Parasound NewClassic Series 2250 V2 Power Amplifier | 400W x 2 Channels

The Parasound NewClassic 2250 V2 is a two-channel power amplifier designed for high-current stereo and custom installation use. Housed in a 3U rack chassis, it produces 275 watts per channel into 8 ohms and 400 watts per channel into 4 ohms, with a load switch that allows operation at 2-ohm loads for compatibility with difficult speaker systems. It weighs 43 lbs net and measures 17.25 by 5.25 by 18.5 inches.

The amplifier delivers 45 amps peak current per channel and holds total harmonic distortion to 0.20 percent at full rated output, improving to 0.015 percent at typical listening levels. Signal-to-noise ratio reaches 114 dB IHF A-weighted at rated output. Channel crosstalk is 85 dB at 1 kHz, input impedance is 33 kilohms, and gain is fixed at 29 dB. Bridged mono operation yields 750 watts into 8 ohms, and the unit accepts a DC 9-12V external trigger.
