●R30V 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. , this driving method that can adapt to load changes changes the driving method of the output signal in the past classic power amplifiers that simply obeyed the voltage or current of the input signal, so that the driving signal is upgraded to a controlled vector voltage related to the input signal and load impedance. And the vector current, the result is that the speaker system can obtain the full-frequency balanced driving energy and the cumulative spectrum attenuation characteristics with better hearing.

●New technical dimension of R30V amplifier:

The general design thinking of traditional high-power transistor amplifiers is to target a huge amount of reserve power to subdue extremely low-impedance loads, and hope to obtain good sound from this. From the results of decades of development, the goals and results are basically consistent. A different interpretation. The design of the vector power amplifier focuses on the actual changes in the impedance and phase of the speaker, and aims to match the sound quality with listening aesthetics, and expands the technical thinking to a new dimension.

The design of the vector power amplifier enables the output stage of the power amplifier to have an active and active thrust, and makes the transient speed of the start and stop of the speaker cone closer to the music signal. Pickup voltage, accurately and stably restore the music scene.

Driven by the R30V, the phase-frequency relationship of the horn sound wave is stabilized, the energy-frequency relationship is correct, and the long-awaited low-frequency elasticity and rich details are also immediately visible.

●R30V's "Tone Accurate Matching" function:

The application of vector drive technology at the basic level of the product takes the universal impedance shape parameters of the electric speaker system as the target drive parameters to achieve a wide range of vector drive.

For a specific type of speaker, in order to accurately deal with the microscopic differences in the physical parameters of its vibration system, the more refined technical application in vector power amplifier products is the segmental refinement of the driving characteristics, which can be targeted for specific types of speakers. Precisely set the target driving parameters, so that the performance of the timbre can reach the optimal state of hearing. The R30V level is equipped with a segmented drive mode (jumper) setting function.
