FLS4 Stereo Power Amplifier

The Audia Flight FLS4 Stereo Power Amplifier is a remarkable stereo power amplifier known for its exceptional speed (bandwidth over 0.7MHz), formidable power (up to 700 Watts), and exceptional control over a wide range of speakers.

FLS 4’s meticulous design process incorporates the discerning input of our trained listeners.

By channeling these efforts, we’ve crafted an amplifier that approaches our quest for sonic perfection, much like a luthier refines the tonal and emotional qualities of their instruments through years of craftsmanship and a discerning ear.

Just like its Strumento counterparts, the FLS4’s chassis originates as a high-grade aluminum cast. After precision CNC finishing, every part undergoes meticulous hand inspection, mirror polishing, manual refinement of crucial areas, and enhancement through shot peening and anodization. Finally, an elegant silk-screening process provides the finishing touch.

The FLS4 draws inspiration from the amplifiers in the Strumento Series.

The FLS4 incorporates a range of high-quality components, including a fully balanced circuitry and 32 high-grade power devices. Its power supply features low-impedance capacitors, with a substantial 288,000µF on the main power supplies. The amplifier’s gain stage is a unique Audia Flight design, employing a class

A current-feedback circuit enclosed within an aluminum housing and encapsulated in epoxy resin. Furthermore, the main power supply consists of 16 low-impedance capacitors and two high-current power supplies per channel, along with four independent stages for each channel.

As part of our philosophy, a 15VA toroidal transformer is dedicated to logic control and protection circuits, ensuring complete isolation from the audio circuit.

Much like the Strumento Series, the FLS 4 Stereo Power Amplifier embodies Audia Flight’s commitment to audio excellence. With 12 power supplies, premium circuit boards, and a 2000VA toroidal transformer enclosed in epoxy resin and ferromagnetic shielding, it avoids fuses in the main power supply to enhance sound quality.
