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.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cbr data-mce-fragment=\"1\"\u003eMain features carried over from CM-2000\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdoption of newly developed high-performance core materials and winding materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe 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.

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.\u003c\/p\u003e\n\u003cp\u003eSince 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.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEliminate external induction hums and unnecessary vibrations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor 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.
