Audia Flight - FLS4 - Power Amplifier

The Audia Flight FLS4 Stereo Power Amplifier represents the pinnacle of precision engineering and an unwavering commitment to sonic excellence. It's more than just an amplifier; it's an audio masterpiece. Here's a detailed and refined description:

FLS4 Stereo Power Amplifier: Where Precision Meets Sonic Excellence

At Audia Flight, we believe that crafting the perfect stereo power amplifier is both a science and an art. The FLS4 Stereo Power Amplifier is the result of our tireless pursuit of perfection in audio reproduction. With a breathtaking response speed boasting an impressive bandwidth of over 0.7MHz, substantial power output reaching up to a formidable 700 Watts, and the remarkable ability to exert precise control over even the most demanding speakers, the FLS4 is the embodiment of sonic excellence.

A Symphony of Engineering and Human Sensibility

The creation of the FLS4 involved not just cutting-edge technology but also the discerning ears of experienced audiophiles. We understand that true audio perfection is achieved through the harmonious blend of scientific precision and the human element. Our engineers painstakingly crafted the FLS4, making small yet critical adjustments, such as resistor and capacitor values, based on what they heard. This approach mirrors the dedication of a master luthier who refines an instrument to achieve the perfect tonal character and emotional resonance.

Masterful Craftsmanship: The Heart of Italian Design

Much like a fine Italian sports car, the FLS4 starts with a chassis of ultra-high-grade bespoke aluminum. After undergoing meticulous CNC finishing, each component is subjected to careful inspection and painstaking hand-polishing. Critical areas receive additional hand-finishing, which, when combined with shot peening and anodization, results in a visually stunning piece of engineering art. The finishing touch is an elegant silk-screening process that reflects the precision and attention to detail that defines the FLS4.

Excellence Runs in the Family

The FLS4 shares its lineage with the esteemed Strumento Series, inheriting a legacy of excellence. Inside, you'll find fully balanced circuitry, a curated selection of premium components, and a robust ensemble of 32 high-grade power devices. The power supply is a marvel in itself, featuring low impedance capacitors with an impressive 288,000µF capacitance dedicated to the main power supplies.

The Art of Amplification: A Gain Stage Like No Other

At the heart of the FLS4 lies its exclusive gain stage, an Audia Flight masterpiece crafted around a class A current-feedback circuitry. To ensure total isolation from external interference and provide thermal stability for its discrete components, the gain stage is elegantly enclosed within an aluminum chamber and encased in epoxy resin. This meticulous approach ensures the purity of the audio signal.

Power Supply: The Backbone of Performance

The FLS4's power supply is a testament to engineering prowess, boasting 16 low impedance capacitors rated at 18,000µF and 50V. It consists of two super-high-current power supplies per channel and four stabilized independent stages for each channel, including two for the input stages and two for the Audia Flight current feedback stage.

Uncompromising Purity: No Fuses, Just Precision

In adherence to our uncompromising philosophy of sound purity, the main power supply for the output stage is devoid of fuses. Instead, a current sensor, read by a microprocessor, ensures precise power delivery without any detrimental impact on sound quality.

A Masterpiece in Metal and Sound

Every detail, both in circuitry and mechanics, has been meticulously addressed. When the FLS4 sits on your audio shelf, its power transformers, situated on an independent chassis, are meticulously decoupled from the audio circuit chassis, efficiently grounding any residual vibrations from the transformers.

Experience the Art of Sound

The Audia Flight FLS4 Stereo Power Amplifier is more than just an amplifier; it's an artful expression of our passion for audio perfection. Like its sibling, the Strumento N°4 mk2 Stereo Power Amplifier, it is designed not merely to reproduce music but to elevate your entire audio system to a realm of perfection you might have thought unattainable. It's time to experience the true power of music with the FLS4 Stereo Power Amplifier.
