The PMC-Amplifier (Para-Magnetic Current Amplifier) will handle high quality loudspeakers, without air disturbance/acoustic aliasing distortion that can be found in common transistor amplifiers.
This PMC-Amplifier is an amplitude - velocity converter device, which is the most important for handling the reactive loads of the loudspeakers.
PMC Amplifier is the solution for handling complex waveforms (music) into acoustic vibrations!
The usual heat-providing elements of amplifiers are not included in this one. Therefore, during it's operation it does not heat itself at all! The LizardWizard PMC-amplifier does not require a warm-up. As soon as it is turned on, it provides the same 100% sound quality, that it would provide after a few hours of continuous use.
When developing LizardWizard, it was not just the principle of simplicity that guided the developer to choose the coil-amplifier but also the additional advantage of using the dynamic speaker, which is also a coil. In order, to make the above so mystically mentioned principle understandable, we first have to take a look at the operation principle of common transistor amplifiers. Today's everyday solid state amplifiers are usually classified as voltage-generator amplifiers. Based on their operation principle they provide the multiplicity of the input voltage at the output. If possible, this 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 are mainly made for voltage linearity and ultralow output resistance which can mainly drive only resistor loads. If we look at old tube amplifiers, the situation is different. The tube works as a generator, once it is under high voltage. In order for it to operate a speaker, an output transformer is necessary. Here the level of strain does matter, as the resistance of the load needs to be precisely specified.
The Primary coil has very high impedance needed by the Valve amplifier, this explains the mid & high frequency gaining distortion, early cutoff frequency response, specially in high-watt big transformers. Even in this case the only thing that we are 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, this is what most people like to think of dynamic 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 (the output of our CD player) can not be reproduce perfectly by the speaker. This distortion can be caused by several factors, like the fact that the magnetic fields are not homogeneous, or mechanical impotency, or several other nuances. Naturally, the creators of the speakers try to minimize these distortions with many built-in devices. Based on what is mentioned above, it is easily deductible that during the development of the LizardWizard the aim was not the linearization of the current-frequency, that is measurable at the end-points of the amplifier, but optimisation of the entire system, which is the transfer of the changing-impedance strained amplifier! (note: as opposed to the concept of the LizardWizard, the usual solutions are busy with the optimisation 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 transformation.
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.)
This means that our speaker's electronic impedance 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 existence 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 all impedance "changes" will receive the same acoustic (not electric) output power level.
In loudspeakers: when serial parallel law exist (ideal 1:1) you won't get air disturbance (a bit like SWR in antenna physics). This does not exist when the electric impedance is in mismatch mode (drive/load).
Example: Conventional amplifiers are mismatch 4 to 1 (4:1), because they have Voltage follower output so you receive 4 times bigger power output in parallel mode. In practice we found the most effective setting to be (1:1.2) slope where 1.2 (about +2dB) bigger output is in serial mode.
(parallel to serial-factor)
Our PMC amplifier will vary its gain and phase characteristic, this depends on the load nature (meanwhile in time), not like the standard fixed gain voltage following output type found in conventional amplifiers.
