Rega Aura of Great Britain(Reiki)Reference-grade moving coil phono amplifier, the body is composed of low-resonance aluminum alloy plates, two-stage gain design, load capacitance and resistance each provide 5 different values ??for use, and it is also equipped with silent, mono/ The stereo switching function is not only the best partner for the same dynamic cartridge cartridge, but also with other high-quality dynamic cartridge cartridges to perform on the same stage.

The key amplifier parts are pre-selected and matched ultra-low noise FET field effect transistors to ensure that there will be no bias current feedback to the phono coil, which will affect the normality of the entire power supply system. Operation. Following the primary amplifier group, it is the high-frequency correction section of the RIAA equalization circuit composed of 1% ultra-low error polypropylene capacitors. As for the secondary amplifier group that is composed of a common base differential amplifier and handles the low frequency domain of the RIAA equalization circuit at the same time, it also adopts a fully symmetrical pure class A design. The main purpose of the third-stage amplification is to convert the signal into a balanced output so as to meet the connection needs of different equipment.
This is the current reference dynamic phono amplifier of Rega in the United Kingdom. Aura''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s fully symmetrical power supply has reserved 60% more energy reserves to further strengthen the overall stability. The parts used include a high-speed rectifier, a low-noise voltage reference tube, and a secret electrolytic capacitor with the word Rega printed on the body. Each level of analog amplification has its own independent decoupling package and LED reference current generation circuit, which gives full play to the extraordinary strength of the analog amplification circuit.
