Dynamic Power
Detailed Presentation
The AMP-F2, developed in collaboration between the Starke Sound team and the EverSolo team, is based on the innovatibe NS600 module created by the Starke Sound team. It boasts a high sampling rate of up to 600kHz. Simultaneously, it significantly reduces noise and enhances dynamic performance through the newly designed SAPS audio-specific switch power supply. It employs an efficient Class D amplification structure, coupled with optimized circuits to maximize audio quality. The AMP-F2 is bridgeable, allowing flexible configuration for 2-channel or mono-channel setups when needed
 
Vigorous Output
Bridged Support
The AMP-F2 is equipped with Starke Sound's NS600 amplifier module, each channel can output a constant 250W RMS (4Ω) @ 1% THD+N. When bridged, it can support up to 450W RMS (2Ω) with THD+N still below 1%. This ability to handle extremely low-impedance loads ensures ample energy even in large and challenging speakers setups, particularly during high-dynamic low-frequency outputs.
 
Accurate Sound
Perfect Experience
The NS600 module employs PurePath Ultra-HD technology and advanced integrated feedback design, featuring high-speed gate driver error correction functions. This technology achieves ultra-low distortion across the entire audio frequency range, delivering perfect high-end audio quality
 
Powerful Power Drive
Utilizing a 600W high-efficiency, low-ripple, low-EMI switch power supply, it delivers consistent and powerful output, extremely low noise, enhancing the overall dynamic performance of the system.
 
Plenty of power
Based on a Class D NS600 amplifier module from Starke Sound, the EverSolo AMP-F2 is capable of delivering significant power, up to 2x250W RMS at 4 Ohm (1% THD). When the amplifier is used bridged (BTL), i.e. in mono, its power rises to 450W RMS at 2 Ohm (1% THD). This ability to support very low load impedances ensures sufficient power even in configurations using particularly demanding loudspeakers.

Power supply
Using a 600W switching power supply with high efficiency, low ripple and EMI, the EverSolo AMP-F2 is capable of delivering a stable and powerful output, enhancing the overall dynamics of the system. 
 
Aluminum chassis and shielding
The EverSolo AMP-F2 amplifier features a modern, robust aluminum chassis. Aesthetically pleasing, it also acts as a shield, limiting the impact of interference on the AMP-F2’s circuits. 
 
Energy saver
AMP-F2 has an extremely low standby power (0.5W) and idle power consumption (14W), complying with the European Union ErP standards.
