Control amplifier which enriched the functionality for beginning advanced circuitry, and a detailed tone-quality serious consideration design being performed even to a material, and also making pleasure of a music play richer.
A basic circuit begins phone amplifier with the first rank of a super-low-noise FET difference input and the pure Class-A SEPP output stage which arranged the pair property strictly, considers all the included circuitries for MC head amplifier of a super-low-noise FET input as DC amplifier stream composition, and is improving the nakedness property.
Furthermore, the impedance of the feedback circuit was lowered thoroughly, the SN ratio has been improved, low-distortion-izing in the necessary minimum amount of NFB and low-noise-ization were attained by this, and the Low-TIM design which banishes an occurrence of the excessive dark blue unbalance distortion by too much NFB is attained.
The cartridge loading selector of a man month/MC independency is carried, MC can choose four positions, man month can choose the load resistance value of five positions, and all cartridges are supported.
In addition to Bass and Treble where a turnover frequency is switched by a low-pass two-step and the high region two-step and which can perform a control of ±10dB, respectively, the try tone control which carries a Mid control is carried by the right-and-left standalone version.
Furthermore, the Tape EQ switchpoint which leads this control signal to a sound-recording output is carried.
Two record selectors as which the sound-recording output of included 4 position can choose mutual dubbing are carried.
The oxygen-free-high-conductivity-copper line of a high purity is adopted as the shielding-wire fraction handling a small signal for the coaxial cable at all the other lead wire.
Furthermore, the TONE defeet switchpoint and flat amplifier it1 switchpoint which can attain simple-ization which the signal path put into practice are carried.
