Description
The MI347 7-Channel Power Amplifier is purpose-built for high-performance home theater systems, delivering the power, clarity, and reliability that McIntosh is known for. As a digital amplifier, it provides exceptional efficiency and dynamic output, with its 3 front channels delivering 250 watts into 8 ohms or 300 watts into 4 ohms, ensuring powerful, detailed sound for the most critical front-stage speakers. The 4 surround channels supply 125 watts into 8 ohms or 200 watts into 4 ohms, offering ample energy to drive immersive surround effects with precision and consistency.
Engineered with McIntosh’s advanced protection technologies, the MI347 includes Power Guard® to prevent distortion and speaker damage from overdrive, along with Sentry Monitor™ to safeguard the amplifier from short-circuit conditions. Its on/off signal sensing feature provides smart, energy-efficient operation by automatically powering the unit up or down based on audio signal presence. Designed for custom installations, the amplifier is 3U rack mountable, allowing seamless integration into modern equipment racks while maintaining optimal airflow and a professional layout. Delivering robust multi-channel output, advanced safety features, and installation flexibility, the MI347 stands as a reliable, high-performance solution for today’s immersive home theater environments.
Edge-Of-Your-Seat Audio Experience
The MI347 7-Channel Digital Amplifier is a dedicated home theater amplifier that delivers an immersive sonic experience that provides a heart-stopping, edge-of-your-seat audio experience in the comfort of your home theater. It uses highly sophisticated closed loop digital switching amplifiers that are paired with extremely robust power supplies that produce audio performance levels rarely heard in home theaters.
Meant to be heard more than seen
such as being installed in an out-of-sight A/V equipment rack, the MI347 has a simplified and understated exterior. But rest assured that the internal circuitry and components have received the full attention of the McIntosh engineers to make you feel like you are part of your favorite movies. With its rack-friendly 3U height, it can easily be installed in your A/V rack via the included rack mounting brackets (the mounting brackets are removable for non-rack installations). But the MI347 is not limited to just rack installations, as it can also be placed out in the open for all to see and enjoy.
MI347 Rack Mounting Bracket Front and Back Overview
The front of the MI347 rack mounting bracket showcases McIntosh’s signature aesthetic, featuring a beautifully crafted black glass panel complemented by silver trim. This refined design integrates multi-color LED indicators that clearly display the status of each channel, making it easy for users to monitor performance at a glance. The front is engineered to blend seamlessly into any professional rack setup or high-end home theater system while maintaining the iconic McIntosh identity with its softly illuminated McIntosh logo.
The back of the rack mounting bracket reveals a thoughtfully organized layout built for maximum connectivity and installation convenience. Every channel includes both balanced and unbalanced inputs, allowing flexible integration with a variety of processors and audio systems. High-quality 5-way speaker binding posts ensure secure, reliable speaker connections. The rear panel also incorporates numerous ventilation points designed to keep the powerful Class D amplifier cool without the need for noisy cooling fans, delivering silent and efficient thermal performance.
Power Distribution for Home Theater Performance
The MI347 is engineered to deliver powerful, precise audio performance in a modern home theater environment. The front left, front right, and center channels responsible for dialogue clarity and the most impactful cinematic effects each receive 250 Watts at 8 Ohms or 300 Watts at 4 Ohms, ensuring uncompromised sound reproduction. The remaining four channels are optimized for surround and ceiling speakers, delivering 125 Watts at 8 Ohms or 200 Watts at 4 Ohms, offering clean, immersive sound throughout the entire room. This thoughtful power distribution ensures that all critical speaker channels perform at their peak.
Silent, Efficient Thermal Design
Built with a highly efficient Class D amplifier topology, the MI347 operates with exceptional energy efficiency. Thanks to its advanced thermal management design, it does not require internal cooling fans, eliminating unwanted noise during playback. Instead, the amplifier uses expansive ventilation openings across the top and sides to naturally dissipate heat. This allows the unit to run cool and quiet, even under demanding operation, making it an ideal choice for dedicated home theaters and rack-mounted systems.
Comprehensive Connectivity & Control
The MI347 offers extensive connectivity to support a wide range of home theater setups. The rear panel includes both balanced (XLR) and unbalanced (RCA) input options for every channel, providing the flexibility needed for professional-grade installations. The amplifier integrates seamlessly with McIntosh home theater processors such as the MX123, MX180, and rack-mountable MX200. For setups requiring more than seven audio channels such as Dolby Atmos or DTS:X configurations the MI347 pairs effortlessly with additional McIntosh amplifiers like the MI254 or MI128, ensuring full coverage for expansive multi-channel environments.
Advanced Protection & Smart Features
To protect connected speakers and maintain long-term reliability, the MI347 includes McIntosh’s signature technologies. Power Guard® prevents signal clipping and potential speaker damage, while Sentry Monitor™ continuously checks for short-circuit conditions, automatically resetting once normal operation is restored. The amplifier also features Power Control, allowing synchronized on/off operation with other McIntosh components. Additionally, signal sensing technology ensures energy efficiency by automatically powering down when no audio signal is detected and turning on instantly when input is restored.
Iconic McIntosh Design Elements
Beyond performance, the MI347 reflects the timeless McIntosh design philosophy. Its signature black glass front panel, illuminated logo, handcrafted metalwork, and classic form factor bring unmatched visual elegance to any rack or theater room. Designed for both durability and beauty, the MI347 stands as a premium centerpiece in professional home cinema installations.
