Design and Build

The FLS4 showcases meticulous craftsmanship with its ultra-high-grade, bespoke aluminum cast chassis. After CNC finishing, every part undergoes hand mirror polishing, with critical areas receiving additional hand-finishing through shot peening and anodization. This attention to detail culminates in an elegant silk-screened finish, reflecting Audia Flight's commitment to both aesthetics and durability. The robust construction not only enhances the amplifier's visual appeal but also contributes to its superior performance by minimizing vibrations and ensuring stability.

Performance

Designed for sonic excellence, the FLS4 delivers a frequency response from 0.3 Hz to 0.7 MHz (-3 dB), capturing a wide audio spectrum with clarity. With a total harmonic distortion (THD) of less than 0.05% and a signal-to-noise ratio (S/N) of 110 dB, the amplifier ensures a clean and distortion-free sound output. The impressive slew-rate of over 160 V/µs allows the FLS4 to handle rapid signal changes seamlessly, maintaining the integrity of dynamic music passages. Whether powering demanding speakers or driving multiple speaker configurations, the FLS4 provides consistent and reliable performance for an enhanced listening experience.

Technology

At the heart of the FLS4 lies Audia Flight's advanced technology, focused on delivering superior sound quality and reliability. The amplifier features fully balanced circuitry with highly selected components and 32 high-grade power devices. Its exclusive gain stage employs class A current-feedback circuitry, housed within an aluminum enclosure and encapsulated in epoxy resin to isolate it from interference and ensure thermal stability. The main power supply is built with sixteen 18,000µF 50V low-impedance capacitors, supported by two super high-current power supplies per channel and four stabilized independent stages per channel. This robust power architecture, combined with a 2000VA toroidal audio transformer enclosed within ferromagnetic shields and epoxy resin, guarantees clean power delivery without the need for fuses, relying instead on a microprocessor-controlled current sensor for protection.

Versatility and Compatibility

The FLS4 is designed to integrate effortlessly with a wide range of audio systems. It offers multiple input and output options, including unbalanced (RCA) and balanced (XLR) connections, ensuring compatibility with turntables, CD players, DACs, and other audio sources. Users can activate or deactivate inputs and adjust gain settings by ±6 dB to tailor the amplifier to their specific equipment and listening preferences. Additionally, the plug-and-play optional modules allow for easy expansion, enabling the FLS4 to adapt to evolving audio setups without extensive modifications.
