Overview
Driving a large Atmos speaker layout with nine amplified channels, this Marantz receiver adds pre-amp outputs and four independent subwoofer channels for expansion. HEOS multi-room streaming, Wi-Fi and Bluetooth bring music services in alongside HDMI sources.
Wide format support and many HDMI connections make it a hub for a large system. Pre-amp mode on each channel lets power amplifiers take over later. Speakers, a remote and cables are not part of the listed contents, so budget for the rest of the system.
Who it's for
Home theater enthusiasts building an Atmos or Auro system around many sources and a long-term upgrade path. Casual users with a soundbar or a small room would not use the channel count.
Pros and cons
- Nine amplified channels
- Pre-amp mode on every channel
- Ten HDMI ports for many sources
- Support for four immersive formats
- Speakers not included
- Remote not named in the contents
- Heavy and deep chassis
- Software update support not stated
Performance notes
Nine amplifier channels drive the layout directly, and the pre-amp outputs let outboard amplifiers share the load for demanding speakers. Immersive formats place sound overhead when height speakers are fitted. The supplied Audyssey microphone helps calibrate the room, and the HDMI board passes high frame rate video.
