High-end US audio outfit McIntosh has turned its attention to home theatre, with the launch of the MX100 AV processor and MI347 seven-channel amplifier.

The MX100 and MI347 are designed for AV equipment racking, with the MX100 just 2U tall and the MI347 3U. While slim, the MX100 and MI347 still include many McIntosh design cues, including a black glass front panel, an illuminated McIntosh logo.

The MX100 AV processor shuns analogue, and only offers digital inputs. It has four HDMI inputs and one HDMI output with eARC, with each HDMI port promising to support High Dynamic Range (HDR) formats Dolby Vision, HDR10 and HLG; 4K at 50/60Hz; 4:4:4 color spacing; Rec. 2020; and 3D video pass-through.

There’s also for digital audio inputs (split between coaxial and optical). Codec support covers Dolby Atmos and DTS:X. The MX100 is a 7.2.4 / 11.2 design and offers 13 balanced (XLR) connectors. There are seven premium 32-bit Digital-to-Analog Converters (DACs) onboard.

Setup, using MultEQ XT32 calibration software, is performed via computer interface, and it can be pre-configured by the installer to save on-site installation time. The configuration file can be backed up onto a computer or USB stick for safe keeping. The MX100 can be incorporated it into a home automation system using RS232.

The partnering MI347 7-channel amplifier can deliver 250 Watts at 8 Ohms or 300 Watts at 4 Ohms to the front soundstage. The MI347's other four channels deliver 125 Watts at 8 Ohms or 200 Watts at 4 Ohms.

Using efficient Class D amplification, the MI347 does not require noisy cooling fans to maintain nominal operating temperature; it also features cooling vents on the top and sides to further assist with heat dissipation.

If required, McIntosh MI254 four channel or MI128 eight channel amps (also rack mountable) can be added to deliver McIntosh power to all the speakers.

Shipping in the US from November, MX100 and MI347 are priced at $5000 a piece.
