McIntosh MX100 Home Theatre A/V Control Processor


The MX100 A/V Processor is designed for today’s home theaters that only need digital inputs and don’t require any legacy analog inputs that were used in past years, decades, and centuries.
It offers unparalleled McIntosh home theater performance in a streamlined design that gives you exactly what you need to enjoy all your favorite HD and 4K programming, Blu-ray and 4K Ultra HD discs, and DVDs.

The MX100 is compatible with leading home theater surround sound and object-based 3D audio formats Dolby® Atmos and DTS:X™.
It’s also fully compatible with 4K Ultra HD video sources for the best possible picture quality.
To further help deliver the clearest and most earth-shattering sound possible, the MX100 can be fine-tuned to your home theater’s unique acoustical properties via the built-in Audyssey MultEQ® XT32 calibration software that has more than ten thousand individual control points allowing finer details of the room’s problems to be captured and corrected.

It’s well suited to be installed in a hidden or out-of-the-way A/V equipment rack.
It has rack-friendly 2U physical dimensions and rack mounting brackets to facilitate installation (the mounting brackets are removable for non-rack installations).
Not limited to just rack installation, it also looks and works well when placed out in the open for all to see and enjoy.

The MX100 can be used with any combination of McIntosh home theater amplifiers, such as the MI347 7-Channel Amplifier – which is rack mountable just like the MX100, the MC255 5-Channel Amplifier, or the MC257 7-Channel Amplifier among others.
If you’re using additional surround sound or ceiling speakers, add the MI254 4-Channel Amplifier or MI128 8-Channel Amplifier (both also rack mountable) to completely power your home theater with McIntosh power.
