Other features included with the MI347:

• Power Guard^® signal overload technology that prevents overdriving and damaging your speakers
• Sentry Monitor^™ short-circuit protection circuit that disengages the output stage should current ever approach unsafe operating levels and then resets automatically when operating conditions return to normal
• Power Control to automatically turn other connected McIntosh components on and off
• Eco-friendly on/off signal sensing that turns the unit off if no input signal has been detected for a set amount of time and – perhaps more conveniently – automatically turns the MI347 on when it senses a signal from your home theater pro
