The PMC-Amplifier (PMC means Para-Magnetic Current) handles High Quality
loudspeakers superior, without the everyday type
amplifiers air disturbance (acoustic aliasing distortion).
This PMC-Amplifier is an amplitude to velocity
converter device, that is the most important
for the reactive loads (loudspeakers are).
PMC Amplifier is the solution for handling correctly the complexitive waveforms (music) into acoustic vibrations!
The usual heat-providing elements of amplifiers are not included in this one.
Therefore during its operation it does not heat itself at all.
LizardWizard PMC-amplifier does not require a warm-up at all.
As soon as it is turned on, it provides the 100% sound quality,
as what it operates with after a few hours of straight use.
When developing LizardWizard, it was not just the principle of
simplicity that guided the developer to choose the coil-amplifier.
The key of the additional advantages in this case was the dynamic speaker,
which is also a coil. And what a coil it is?!
In order, to make the above so mystically mentioned principle understandable,
first we have to take a look at the operation principle of the usual amplifiers.
Today's everyday solid state amplifiers are usually classified as voltage-generators.
Based on their operation principle they provide the multiplicity of the input voltage
at the output ending. If possible, that occurs independently of the strain of the output.
The strain of the output, or rather of the end-transistors and the power-supply can be loaded variably,
it won't change the output current at all. Therefore the output is stable.
All conventional "solid state" amplifiers are false in
acoustic physics, they made for voltage linearity and ultralow output
resistance which can drive ideally only resistor loads.
If we look at the old tube amplifiers, the situation is different there.
The tube works as a generator, once it is under high voltage.
In order for that to operate a speaker, an output transformer is necessary.
Here the level of the strain does matter, the resistance of the load needs to precisely specified.
The Primary coil had very high impedance needed by the Valve, this is explaining the mid & high frequency gaining distorsion, early cutoff frequency response, specially in high-watt big transformers. Even in this case the only thing what we’re talking about is just a simple impedancy.
One of the bad qualities of the dynamic speaker is that the coil that moves in
a magnetic field can be viewed as many things, except as a passive unit with constant parameters.
However, that is what people like to think of speakers in general.
If we also count that the speaker is an impedancy that can be strained in a complex way,
then we have to accept that the strain in relation to the original sound
(that is the output of our CD player) the speaker is incapable to follow perfectly.
This distortion is caused by several factors, like the fact that the magnetic fields
are not homogeneous, or the mechanical impotency, or several other nuances.
Naturally, the creators of the speakers try to minimize these distortions
with as many devices, as possible.
Based on the above mentioned, it is easily deductible that during the development
of the LizardWizard the aim was not he linearization of the current-frequency,
that is measurable at the end-points of the amplifier, but optimalisation
of the entire system, which is the transfer of the changing-impedance strained amplifier.
(As a note: as opposed to the concept of the LizardWizard,
the usual solutions are busy with the optimalisation of the independent units,
rather than the entire system.)
Previously we have just talked about the complexity of the speaker.
However, until now we have considered the load as a passive bi-polar,
that is under current, therefore it makes a sound. What's important here
is that it DOES make a sound!
Electronically the bipolarity is the speaker itself,
but physically it is quadropolar, although the second pair of poles are
not electronic, but sonic. What we're talking about here is an electronic transformator.
That means that the electronic parameters of the speaker are changing according to the
factors of the environment, physical happenings of the sonic side.
(With an adequate solution the sonic features can be transformed into units of
electronic circuits, therefore the speakers are often modelled with and are stimulated
by complex electronic switches.)
That means that our speaker's electronic impedance well contains all
the sonic parameters of the blaster, the box itself, and even that of the surrounding environment too!
Because of the coil within the amplifier and because of the close electronic tie between the coils, this system can provide a faster and more precise operation than any other system supplied with the usual amplifiers.
PMC means the existance of the serial parallel law (unknown yet). Serial parallel law means:
Example: when you connect 2 loads (2 pieces of 8ohm loudspeakers) in serial or you connect it in parallel mode, you must get the same output volume, BUT acoustically, not electrically! When this happens means all impedance "changes" will receive the same acoustic (not electric) output power level.
In loudspeakers reality: when serial parallel law exist (ideal 1:1) you won't get air disturbance
(a bit like SWR in antenna physics).
Unexist when the electric impedance is in mismatch mode (drive/load).
Example: Convetional amplifiers are mismatch 4 to 1 (4:1), because
they have Voltage follower output so you recieve 4 times bigger
power output in parallel mode.
In practice we found the experimented good setting is
(1:1.2) slope where 1.2 (about +2dB) bigger output is in serial mode.
(parallel to serial-factor)
PMC amplifiers are specificly varies its gain and phase caracteristic, it depends of the load nature (meanwhile in time), not like the standard fixed gain voltage follower output type conventional amplifiers.
