When it comes to the video requirements of a modern home theatre, the MX170 home theatre processor has everything you need. It has 8 HDMI inputs and 4 HDMI outputs that are powered by the newest and most powerful HDMI processors available. Each HDMI port is HDCP 2.2/2.3 and has 18Gbps of bandwidth to fully support 4K Ultra HD picture quality and full 4:4:4 color spacing. Audio Return Channel (ARC) capabilities are featured on 3 of the outputs, while the 4th features Enhanced Audio Return Channel (eARC) functionality. eARC offers improved bandwidth so higher resolution audio can be sent from your TV to the MX170 to deliver the best sound quality possible.

The combo of the McIntosh MX170 A/V Processor and MC257 7-Channel Amplifier “checked all the performance-related boxes when it came to signal integrity and immersion. Also, clarity and dynamics were off the charts… It had an amazing surround bubble that put me in the centre of the action. This soundscape featured pinpoint imaging of all the discrete effects. The overall clarity, dynamic punch, and low distortion of the sound were above reproach.” – SECRETS of Home Theatre and High Fidelity

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 colour, contrast and brightness on your screen. A special HDBaseT output is included to prevent signal loss or degradation when there is a long distance between your MX170 and the screen. It also has 3D video pass-through, so you can be right in the middle of the action when watching your favourite 3D movies.

On the audio side, the MX170 is compatible with all the leading object-based, 3D surround sound formats including Dolby® Atmos, DTS:X™ and Auro-3D® to give you a truly immersive theatre experience. It includes sophisticated RoomPerfect™ room correction technology that will measure and adjust the audio output to compensate for the specific acoustic properties of your room and make every seat in the house the best seat in the house. The MX170 combined with RoomPerfect will give you a home theatre surround sound system with optimized frequency response, calibrated speaker volumes, and bass control that perfectly combines your speakers with your subwoofer(s). You’ll also gain added flexibility in speaker selection and placement.

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 theatre 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.

The MX170 comes with a full suite of digital inputs including 4 optical, 3 coaxial and 1 USB that each accept up to 24-bit/192kHz signals, plus 1 digital balanced input. There’s also a complete complement of analog audio inputs comprised of 2 balanced and 4 unbalanced inputs, a phono input and a 7.1 multichannel unbalanced input. It features some of the latest analogue to digital convertor technology to maximize the audio quality of your analogue sources. All analogue and digital devices can be custom named to simplify system operation; their volume levels can be matched to eliminate jarring changes in volume when transitioning between sources. Bass and treble controls offer further audio fine-tuning.
