Easily push many large speakers

The audio signal input stage uses ECC88/6DJ8 vacuum tubes for differential voltage amplification, famous transistors for second-stage differential voltage amplification, and the final stage consists of 24 high-power transistors to form a powerful power output stage, which can easily drive large speakers with impedance as low as 2 ohms.

Class A or Class A and B output status can be set

The output state of Class A or Class A and B can be set, which not only facilitates the adjustment of timbre, but also can choose to save power consumption to greatly reduce the heat of the chassis, so that the appropriate working mode can be selected when listening to different music contents.

Dynamic Class A circuit saves energy

Within 100W, it is a class A output state, and the tone is delicate and thick. When it exceeds 100W, it will automatically switch to Class A and B output mode, which makes it powerful when playing large dynamic music software.

Clear observation of output power status

The panel is equipped with an output power indicator, which enables users to instantly observe the power output value of the machine, which is very fashionable, dynamic and ornamental.

Better audio signal transmission

The balanced signal input terminal is made of NEUTRIKP products from Switzerland. The unbalanced signal input terminal and speaker connection terminal are all made of German WBT gold-plated terminal products. The internal audio signal connection line adopts the advanced wire of Jinbao brand imported from the United States, so that the audio signal can be transmitted more ideally.
