McIntosh MX170 Home Theatre A/V Processor


Experience movies in the comfort of your home theater with the brilliance of 4K Ultra HD, the vividness of High Dynamic Range (HDR), and the immersiveness of 3D surround sound like never before with the MX170 A/V Processor.

To produce this immersive home theater experience, the MX170 features balanced outputs for a 15.1 surround sound speaker configuration.
This allows you to have a multitude of speakers in your home theater to create an enveloping cinematic soundstage.
If you don’t have that many surround sound speakers, 4 of the outputs can be used to bi-amp some of your speakers or to drive additional subwoofers.

HDR formats HDR10, Dolby Vision™ and HLG are also fully supported by the MX170.
When watching a video mastered in one of these formats, you’ll see a dramatic improvement in color, contrast and brightness on your screen.
It also has 3D video pass-through, so you can be right in the middle of the action when watching your favorite 3D movies.
