The McIntosh MI347 7-Channel Digital Amplifier is a high-performance, Class D power amplifier specifically designed for immersive home theater. It delivers robust power of 250 Watts per channel into 8 Ohms and 300 Watts per channel into 4 Ohms, with all seven channels driven simultaneously, ensuring dynamic and impactful surround sound.

Utilizing highly efficient Class D amplification, the MI347 runs cool, enabling flexible installation. It features 7 balanced XLR and 7 unbalanced RCA inputs for seamless integration with any A/V processor. McIntosh’s patented Power Guard® and Sentry Monitorâ„¢ technologies provide comprehensive speaker and amplifier protection. Housed in a classic McIntosh black glass front panel with an illuminated logo and polished stainless steel chassis, the MI347 combines powerful performance, legendary reliability, and iconic aesthetics for an unparalleled cinematic audio experience.

- 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 processor
