Description g\u00e9n\u00e9rale et concept<\/h3>\n

Le pr\u00e9amplificateur Phasemation CM-2200 est le descendant direct du CM 2000, un pr\u00e9amplificateur hybride passif usant de composants finement s\u00e9lectionn\u00e9s et principe d’ajustement du volume novateur et b\u00e9n\u00e9ficiant d’un brevet. Comme le CM-2200, le CM-2000 permet de cumuler entr\u00e9es et sorties en sym\u00e9triques ou asym\u00e9triques. Avec cette s\u00e9rie de pr\u00e9amplificateurs : Phasemation a cr\u00e9\u00e9 des pr\u00e9amplificateurs passifs \u00e9quilibr\u00e9s et ultra-r\u00e9solvants sans pour autant sacrifier la densit\u00e9 sonore et l’\u00e9tagement des plans de la musique.<\/p>\n

Pour cette nouvelle it\u00e9ration, Phasemation \u00e0 compl\u00e8tement revu son transformateur d’att\u00e9nuation en permettant par le basculement d’un interrupteur de choisir entre 0dB ou + 6 dB de gain. Avec ce gain suppl\u00e9mentaire le pr\u00e9amplificateur Phasemation CM-2200 est \u00e0 m\u00eame driver aussi bien des syst\u00e8mes \u00e0 haut-rendements que des ensembles bas rendements.<\/p>\n

A ce jour le pr\u00e9amplificateur passif CM-2200 est le seul \u00e0 ce jour \u00e0 disposer de + 6 dB de gain.<\/p>\n<\/div>\n

\n

Nouveaut\u00e9s sur le CM-2200<\/h3>\n
\n

Added a gain changing switch (0\/+6db)<\/h4>\n

The balanced specification attenuator transformer winding developed for the CM-2000 has been revised to have a gain of +6dB, taking advantage of the fact that it is a transformer. In this model, a gain changing (0\/+6dB) switch has been added to the rear panel, and the variable range of the attenuator is 0dB (0dB to -70dB) or +6dB (+6 dB to -64dB) can be selected. The transformer winding structure has been re-examined to ensure wide-range frequency response and impedance characteristics regardless of which gain is selected so that the CM-2200’s high and clear sound image localization can be enjoyed at either gain.<\/p>\n<\/article>\n

Main features carried over from CM-2000<\/h3>\n
\n

Adoption of newly developed high-performance core materials and winding materials<\/h4>\n

We reviewed the 0.2 mm thick permalloy material that was used previously and newly developed an “extremely thin (0.1mm) super alloy material.” In addition, for the winding material, rather than the high pure copper wires that were used previously, we specially ordered PC triple C polyurethane wires which are optimal wires for audios. In combination with a large core shape, we reached an excellent characteristic of a high low\u2013pass linearity and a delicate and calm high frequency and achieved an expression of a vast space.<\/p>\n<\/article>\n

\n

Development of optimum winding specified for balance<\/h4>\n

We reviewed the attenuator transformer winding specifications from the beginning and developed an attenuator transformer for balancing in which two attenuator windings of the hot and cold sides of the balance connection are wound in one transformer. By utilizing the fact that there are two more attenuator windings, it is also possible to create a signal (at the cold side) inside the transformer for the unbalanced input and to support a complete balanced output. Also, a high common mode rejection ratio (CMRR) was also obtained with the two windings that support the balance.<\/p>\n

Since the transformer for a balanced sound volume adjustment circuit was composed with one CH1, excellent frequency characteristics and phase characteristics were actualized in a wide band, the phase distortion in the audible band was reduced and most important was that the freshness was high and a clear constant sound image was brought into effect.<\/p>\n<\/article>\n

\n

Eliminate external induction hums and unnecessary vibrations<\/h4>\n

For external induction hums, a chassis base with copper plating on a solid 2 mm thick steel plate and a case cover with an induction hum shield is arranged. In addition, the magnetic shield material located near the transformer has a double structure.<\/p>\n

The attenuator transformer is floated from the main unit with a high damping rubber material and it prevents external vibrations from propagating. The front panel adopts a 20 mm thick slanted aluminum panel that is equivalent to the control amplifier CA-1000. By adding a walnut material base under the exterior case, unnecessary vibration is effectively eliminated by combining different kinds of materials and brings about playback sounds with a good S\/N ratio.<\/p>\n<\/article>\n

\n

Use of high quality parts<\/h4>\n

We adopted rhodium plated terminals made by Furutech which are reputed for having high-quality and high sound quality on the input and output terminals.<\/p>\n

In addition, the foot adopts TAOC\u2019s high carbon cast iron insulators which contribute to increasing the resolution of the sounds.<\/p>\n<\/article>\n
