A-45A-45 Backview

Pure Class A power amplifier uses power MOS-FET devices to deliver 45 watts per channel (8 ohms). Fully balanced signal paths as found in high-quality instrumentation amplifiers. Further refined MCS+ topology and current feedback result in superb sound quality and excellent ratings for S/N ratio, THD, and other parameters. Strong power supply and power MOS-FET devices in six-parallel push-pull configuration sustain an amazing 360 watts per channel into ultra-low impedance 1-ohm loads (with music signals).
