Solid State Power Amp Reviews

Description: Solid-state stereo power amplifier. Rated power output: 125Wpc into 2 to 8 ohms (15–21dBW), 100Wpc into 1 and 16 ohms (11 & 23dBW), 250Wpc into 3 ohms (maximum) (19.7dBW), both channels driven. Maximum voltage swing: 45V peak, both channels driven. Maximum current swing: 30A peak, both channels driven. Transient Intermodulation Distortion (TID): less than 0.01% (–80dB) up to 25V output into 8 ohms. Total Harmonic Distortion (THD): less than 0.01% (–80dB) up to 25V output into 8 ohms. Frequency response: DC–100kHz, ±0.1dB; DC–400kHz, ±1dB; DC–800kHz, ±1dB (all up to rated power). Crosstalk: !w90dB, common ground. Input impedance: 50k ohms. Input sensitivity: 1.55V RMS for rated output. S/N ratio: better than 100dB, 20Hz–20kHz; better than 110dB, A-weighted. Risetime: less than 700ns. Slew rate: greater than 100V/µs. Damping factor/output impedance: not specified.
