Design and Build

The FLS1 features a sleek brushed aluminum chassis that combines durability with a modern aesthetic featuring an engraved "Audia Flight" logo on the top cover, while the brushed and anodized aluminum remote control complements the unit's sophisticated look. The clear OLED blue display ensures easy navigation and operation. Internally, the preamplifier is powered by three toroidal transformers enclosed within a metal shield, providing low-noise power supplies that maintain the integrity of the audio signal.

Performance

The FLS1 offers a frequency response ranging from 0.3 Hz to 500 KHz (-3 dB), ensuring a wide audio spectrum is accurately reproduced. With a total harmonic distortion (THD) of less than 0.05% and a signal-to-noise ratio of 110 dB, the preamp delivers a clean and clear listening experience. The high slew-rate of over 100 V/µs allows the preamp to respond quickly to changes in music dynamics. Whether streaming high-resolution files or driving headphones, the FLS1 maintains precise control and high current delivery.

Technology

At the core of the FLS1 is Audia Flight's advanced headphone amplification technology, providing relaxed music listening through precise control. The fully balanced design minimizes interference and crosstalk between channels, maintaining signal purity. The high-end volume control, combined with dual mono circuitry, offers accurate adjustments. Optional modules expand the capabilities of the FLS1, allowing integration with MM/MC cartridges, additional analog inputs, and high-resolution digital sources with galvanic isolation to prevent electrical interference.

Versatility and Compatibility

The FLS1 integrates with a variety of audio systems. It features multiple input and output options, including unbalanced (RCA) and balanced (XLR) connections, ensuring compatibility with turntables, CD players, DACs, and other audio sources. Inputs can be activated or deactivated, and gain settings adjusted by ±6 dB to match specific equipment and user preferences. The plug-and-play optional modules enable easy expansion, making the FLS1 adaptable to evolving audio setups.
