SMSL VMV A1 PRO
Advanced GaN Technology for Superior Sound
At the heart of the A1 PRO lies next-generation GaN power transistors, sourced from Infineon Germany. These transistors operate at switching frequencies up to 1MHz—far beyond conventional silicon-based Class D amplifiers—reducing dead time from 35ns to just 15ns. The result: ultra-clean signal transmission, lightning-fast response, and dramatically reduced distortion, enabling a more detailed, lifelike listening experience.
High-Fidelity Performance with Ultra-Low Distortion
With an incredibly low Total Harmonic Distortion (THD+N) of just 0.003% and a high Signal-to-Noise Ratio (SNR) of 109dB, the A1 PRO ensures your music remains pure and transparent. Its wide frequency response and dynamic range of 111dB make it the perfect partner for high-resolution audio sources, faithfully reproducing every nuance and subtlety in your music.
Flexible Power Modes and Connectivity
The A1 PRO is designed to adapt to your setup. In stereo mode, it delivers 160W x2 into 4Ω and 85W x2 into 8Ω—ideal for most speakers. For more demanding setups, switch to mono BTL mode via XLR inputs and unleash up to 400W into 4Ω or 250W into 8Ω. Whether you’re powering bookshelf speakers or full-range floorstanders, the A1 PRO offers all the muscle you need with grace and control.
Premium Components for Audiophile-Grade Sound
Built with top-tier audiophile components, the A1 PRO features the renowned Texas Instruments PGA2311 volume control chip, ensuring smooth and precise volume adjustments with minimal distortion. Gold-plated connectors enhance signal integrity and long-term reliability, showcasing SMSL’s commitment to quality and performance.
Intelligent Design with Advanced Protection
Encased in a beautifully machined aluminum chassis, the A1 PRO combines durability with elegance. Its internal switched-mode power supply is specially optimized for high-performance audio, delivering clean power with minimal noise. Built-in protection circuitry guards against overheating and overcurrent, ensuring stable and reliable operation even under heavy load.
