FULL BALANCED STEREO PREAMPLIFIER WITH HEADPHONE AMPLIFIER

The FLS1 is a fully balanced preamplifier designed for uncompromising performance. Its high-end volume control operates in a true dual-mono configuration, with each channel built on a separate PCB to ensure optimal channel separation and signal integrity. It features XLR and RCA outputs, a fixed-level REC RCA output, three RCA inputs, and two XLR inputs. All inputs are user-configurable—individually activatable, gain-adjustable (±6 dB), and renameable for ease of integration and personalization.

Power is supplied by three toroidal transformers, enclosed within a metal shield to ensure ultra-low noise operation. At its heart lies Audia Flight’s exclusive Class A current-feedback gain stage, powered by four fully independent, stabilized stages per channel—two for the input stage and two for the output. The output stage, based on Class A-biased MOSFET devices, delivers high current with low noise, capable of effortlessly driving any power amplifier.

With a bandwidth exceeding 500 kHz, the FLS1 transmits musical signals with unmatched precision, energy, and speed. The robust, full brushed aluminum chassis features an engraved Audia Flight logo on the top panel, a crisp blue OLED display, and a matching anodized aluminum remote control—reflecting the amplifier’s high-end craftsmanship.

In addition to its outstanding preamplifier capabilities, the FLS1 includes a true headphone power amplifier based on Audia Flight technology, delivering a powerful 12 Watts RMS into 8 Ohms. This allows it to drive even the most demanding headphones with perfect control and effortless musicality. Two selectable gain settings ensure optimal performance across a wide range of headphone types.

For added flexibility, the FLS1 includes two plug-and-play slots for optional expansion cards, making system customization simple and future-ready.
