Two Phono inputs are carried and the level adjustment up to -12dB and the four-point change of an input impedance are possible for one line of them.Įven -6dB is a transition of NFB and level adjustment serves as a transition of the output volume from -6dB to -12dB. Moreover, the tone-quality modification is aimed at by using the high precision element selected carefully for a using element. While an equalizer part carries the differential amplifier by the low-noise transistor which carried out the can shielding in the first rank and aims at a stabilization of the output middle point, and the improvement in an SN ratio, the distorted reduction and the improvement in stability are aimed at by applying the direct current NFB 100%.įurthermore, SEPP of the final stage could carry out the Class-A operation of the time of a large swing, and has taken out the high-output voltage by the low distortion. With features, performance, functions and high cost-performance, it overflowed with charm to steal the audiophiles heart: a power amp section with the world’s first Class A/B switchover that had a convenient switch that changed from low-distortion, priority-on-sound-quality class A operation to high-power class B operation, two huge 18,000 μF block aluminum electrolytic capacitors that blew away the competition, a phono equalizer boasting accuracy to within☐.2dB of the RIAA standard and a permissible MM input of 310mV, and a unique continuous loudness control. Of course the CA-1000 had more appeal than just its exterior. The seamlessly connected single-sheet aluminum front panel and a white wood cabinet (open-pore-finished prickly castor oil tree wood) modern style was created by the GK Design Group and its beauty was distinct from both the heavy wood grain style and the mechanical component style. This was the birth of the CA-1000, a classic representative Yamaha HiFi component that is still talked about today. Yamaha released the CA-700/500 and entered the component stereo market in 1972, and the next year began a completely different integrated amplifier lineup.
