From the overall design to the smallest detail, the craftsmanship of the D-Series reflects a commitment to quality and performance. Its expressiveness of sound quality inherits our usual style, and the stability tends to be perfect. The short circuit protection function of the D series can ensure that the engineer can protect the machine itself and the loudspeaker in the case of misoperation or other accidents. A nonlinear comparator is specially set up in the D series amplifier, and once the signal is found to be clipped, the working state of the power amplifier circuit can be adjusted immediately until the clipping is eliminated. The D-Series amplifiers have excellent signal conversion characteristics. It has very small harmonic distortion (THD), intermodulation distortion (SMPTE-IM), transient intermodulation distortion. Innocent, natural sound quality is the ultimate interpretation of music. Protects the speaker from noise caused by strong impulse currents.
