A bank of 24 custom audio-grade filter capacitors stores energy for sudden peaks, and a DC blocking circuit keeps DC offset on the AC line away from the transformer, which cuts down on mechanical hum and noise. The input stage is a dual differential design with symmetrical circuitry and precision negative feedback that rejects common-mode noise. The output stage runs three matched BJT pairs per channel in parallel, sharing current evenly so that distortion stays low across different speaker loads.\u003c\/p\u003e\n\n\u003ch3\u003eRear Panel and Setup\u003c\/h3\u003e\n\u003cp\u003eEversolo's rear-panel photography shows these connections and switches:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBalanced (XLR) and unbalanced (RCA) inputs for each channel, with a selector switch for each\u003c\/li\u003e\n  \u003cli\u003eA sensitivity switch for 23dB or 29dB of gain\u003c\/li\u003e\n  \u003cli\u003eA Stereo\/Bridge mode switch (the left inputs serve as the bridge inputs)\u003c\/li\u003e\n  \u003cli\u003eTrigger in and trigger out jacks, plus a standby switch for Trigger or Signal mode\u003c\/li\u003e\n  \u003cli\u003eAn LED on\/off switch\u003c\/li\u003e\n  \u003cli\u003eSpeaker binding posts for each channel, a master power switch, and an IEC power inlet\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For and System Pairing\u003c\/h2\u003e\n\u003cp\u003eThe AMP-F8 is a two-channel power amplifier.

In bridged mono mode it delivers 500W RMS into 8 ohms.\u003c\/p\u003e\n\n\u003ch3\u003eIs the AMP-F8 Class AB or Class D?\u003c\/h3\u003e\n\u003cp\u003eIt is Class AB. Each channel uses three pairs of precision-matched, high-current BJT power transistors running from an 800W toroidal linear power supply, not a switching amplifier or a switching power supply.\u003c\/p\u003e\n\n\u003ch3\u003eCan the AMP-F8 be bridged to mono?\u003c\/h3\u003e\n\u003cp\u003eYes. A rear-panel Stereo\/Bridge switch turns it into a mono amplifier rated at 500W RMS into 8 ohms, so two units make a pair of monoblocks. Eversolo publishes a bridged rating for 8-ohm loads only, so check your speakers' impedance before planning a bridged pair.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the AMP-F8 have balanced inputs?\u003c\/h3\u003e\n\u003cp\u003eYes. Each channel has one XLR balanced input and one RCA unbalanced input, both 10kΩ, with a switch to choose between them.\u003c\/p\u003e\n\n\u003ch3\u003eWhat gain settings does the AMP-F8 have?\u003c\/h3\u003e\n\u003cp\u003eIt has two gain settings, 23dB and 29dB, set by a switch on the rear panel. For full 180W output into 8 ohms, the XLR input needs 5.2V at 23dB or 2.6V at 29dB, and the RCA input needs 2.65V at 23dB or 1.3V at 29dB.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the AMP-F8 have a volume control?\u003c\/h3\u003e\n\u003cp\u003eNo. It is a power amplifier, so connect it to a preamplifier or to a DAC or streamer with a variable, volume-controlled output, such as the Eversolo DMP-A8 Gen 2.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Eversolo components pair with the AMP-F8?\u003c\/h3\u003e\n\u003cp\u003eEversolo presents the AMP-F8 alongside the DMP-A8 Gen 2 streamer for a compact two-box system, and with the DMP-A8 Master Gen 2 and the C10 Master Clock for a more complete high-end setup.\u003c\/p\u003e\n\n\u003ch3\u003eCan the AMP-F8 turn on automatically with my source?\u003c\/h3\u003e\n\u003cp\u003eYes. It has trigger in and out jacks and comes with a trigger cable. A rear standby switch chooses between trigger mode and signal mode, so it can wake from a trigger signal or when it detects an incoming audio signal.\u003c\/p\u003e\n\n\u003ch3\u003eHow big and heavy is the AMP-F8?\u003c\/h3\u003e\n\u003cp\u003eIt measures 265 mm wide, 388 mm deep and 119 mm high (about 10.4 × 15.3 × 4.7 inches) and weighs 15.9 kg (about 35 lb), or 18.6 kg (about 41 lb) boxed.
