Design Ideologies
Pathis’ InPoL Remix MkII is a fully-balanced pure Class A integrated amplifier using the latest generation double-InPol circuitry. The digital bias / gain set technology with intelligent control is entrusted to the same microprocessor which regulates the volume, thus guaranteeing the performance of the amplifier itself and its ability to drive the loudspeakers efficiently. Thanks to the optional HiDac Mk2 converter, music lovers who want the best from their digital sources will find their demands fully met.
Sonic Personality
InPoL (Inseguitore Pompa Lineare – Linear Pump Follower) is a system patented by Pathos Acoustics which has enjoyed great success and won many awards. Inpol devices have a special sonic personality obtainable only by means of this particular circuit design – fully balanced in Class A using a single solid state component in follower configuration, with high current gain and with voltage gain together. The valve amplifier amplifies the input signal voltage and InPoL supplies the current to drive the loudspeakers without any further amplification. In this way the signal is entrusted to the valves and becomes a true copy of the original, with all the quality, purity and harmonic content of the original.
This technology allows an increase in the theoretical output in pure Class A of between 25% and 50% together with a low output impedance which is fundamental for the damping factor, and further improved by the double InPol.
Ellegant Appearance
The elegant appearance design inherited from the ClassicRemix, with its compact dimensions make this a piece of audio equipment unique in its class. The central part of the chassis is carefully finished, while the lateral heatsinks, shaped to form the maker`s logo, make a strikingly attractive statement and serve to highlight the carefully protected valves placed in the centre of the chassis.
The Remix MkII is available in various colours and personal choices of finish. Remix MKII raises the musical listening experience to the highest level, thanks to Pathos’ audio design and engineering, and the use of components of the highest quality.
Going Digital
Thanks to the optional HiDac Mk2 board, your Remix MkII will be able to receive all your music from your PC by USB or from a digital source by S/PDIF.
Exploring InPoL – Pathos’ Patented Technology
The early theory influencing the whole InPoL project comes out to avoid any kind of general output-input back-feedback. It is claimed that, despite a fine developed back-feedback implies important benefits; it is considered always something artificial. This influences the sonic outcome and causes a loss of naturalness and spikiness. A good project not including the use of back-feedback implies on the other hand a higher rate of conversion and a slightly poorer damping factor, to put up with naturalness and harmony of the actual signal.
InPoL was born from this design theory. Developing a power stage without any back-feedback, featuring a limited distortion and a satisfactory damping factor. For this purpose it has been used a single solid-state component in follower configuration, with hypothetical voltage gain = 1 and with high current gain. Polarization is in pure Class A to avoid crossover distortions, typical of Class AB stages. Only solid-state NPNs are used, which are totally different from PNP ones; this difference could only be solved by back feedback. InPoL makes use of a big inducer as energy supply, which is driven by a transistor as a controlled current generator. In so doing the theoretical efficiency is doubled from 25 % to 50 % and low impedance is achieved, necessary to get a correct damping factor.
InPoL features an amplification factor of 1 when current is provided, so it copies the signal received from the input, without changing the harmonic content and keeping the signal naturalness unchanged. The only task of InPoL is therefore supplying the necessary current for driving the loudspeakers perfectly. InPoL is a worldwide patent.
