Commentary
OMEGA series stereo power amplifier.
As a dual monaural design, the left and right channels are independent from the power cable, eliminating interference between the channels.
It can also be used as a high-power monaural power amplifier with bridge connection.
The amplifier circuit employs a first stage / pre-driver stage with a disclitoto configuration of J-FET and MOS-FET, and an output stage with 16 single-channel high-voltage / high-current bipolar power transistors.
The voltage supply to the input stage employs a discrete configuration and high-precision regulator module with a shield case, and a high-quality metalized polypropylene capacitor is used for the interstage device.
The power supply section is equipped with two 2,500 VA giant transformers and uses a large-capacity capacitor with a total capacity of over 100,000 μ F per channel.
The signal transmission cable uses a shielded litz wire with less skin effect.
