Know before you buy
With its massive 2000VA toroidal transformer and ability to deliver up to 700 watts into 2-ohm loads, the FLS 4 is designed to drive even the most demanding, low-impedance loudspeakers with ease. Its high current-feedback design ensures excellent control and grip over difficult woofer configurations.
The FLS 4 is a dedicated power amplifier and does not include an integrated volume control or source switching. You will need to pair it with a high-quality preamplifier or a digital source with a high-performance variable output to manage your system.
The Class A current-feedback gain stage is engineered for exceptional speed and transparency. This design choice allows the amplifier to react instantly to musical transients, resulting in a highly detailed, natural sound with superior signal integrity.
No, the FLS 4 is not bridgeable. It is designed as a high-performance stereo amplifier, and its internal architecture is optimized for two-channel operation without the compromises that often come with bridging circuitry.
The FLS 4 is a substantial piece of equipment weighing 34kg, so ensure your rack or stand is rated for this weight. Because it is a high-performance amplifier, it requires adequate ventilation space around the chassis to manage heat dissipation effectively.
Audia Flight removes fuses from the main power supply output to eliminate potential points of resistance and impedance that can restrict current flow. This design choice ensures the amplifier can deliver instantaneous power to your speakers without the bottlenecking effect that traditional fuses can introduce.
