SMSL PA-X Stereo / Mono Amplifier Infineon GaN 2x250W 4 Ohm / 1x500W 8 Ohm

The SMSL PA-X is an innovative amplifier that uses Gallium Nitride (GaN) transistors to offer 2x250W amplification at 4Ω. Its versatility also enables it to operate in pure mono mode, delivering an impressive 500W into 8Ω.

SMSL PA-X: Transistor GaN FET
The PA-X uses GaN FET transistors for its amplifier stage. These transistors offer significantly higher efficiency than conventional silicon transistors, minimizing energy losses during switching and reducing heat generation. In addition, GaN transistors are distinguished by their extremely high switching speed, of the order of 1MHz. This increased speed has several notable advantages: it eliminates switching noise in circuits, considerably reducing background noise, and it enables a much faster response time, instantly adapting to variations in power demand for greatly improved audio dynamics.

SMSL PA-X: Optimised switched-mode power supply
Le PA-X intègre un étage d'alimentation à découplage spécialement conçu pour une utilisation audio exigeante. Cette alimentation est capable de fournir une puissance considérable tout en maintenant un fonctionnement parfaitement silencieux. Pour une sécurité accrue, le PA-X est équipé de circuits de protection contre la surchauffe et la suralimentation.


SMSL PA-X : Gold-plated outputs
Les connecteurs de sortie du PA-X sont plaqués or afin de les protéger efficacement contre l'oxydation et la corrosion, tout en assurant une excellente conductivité électrique pour une transmission du signal audio optimale et sans perte.
