The Eversolo AMP-F8 is a high-performance Class AB stereo power amplifier engineered for low-noise signal reproduction and high-current loudspeaker control. Delivering 180W RMS per channel into 8 ohms and 280W RMS into 4 ohms in stereo mode - or up to 500W RMS into 8 ohms in bridged mono configuration - the AMP-F8 provides ample dynamic headroom for demanding floorstanding loudspeakers. The amplifier employs a dual differential input architecture with symmetrical circuitry and precision negative feedback, achieving a THD+N of 0.003%, a signal-to-noise ratio of ≥115 dB, and a damping factor exceeding 400 for rapid transient decay and bass control.

Built upon a custom 800W toroidal linear power supply with an integrated DC blocking circuit to eliminate mains DC offset and mechanical hum, the AMP-F8 incorporates an energy bank of 24 audio-grade filter capacitors. The output stage utilizes three pairs of precision-matched high-current power transistors per channel in parallel configuration for linear current distribution across varied impedance loads. Housed in a CNC-machined, sandblasted anodized aluminium chassis with real-time analogue VU meters, the unit includes balanced XLR and single-ended RCA inputs with selectable gain (23 dB / 29 dB) and 12V trigger connectivity.

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• High-Power Class AB Output Stage: Delivers 180W/ch @ 8Ω, 280W/ch @ 4Ω in stereo mode, and 500W RMS @ 8Ω in bridged mono mode.
• Parallel Power Transistor Architecture: Employs three pairs of precision-matched high-current transistors per channel to ensure uniform current distribution and high linearity.
• 800W Toroidal Linear Power Supply: Custom low-noise transformer supported by 24 audio-grade filter capacitors to handle dynamic peaks without voltage sag.
• Integrated AC DC Blocker Circuit: Suppresses DC offset present in mains AC power, preventing transformer core saturation, acoustic hum, and mechanical vibration.
