Class AB stereo power amplifier with VU meters The Eversolo AMP-F10 is a Class AB stereo power amplifier delivering 200 W RMS per channel into 8 Ω, and up to 450 W into 2 Ω. Designed to follow a preamplifier or a network player such as the Eversolo DMP-A10, it provides the current reserve that difficult or low-sensitivity speakers require. Its analogue front-panel VU meters continuously display the power being delivered. Dual mono topology and linear power supply The AMP-F10 is built on a fully balanced dual mono architecture: each channel has its own linear power supply with toroidal transformer, which limits interaction between channels and preserves stereo separation at high power. The output stage uses five pairs of high-current power MOSFETs per channel. The result is total harmonic distortion plus noise of 0.008%, a signal-to-noise ratio above 113 dB A-weighted and a damping factor above 600 at 1 kHz into 8 Ω — a sign of firm control over bass drivers. Frequency response extends from 10 Hz to 30 kHz (±0.5 dB into 8 Ω). Bridged mode: two monoblocks from a single amplifier A switch shifts the unit from stereo operation to bridged mono. In this configuration the amplifier delivers 650 W into 8 Ω and 950 W into 4 Ω. Two bridged AMP-F10 units thus form a pair of monoblocks, each speaker getting its own amplifier — a possible upgrade path without changing equipment if the system grows or the speakers become more demanding. Gain settings, connectivity and VU meters The balanced XLR and unbalanced RCA inputs are switchable, with an input impedance of 10 kΩ, allowing connection to most preamplifiers and sources with variable output. Gain can be set to 23 dB or 29 dB to match the amplifier's sensitivity to the source's output level and to the usable range of the volume control. A 12 V trigger in and out allows automatic power-up and shutdown with the rest of the chain. On the front panel, the two analogue VU meters display power in watts and in dB. With a 430 × 310 × 147 mm chassis weighing 18 kg, the AMP-F10 fits into a standard hi-fi rack, provided there is adequate ventilation above the unit.
