Solid State Power Amp Reviews

Description: Solid state class-AB mono power amplifier, direct-coupled with hand-calibrated, precision balanced input stage. Inputs: 1 balanced (XLR). Outputs: JMF Audio's proprietary gold-plated, 120A-rated, 6mm-diameter LSS terminals (female) and WBT modular gold-plated terminals (male) for spades, wire, and 4mm-diameter banana plugs. Rated output power: 300W into 8 ohms (24.8dBW), 500W into 4 ohms (24dBW), 850W into 2 ohms (23.3dBW). Maximum output current: 112A. Minimum load impedance: 1.5 ohms recommended, tested down to 1 ohm; intentionally limited for amplifier and loudspeaker protection. Input impedance: 20k ohms. Interference rejection: 100dB typical, based on psychoacoustic criteria. Monitoring: Input offset, overload, over temperature, level metering (–15dB–+3dB), deactivatable. Frequency response: 3Hz–20kHz for 250W into 4 ohms, ±0.1dB; –1dB at 100kHz for small signals. THD+N: <0.01% at 250W into 4 ohms, 1kHz; 0.001% typ. unloaded. S/N ratio: 110dB typ., unweighted, 20Hz–20kHz. Damping factor: >1200 wideband with an 8 ohm load.
