bias tape if you're recording in Hi-Bias mode, Metal tape if
you're recording in Metal mode, etc.  Most tape decks are are
designed to automatically switch to the proper bias levels to
match a given tape.

Write your reply.

assistant: It Shouldn't really matter what it says through the multimeter... The
position of the voice coil will change the resistance of the circuit.
Therefore the best way to tell is that if the amplifier or whatever it was
that wants no lower than 6 ohms, then what you should do is go by the RATING
on the speaker.  If it is rated at 8 ohms.. then use it by all means... if
four ohms, then don't.  If you can't find it, then look on the spec sheet or
call the manufacturer.  Oh, one other thing... If it is 8 ohms... hook it up
by  itself or in series with another speaker.... Hooking two 8 ohms in
parallel would cause a drop to 4 ohms and therefore would wrek whatever if
was not supposed to be lower than 6...  The ratings is what you have to go
by.  The multimeter test doesn't prove a heck of a lot.

Write your reply.

assistant: Actually, that is untrue.... NEVER drop below the rated impedence of an
amplifier...  It may go good for a bit... But if it says like (2 ohms stable)
then that is the limmit you should be listening too.  If it is 6... Don't go
below it.  You'll never be able to turn it up loud like that because too much
current would be flowing through the amplifier because of the low resistance.
It is not a good idea to go lower than 6 ohms....  I would not do it.  It
shouldn't hurt the speakers at all unless when the amp blew up becasue of too
much current it make bad sounds which damaged the drivers.  Anyways... I'll
tell you now...  It is not a good idea to use 4 ohm speakers with that amp.
You'll be sure to wreck your amp if not right away.  Soon.

That's because it's recorded the same way.  If you play with the pitch
control on a tape deck while recording, then adjust the pitch control exactly
the same way on playback, there's be no audible change in playback.

Can't help ya with the Dolby S.  My deck is an AIWA ADF-990.  Still
records a mean signal on any brand of tape too, well... except for
Ferri-chrome..., but that stuff didn't last long. :-)
EQ stands for EQualization.  Referrs to the sound shaping to reduce
noise inherent in tape recording, but is NOT dynamically altered like
noise reduction circuits alter the frequency response.
Then something isn't working right.  If you record at a moderate level,
with say metal tape, there should be almost NO difference between tape
and source except for additonal noise.  If lower recording levels sound
fine, but starts to "flatten" (to use your terminology) at higher record
levels, then either the tape or your machine or both are not up to the
task you are employing them for.  Try premium tapes of Type I (normal),
Type II (Chrome or Chrome equivilent) and Type IV (Metal) and see which
one provides the best overall result.  Note that if a type I can record
at a higher level and cleanly, than say a type II, then often the type I
will be a better buy.  Keep in mind where the tapes are stored though.
Tyoe I erases more easily.  Metal are the most resistant to print
through and magnetic field erasure.

Write your reply.

assistant: And so it came to pass, on 08-14-96 09:36,
   that Herry Budiutama spake unto Matt Ion:
"Hiss" is, by definition, high-frequency noise.  If it was low-frequency, it
would be "rumble" or some other phenomenon.  Hiss is a phenomenon particular
to analog tape recording; it would take too long to really explain, but
suffice to say, low-frequency tape noise is not generally a problem.
Every tape has a limit to how strong a signal can be recorded to it.
Generally, a tape's noise floor will be at a certain minimum, and the hotter
you can get the audio signal to tape, the higher it will be above the noise.
"Headroom" is the amount by which you can safely exceed the optimum signal
level on peaks.
If the signal you're recording is typically quiet, you'd normally want to
boost the record level quite a bit; however, if it contains some very strong
peaks, they can saturate the tape, causing distortion.  If you don't have
enough headroom, you'd need to turn down overall level to bring the peaks
under control, but at the expense of bringing the normal signal closer to the
noise floor.
It's the same idea as clipping an amp -- saturation is the point at which the
tape can accept no more signal.  Distortion is the result.
That takes a little more explaining, which I don't have time for at the
moment.  Briefly, it's a high-frequency (44kHz-88kHz) signal that's added to
the record signal to boost the overall level to overcome a certain anomaly
that affects all magnetic recording at low levels (being an AC voltage, the
audio signal does cross through a low-level zone every cycle).
There are some good books you can check out that go into detail.  The only
one that comes immediately to mind is Audio Recording Techniques by David
Myles Huber...
