The McIntosh MI347 is a seven-channel Class D amplifier with different power capacities for the front and surround speakers. Its three front channels provide 250 watts into 8 ohms or 300 watts into 4 ohms; four surround channels provide 125 or 200 watts respectively.
Why This Model Matters
That division reflects a practical theater arrangement: reserve higher output for the front stage while supplying the remaining channels from the same chassis. The MI347 fits a 3U rack space and uses fanless cooling. It works behind an A/V processor, which handles formats, speaker setup, and volume. For an immersive system, additional amplification can serve height speakers while the MI347 powers the chosen bed-layer channels.
