• Adopt independent dual-channel balanced transmission amplifier structure, effectively eliminate dynamic crosstalk interference problems;

• The audio signal input circuit is composed of field effect transistors for cascode differential amplification, and famous transistors for differential voltage amplification;

• The final stage is composed of 24 high-power transistors to form a powerful power output stage, which can easily drive speakers with an impedance as low as 2 ohms;

• The power supply part is composed of a 1500W toroidal transformer and a 120,000 microfarad audio special electrolytic capacitor;

• Class A output within 20W, automatically switch to Class A and B output when it exceeds 20W;

• Added balanced and unbalanced signal input options, and can connect two preamplifiers with different tones;

• The output state of Class A or Class A and B can be set, which is convenient for fine-tuning the tone and can also save power consumption and greatly reduce the heat of the chassis.

• The blue LOGO luminous font is added to the panel, which has a very high fashion and ornamental performance.
