Marantz CINEMA 40 AV Receiver, 9.4 Channels, 125 W per Channel, 8K, Dolby Atmos, HEOS

Reference 9.4-channel receiver with 125 W per channel and seven 8K HDMI inputs for a high-end home cinema.

The Marantz CINEMA 40 is a reference AV receiver with 9.4 channels and 125 W per channel into 8 ohms, built for full Dolby Atmos, DTS:X and Auro 3D layouts. Processing extends to 11.4 channels, and pre-amp outputs for every channel leave room for external power stages later. Built-in HEOS ties the system into other rooms and the major streaming services.

Nine discrete Class A/B amplifier channels

Output is rated 125 W per channel into 8 ohms across 20 Hz – 20 kHz, with Marantz guaranteeing at least 70% of that figure with five channels driven. The design uses the brand's own HDAM modules and current feedback topology for its familiar warm, detailed character. Eleven speaker terminals allow bi-amp wiring of the front pair.

Seven 8K HDMI inputs and three outputs across two zones

Every input accepts 8K/60Hz and 4K/120Hz with HDCP 2.3, while the three outputs serve the main room and a second zone. Gaming is covered by ALLM and VRR, with Dolby Vision, HDR10+, HLG and Dynamic HDR support plus upscaling of 1080p and 4K sources to 8K.

HEOS multiroom with three zones and streaming services

Audio can be distributed to three zones, with zones 2 and 3 fed either from speaker terminals or pre-outs. Network and Wi-Fi bring TIDAL, Spotify Connect, Amazon Music, Deezer, Qobuz and TuneIn internet radio, alongside AirPlay 2 and Roon. Control runs through the Marantz AVR and HEOS apps, or by voice via Alexa, Google, Siri and Josh.ai.
