Description: Solid-state, class-D, monoblock power amplifier. Inputs: 1 pair balanced (XLR), 1 pair single-ended (RCA), DC trigger. Outputs: 2 pairs five-way binding posts. Output power (120VAC mains, 1kHz, 1% THD): 350W minimum into 8 ohms (25.4dBW), 700W minimum into 4 ohms (25.4dBW), stable for musical transients into 2 ohms. Frequency response (2V RMS into 4 ohms): 10Hz–20kHz, ±0.5dB; 10Hz–50kHz, ±3.0dB. Voltage gain: 30.5dB, ±0.5dB. Sensitivity: 1.6V. Input impedance: single-ended, 50k ohms; balanced, 100k ohms. Output impedance: 0.007 ohm, 50Hz, 2.8V RMS. Damping factor (50Hz, 2.8V RMS): 8 ohms, >1100; 4 ohms, >550. THD+IM: 0.02% (1kHz, 1W/4 ohms); 0.02% (10Hz –20kHz, 1W/4 ohms); 0.05% (90kHz BW, 10Hz–50kHz, 1W/4 ohms); 0.01% (1kHz, 37.5W/4 ohms). Signal/noise: 105dB ref 1kHz at 700W. Power consumption: 23W (idle), 125W (1/8 power into 4 ohms); 895W (into 4 ohms at rated power output). Voltage options: Japan/US, 120V; Europe/Asia, 230V.
