[SE800] PFFB High Power Class-D Amplifier

High Power Output Class-D Amplifier with PFFB by SylphAudio.

300W at 8Ω
600W at 4Ω

Integrated housekeeping supplies, which enables wide supply voltage range and very low idle power dissipation.

PFFB reduces load dependency and improves noise and distortion. Perfect for high power, full-range sound system applications.

Optional clock and mute headers for multi-channel advanced projects.

Differential / Single-Ended input. Just short out (IN-) to GND for SE input.

Robust protection circuitry for exceptional reliability.

Elna Silmic II input coupling cap.
