The design secret of pure class A’s excellent stability

Earlier, some netizens on the Internet ridiculed the audio system using pure class A power amplifiers, which are more suitable for winter heating, whether household or vehicle pure class A power amplifiers because of the huge heat generation, the heat dissipation performance design is very particular.

The heat of the internal circuit is directly brought up to the top of the heat sink and discharged outward, and the deep grille design increases the air diversion between the heat sinks, quickly bringing heat dissipation effect and ensuring sufficient stability in the cabin space.

Pure sound floor with extremely low distortion

The Duomo Plus cathedral amplifier adopts a two-channel symmetrical balance circuit design, and the internal is an independent single-channel power amplifier circuit on both sides to form a two-way pure class A power amplifier, and it is a pure post-stage power amplification design, so that the internal mutual interference sound coloring is minimized, and the crosstalk between the circuits is kept to a minimum state, bringing a pure clean sound floor effect. Screws, pure copper terminals, PCB circuits, including metal components of the fuselage are all customized by Sefiny, from power addition to signal conduction to achieve lossless transmission, reduce complex pre-circuit adjustment, audio signals in the entire amplification path can achieve signal straightforward, signal-to-noise ratio is high

Precise control at high power

At present, high-efficiency Class D digital power amplifiers sweep the market, and power outputs of more than 2-300W abound, but in terms of pure Class A power amplifiers, more than 100W power output is already fierce high power. For Sepaney, Duomo Plus was designed to cope with the many speakers on the market that require excellent sound quality and high power requirements
