PSD-650 is an independent two-channel balanced structure design, that is to say, each channel has a positive and negative phase amplification line, and two channels have four phase amplification lines; although the whole machine is only configured A power transformer, but it reaches 3000W, and the left and right channel power supplies are separated and finely divided into four separate AC power windings and bridge rectifiers, and used with up to 240,000μF capacity electrolytic capacitors to ensure In addition to the continuous power source of the whole machine, it also effectively reduces the dynamic crosstalk between the channels to a minimum.
The audio signal input circuit of PSD-650 consists of FET and bipolar transistor cascode differential amplification, two-stage differential voltage amplification and current drive for the famous class transistor, and the final amplifier stage consists of 48 high-power transistors. The PSD-650 has a huge 50W×2 (8Ω) Class A power and 550W×2 (8Ω), 1100W×2 (4Ω) Class A power output, which can drive most speakers on the market and can also be restored. A rich, delicate, flexible, and airy sound texture.
