The Outlaw Audio 7900 is the flagship seven-channel power amplifier from Outlaw Audio, designed for high-end home theater and audiophile applications. It features a fully balanced design with 24 output transistors per channel, delivering 300 watts RMS per channel into 8 ohms across the full audio bandwidth (20 Hz to 20 kHz) with less than 0.05% total harmonic distortion. The amplifier supports a power bandwidth from 5 Hz to over 100 kHz and has a damping factor of 400, ensuring tight control over speakers. It includes automatic input selection between balanced XLR and semi-balanced RCA inputs, a high slew rate of 50 volts per microsecond for excellent transient response, and a remote trigger input compatible with 3-24 VDC signals. The 7900 requires dual 115 V power cords and dedicated 15-amp circuits due to its high power consumption (up to 2x 1440 watts). It weighs 145 pounds and measures 17.2 x 9.5 x 19.5 inches. The amplifier is discontinued but remains highly regarded for its robust power delivery and sonic performance, capable of driving demanding speakers with ease.
