Know before you buy
Yes, the FLS 9 is designed for demanding loads. It delivers 150 watts per channel at 8 ohms and scales up to 500 watts at 2 ohms, providing the current necessary to maintain control over complex speaker impedances.
The base unit does not include a DAC or phono stage. However, Audia Flight offers optional modules for both, allowing you to integrate these functions directly into the chassis if needed.
The fully balanced circuit architecture helps minimize noise and interference throughout the signal path. This results in a cleaner, more precise sound with a lower noise floor compared to standard unbalanced designs.
The volume control features a gain range of -90dB to +10dB with a fine resolution of 0.5dB. This allows for extremely granular adjustments so you can find the perfect listening level for any track.
No, the FLS 9 is not designed for rack mounting. Due to its significant weight of 25.5 kg and its dimensions, it is best placed on a sturdy, dedicated audio stand or shelf with adequate ventilation.
No, the FLS 9 is not bridgeable. It is intended to function as a high-performance stereo integrated amplifier rather than a mono-block configuration.
