The SMSL PA400 is an innovative amplifier that uses Gallium Nitride (GaN) transistors to deliver 2x250W of amplification at 4Ω. Its versatility also allows it to operate in pure mono mode, where it delivers an impressive 500W at 8Ω. Every component in the PA400 is carefully selected to achieve exceptional audio performance, with extremely low harmonic distortion of 0.0003% and a signal-to-noise ratio of 115dB.
SMSL PA400: GaN transistor amplification
The PA400 uses GaN FET transistors in its amplification stage. These transistors offer significantly higher efficiency than traditional silicon transistors, which minimizes energy loss during switching and thus reduces heat generation. In addition, GaN transistors are characterized by an extremely high switching speed, on the order of 1MHz. This increased speed provides several significant advantages: it eliminates switching noise in the circuits, which significantly reduces background noise, and it enables much faster response times, so the amplifier can instantly adapt to variations in power demand and thus significantly improve audio dynamics.
SMSL PA400: Optimised power supply
The PA400 integrates a switching power supply stage that is specially designed for demanding audio applications. This power supply can deliver significant power while maintaining completely noise-free operation. For increased safety, the PA400 is equipped with both overheating and overpower protection circuits.
SMSL PA400: Gold-plated output connectors
The PA400's output connectors are gold-plated to effectively protect against oxidation and corrosion, while ensuring excellent electrical conductivity for optimal and lossless transmission of the audio signal.
