{"product_id":"eversolo-amp-f8","title":"Eversolo AMP-F8 Class AB Stereo Power Amplifier","description":"\u003cp\u003eThe Eversolo AMP-F8 is a Class AB stereo power amplifier with Class A bias, built for high-end two-channel systems. It delivers 180 W per channel into 8 ohms and 280 W into 4 ohms, or 500 W into 8 ohms bridged, with total harmonic distortion held to 0.003% and a 115 dB signal-to-noise ratio. Twin analogue VU meters sit across the front panel. As Eversolo’s official U.S. distribution partner, Forté Distribution brings the AMP-F8 to North American systems with full manufacturer warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClass AB with Class A Bias\u003c\/strong\u003e\u003cbr\u003eAt low listening levels the AMP-F8 runs in Class A, where the output devices never stop conducting and crossover distortion does not arise. As dynamic demand climbs the amplifier transitions to Class AB, keeping thermal load and current draw in proportion to what the music actually asks for. This is a deliberate compromise in favour of the volumes at which most listening happens, and it avoids the standing heat penalty of running pure Class A across the full output range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLinear Power Supply\u003c\/strong\u003e\u003cbr\u003eA toroidal transformer sits at the centre of the linear power supply. Supply reserves matter less for sustained output than for transient headroom: the moment an orchestral crescendo demands current faster than the supply can deliver is the moment an amplifier audibly compresses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Stage and Channel Isolation\u003c\/strong\u003e\u003cbr\u003eThe output stage uses matched MOSFET devices. Left and right amplification stages are independent, holding crosstalk to 95 dB down, and a damping factor above 400 gives the amplifier firm control over woofer motion. Over-current, over-temperature and short-circuit protection run continuously, and an efficient heat-dissipation structure keeps the amplifier stable in long sessions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMetering, Gain and Standby\u003c\/strong\u003e\u003cbr\u003eTwo analogue VU meters sit on the front panel, with a rear switch to disable their backlight for darkened rooms. A dual-colour LED ring around the standby button reports state at a glance: white for active, orange for standby, alternating for protection. Each channel takes either balanced XLR or unbalanced RCA, chosen by its own rear input-mode selector, and a 23 dB \/ 29 dB gain switch matches the amplifier to speakers of differing sensitivity. Standby follows a 5 to 12 V trigger from a preamplifier or processor, or can be left in signal-sensing mode, where the amplifier stands down after twenty minutes without signal and wakes when music returns.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBridged Mono Operation\u003c\/strong\u003e\u003cbr\u003eA rear switch reconfigures the AMP-F8 for bridged mono, raising output to 500 W into 8 ohms for use as a monoblock pair. Bridged operation is rated for 8 ohm loads only; 4 ohm bridged is not supported. Power the amplifier down and disconnect the speakers before changing the mode switch, and confirm that speaker impedance and power handling suit the higher bridged output before use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVoltage Selection\u003c\/strong\u003e\u003cbr\u003eThe AMP-F8 ships with a 115 V \/ 230 V selector on the underside of the chassis. Confirm that it matches your local mains standard before connecting power for the first time.\u003c\/p\u003e","brand":"Eversolo","offers":[{"title":"Default Title","offer_id":42643702743086,"sku":"EVERSOLO-AMP-F8","price":1800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0035\/4058\/2446\/files\/A.jpg?v=1787237155","url":"https:\/\/audioartcable.com\/products\/eversolo-amp-f8","provider":"Audio Art Cable","version":"1.0","type":"link"}
