Eversolo - AMP-F2 - Class D Stereo Power Amplifier

Eversolo - AMP-F2 - Class D Stereo Power Amplifier
The Eversolo AMP-F2 is a compact Class D stereo power amplifier developed in collaboration with Starke Sound. Designed to complement Eversolo’s network music players and DAC-preamplifiers, it provides substantial output power without requiring the cabinet space of a conventional full-size amplifier. Its understated aluminum enclosure, fanless operation and matching proportions make it especially well suited to streamlined two-channel audio systems.
A Starke Sound NS600 amplifier module and newly designed 600W SAPS audio-specific switch-mode power supply form the foundation of the AMP-F2. The amplifier delivers 145W per channel into 8 Ohms and 250W per channel into 4 Ohms, with a maximum current capability of 16.5A per channel. Fully balanced circuitry, a signal-to-noise ratio greater than 110dB and distortion rated at 0.003% at 10W help provide a quiet background, precise detail and controlled dynamic reproduction.
Balanced XLR and unbalanced RCA inputs allow the AMP-F2 to connect with a wide selection of preamplifiers, DACs and network streamers. It can operate as a conventional 2-channel stereo amplifier or be switched into bridged mono mode when greater single-channel power is required. Custom beryllium-copper speaker terminals provide secure connections, while 12V trigger input and output connections allow synchronized power control with compatible source components and additional amplifiers.
