FLS1 Stereo

Experience audio excellence with the FLS1 Stereo, a full-balanced preamplifier with built-in headphone amplifier for immersive sound quality.

The FLS1 preamplifier reigns supreme in its category, excelling in speed, driving capacity, and precise control.

Discover the pinnacle of headphone audio with our Headphone Power Amplifier, harnessing Audia Flight’s cutting-edge technology to provide your headphones with a perfect and immersive musical journey, delivering an impressive 12Wrms at 8 ohms for precise control and ample current, and offering the convenience of two selectable gain levels.

Tailor your listening experience with the choice of two distinct gain levels. The FLS1 distinguishes itself as a complete balanced preamplifier, employing a high-end dual-mono volume control setup where each channel resides on its independent printed board. It offers an array of connectivity options, including XLR and RCA outputs, a REC RCA output at a fixed level, three RCA inputs, and two XLR inputs. Powering the FLS1 are three toroidal transformers, enclosed within a secure metal shield and bolstered by ultra-low-noise power supplies for pristine audio delivery.

Activate or deactivate inputs, adjust gain (+/- 6dB), and rename inputs as needed.

The FLS1 excels at delivering precise, high-speed musical signals to your amplifier, featuring a full brushed aluminum chassis, engraved “Audia Flight” logo, anodized aluminum remote control, OLED blue display, and plug-and-play support for two optional cards.
