Yamaha started as a musical instrument manufacturer in 1887.Yamaha started as a manufacturer of musical instruments in 1887, and established an audio division in 1967, and from the beginning, they also produced their own excellent amplifiers.In particular, the CA-1000 series received high acclaim and established a brand image in the field of pre-main amplifiers.Later, by utilizing the technology of the CA-1000 series and separate amplifiers, the CA-S1, CA-R1, CA-G1, CA-Z1, CA-A1, etc. were developed.The core models in the CA-1000 series were the CA-S1, CA-R1, CA-G1, CA-Z1, CA-A1, and CA-A1 series. The CA-R1 was the core of these models. The equalizer circuit was composed of a current mirror differential input using super low-noise pair FETs developed by Yamaha ? Darlington-connected emitter grounded amplification ? pureThe equalizer circuit consisted of a current mirror differential input using super low-noise pair FETs developed by Yamaha, Darlington-connected emitter grounded amplification, and a pure complementary SEPP output stage.The dual FETs for the differential amplifier in the first stage were developed by Yamaha as dedicated FETs for audio low-noise amplifiers.Compared to the multi-use FETs used in various electronic circuits, the dual FETs had a large gm, good pair characteristics, and low noise.The FETs had superior characteristics compared to the multi-use FETs used in various electronic circuits, such as high gm, good pair characteristics and low noise. By adopting a differential input stage using these FETs, direct coupling without a capacitor on the input side (i.e., no capacitor on the IC) was achieved.The differential input stage using these FETs eliminated capacitors on the input side, resulting in a direct-coupling (=ICL: input capacitor-less) configuration. The current mirror circuit also provides sufficient gain.The current mirror circuit provided sufficient gain and functioned as a kind of push-pull circuit, keeping harmonic distortion at a low level.
