Marantz Cinema 70s Slimline 7.2ch AV Receiver

Full Home Theatre Sound in Half the Height

The Marantz Cinema 70s Slimline 7.2ch AV Receiver packs seven channels of discrete amplification, Dolby Atmos and DTS:X decoding, and 8K video into a chassis just 109mm tall. It is built for racks and living rooms where a full-height receiver will not fit, without giving up the Marantz sound signature. HEOS streaming and AirPlay 2 are built in, so it slots into a multi-room system straight out of the box.

Why You'll Love It

• Slimline by design. At 109mm tall and 8.7kg, the Cinema 70s fits shelves and cabinets a standard receiver cannot, with the iconic Marantz porthole OLED display carrying the family look.
• Every major immersive format. Dolby Atmos, Dolby TrueHD, DTS:X and DTS Neural:X are decoded on board, with height virtualisation for rooms without overhead speakers.
• Streaming and multi-room built in. HEOS, AirPlay 2, Spotify Connect and TuneIn are ready to go, and the receiver runs two independent zones for sound in another room.

Under the Hood

• Discrete 7-channel amplification. Seven channels of discrete Class A/B power deliver 50W each into 8 ohms (20Hz to 20kHz, 0.08% THD, two channels driven), with assignable bi-amp and speaker terminals.
• 8K-ready HDMI with gaming support. Six HDMI inputs (three rated for 8K) and one eARC output pass HDR10+, Dolby Vision and HLG, plus ALLM and VRR for console gaming.
• Room correction and dual subwoofers. Audyssey MultEQ with Dynamic EQ and Dynamic Volume tunes the system to your room, and twin subwoofer outputs let you run two subs for even bass.

CHT Insider Verdict

The Cinema 70s is where a lot of space-conscious Atmos builds land. You get genuine Marantz amplification and the full immersive format list in a box that hides on a shelf, which is exactly what most 5.1.2 and 7.2 living-room systems need. It is not built to drive large floorstanders in a big room, but for its size and target, little else matches the sound quality.

Pro Tip: Run it as a 5.1.2 system by assigning the two surround-back amp channels to your Atmos height speakers in the setup menu, then run the Audyssey calibration with the supplied microphone at seated ear height for the cleanest overhead effect.
