●R20V vector drive technology

Vector drive is designed according to the impedance characteristics of the electric speaker system. It is a precise driving method of the power amplifier to the speaker system. It enables the amplifier to adaptively adjust the amplitude and phase of the voltage and current driving the speaker system according to the changes in the amplitude and phase of the speaker impedance. , so that the speaker system can obtain the full-frequency balanced drive energy and the cumulative spectrum attenuation characteristics with better hearing. For a specific type of speaker, in order to accurately deal with the microscopic differences in the physical parameters of its vibration system, the R20V is equipped with a segmented drive mode (jumper) setting function, which can precisely set the target for a specific type of speaker. Drive the parameters to make the natural expression of the sound to be close to the state of the music scene, and realize the "accurate sound matching" between the amplifier and the speaker.

●R20V balanced amplifier technology

In the fully balanced R20V power amplifier, the high-power rectifier circuit and the signal ground wire are well isolated. In the ordinary single-ended push-pull amplifier, the pulse ripple current of the rectifier circuit interferes with the music signal through the ground wire. In

R20V, it has been changed from is removed in principle.

●Invisible input signal conversion circuit of R20V

The input stage of the R20V adopts a well-designed Invisible "Escape" circuit. The extremely low noise Invisible input stage can convert the input unbalanced signal into a fully balanced signal required by the power amplifier through precise operation. and other functions. The music signal output by the Invisible input stage is highly faithful to the original input, and the impact on the timbre is far lower than the threshold of the human ear, providing a transparent and pure driving signal for the "vector drive" balanced post stage.

●R20V perfect safety protection system

Each channel of the high-power R20V is independently equipped with complete protection functions: Mute on startup and shutdown: No matter whether there is a music signal input or not, the startup and shutdown of the R20V is completely free from the current impact sound often found in simple designed amplifiers. Output DC detection: Quickly and sensitively sense unexpected DC output even within a safe range, and cut off the connection between the amplifier and the speaker in time. Short circuit and overload protection: Effectively protect the amplifier from damage due to occasional speaker cable short circuits. Ultra-audio signal protection: When the super-audio signal energy exceeds the safe carrying energy level of the conventional speaker tweeter, the connection between the amplifier and the speaker is quickly cut off.

●Performance of R20V amplifier: The maximum output power of R20V reaches 350W/8Ω, 700W/4Ω. Since the output of the vector power amplifier is a flexible thrust, it can always process each phrase and each note with the power potential energy several times that of the traditional amplifier, which is equivalent to the actual listening volume. Power thrust performance. The surging effective thrust is the physical basis for the transparent and open sound field
