  • Power Guard - McIntosh designed and patented circuit that prevents speaker clipping. Photo-optics react in 1/1000th of a second to regulate power levels to speaker, protecting the speakers and the amplifier. A waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion.
  • Sentry Monitor - McIntosh designed and patented circuit that activates in case of accidental “shorts" in speaker wires. Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level-resets automatically.
