McIntosh’s New Home Theater Offerings Provide Compact Versatility

McIntosh’s new home theater offerings are designed to be heard, and not seen, if you prefer. The 2U MX100 A / V Processor has four HDMI inputs and one HDMI output, all of which are HDCP 2.2 compliant and support Dolby Vision, HDR10 and HLG. In addition, the HDMI output offers eARC functionality. With 11.2 audio channels and 13 balanced connections, the MX100 offers excellent audio reproduction and is compatible with both Dolby Atmos and DTS: X.

The 7-channel digital amplifier 3U MI347 was developed for coupling with the MX100 and delivers 250 watts into 8 ohms or 300 watts into 4 ohms to the front left, front right and center channel speakers in a home theater setup. The amplifier delivers 125 watts at 8 ohms or 200 watts at 4 ohms to the four remaining channels. The MI347 class D can be combined with the 4-channel digital amplifier MI254 or the 8-channel digital amplifier MI128 for home theaters with more than seven audio channels. In addition, the new amplifier is equipped with Power Guard to prevent signal overload and a short-circuit protection circuit from Sentry Monitor.

Both the A / V processor MX100 and the 7-channel digital amplifier MI347 are equipped with the McIntosh logo and the black glass front. Available now from November. Both the MX100 and MI347 retail for $ 5,000.

Here is more information from McIntosh on the new releases:

McIntosh, the global leader in prestigious home entertainment and high quality audio for over 70 years, is proud to introduce two more exciting products: the MX100 A / V Processor and the MI347 7 Channel Amplifier.

The MX100 and MI347 represent a streamlined approach to the McIntosh Home Theater product offering. Both are designed to be heard more than seen. They can be easily mounted in a hidden or remote A / V equipment rack. Accordingly, the MX100 has a height of 2 U and the MI347 a height of 3 U. Or if desired, they can be left open for all to see and enjoy. The combination of the MX100 and MI347 gives you a premium home theater experience.

MX100 A / V Processor (2U rack mounting height)

The MX100 A / V Processor is designed for today’s home theaters that only need digital inputs and do not require the older analog inputs that have been used in years past, decades and centuries. It offers unprecedented McIntosh home theater performance in a streamlined design that gives viewers exactly what they need to enjoy all of their favorite HD and 4K programming.

It has 4 HDMI inputs and 1 HDMI output, all of which are HDCP 2.2 compliant. Each HDMI port also has a bandwidth of 18 Gbps to support the HDR (High Dynamic Range) formats Dolby Vision, HDR10 and HLG. 4K Ultra HD at 50/60 Hz; 4: 4: 4 color distance; Rec. 2020; and 3D video pass-through. The HDMI output has an extended eARC functionality (Audio Return Channel). eARC provides improved bandwidth so the MX100 can receive higher resolution audio from a television for the best possible sound quality. Two coax and two optical digital audio inputs are also included.

For audio output, the MX100 has 11.2 (or 7.2.4) discrete audio channels and 13 balanced (XLR) connections. Seven world-class 32-bit digital-to-analog converters (DACs) provide audiophile processing for the best audio reproduction. Using only balanced outputs ensures that the cleanest sound is sent through the audio cables to the amplifiers and ultimately to the speakers and subwoofers.

The MX100 is compatible with leading home theater surround sound and object-based 3D audio formats Dolby Atmos and DTS: X. It is also fully compatible with 4K Ultra HD video sources for the best possible picture quality. For the clearest, most earth-shaking sound, the MX100 can be detected and corrected through the built-in Audyssey MultEQ XT32 calibration software with more than ten thousand individual control points that allow finer details to be fine-tuned to the unique acoustic properties of each home theater and problems in the room.

Setup can easily be performed via the computer interface and can even be preconfigured by the installation program to save on-site installation time. The configuration file can be saved on a computer or USB stick for safe storage. The MX100 can be operated entirely via the remote control or simply integrated into a home automation system via the RS232 control protocol.

7-channel amplifier MI347 (3U rack mounting height)

The 7-channel digital amplifier MI347 is a dedicated home theater amplifier that offers an immersive sound experience that provides a breathtaking audio experience. It uses sophisticated digital closed-loop switching amplifiers that are combined with extremely rugged power supplies that produce audio power levels rarely heard in home theaters. While the MI347 has a simplified and understated exterior, the internal circuitry and components have received the full attention of McIntosh engineers to make the viewer feel part of the film.

In a home theater, the most important audio channels or speakers are the front left, front right, and center speakers. Much of the dialogue and the loudest and most famous special effects resonate here. Therefore, the MI347 delivers 250 watts at 8 ohms or 300 watts at 4 ohms to each of these three speakers. The other four channels of the MI347 are supposed to control the still important, but less power-hungry surround sound speakers. For each of these four channels, the MI347 delivers a healthy 125 watts at 8 ohms or 200 watts at 4 ohms.

The MI347 is a highly efficient Class D amplifier and does not require loud fans to maintain the rated operating temperature. It also features an abundance of cooling slots on the top and sides to further aid in heat dissipation. On the front, multi-colored LED indicators show the status of each channel. The rear panel has both a balanced and an unbalanced input for each channel.

The MI347 is ideal for interfacing with the McIntosh MX100 A / V Processor, but can also be used with the McIntosh MX123 and MX170 processors or with virtually any home theater processor. If there are more than 7 audio channels in the home theater, e.g. With Dolby Atmos or DTS: X, the McIntosh 4-channel MI254 digital amplifier or the MI128 8-channel digital amplifier (both rack mountable) can be added to provide all McIntosh power to the speakers.

Other MI347 features include: Power Guard signal overload technology that prevents overdriving and damaging the speakers; Sentry Monitor short circuit protection circuit that shuts down the output stage if the current ever approaches unsafe operating levels; Power Control to automatically turn other connected McIntosh components on and off; and eco-friendly on / off signal capture, which turns the unit off when no input signal is detected for a set period of time and, perhaps more conveniently, automatically turns on the MI347 when it detects a signal from the home theater processor.


Both the MX100 and MI347 have streamlined designs while still incorporating many McIntosh design elements including a black glass front, an illuminated McIntosh logo, rotary knobs (MX100 only), and a familiar form factor highlighted by silver trim. Their timeless appearance makes them look like at home, with other McIntosh products, or with other home theater devices.
