Pros & Cons
👍 Pros
- Nine amplified channels at 125W each means no compromises when running a full surround layout — every speaker gets proper, clean power.
- Four subwoofer outputs let you run multiple subs in a large room or configure a dual-sub setup for more even bass distribution.
- Dolby Atmos, DTS:X Pro, IMAX Enhanced, and Auro 3D support covers every major immersive audio format — future-proof for the current content landscape.
- 8K/60Hz and 4K/120Hz HDMI pass-through with VRR and ALLM makes it a genuinely capable gaming hub for current-gen consoles.
- Audyssey MultEQ XT32 room correction takes the guesswork out of speaker setup and delivers optimized sound even in acoustically challenging rooms.
👎 Cons
- At this channel count and feature density, the physical unit is large and heavy — it needs substantial rack or cabinet space with adequate ventilation.
- The HEOS streaming app experience is functional but not as polished or responsive as native apps on a smart TV or dedicated streamer.
- 8K source content remains extremely limited, meaning the 8K pass-through capability is largely future-proofing rather than an immediately usable feature.
- The depth of the menu system and the number of configuration options can overwhelm users upgrading from a simpler soundbar or entry-level receiver.
Frequently Asked Questions
Does the Cinema 40 actually power all 9 channels simultaneously?
Yes — the Cinema 40 delivers 125W to each of its 9 amplified channels simultaneously, so a full 9.4 speaker layout runs without compromise. The ".4" refers to four subwoofer pre-out connections, which are line-level outputs, not amplified channels.
Do I need height speakers to get Dolby Atmos?
No. The Cinema 40 includes Dolby Height Virtualization and DTS Virtual:X, which simulate overhead sound from a standard 7.1, 5.1, or even 2.1 speaker arrangement. That said, adding physical height speakers will produce a noticeably more convincing 3D soundstage if your room allows for it.
How does the Audyssey MultEQ XT32 room correction work?
Audyssey MultEQ XT32 is an automated acoustic measurement system — you place a microphone (included) at multiple listening positions in your room, run a calibration sequence, and the receiver adjusts EQ, levels, and delay timing for each speaker to compensate for your room's acoustic properties. It takes about 15–20 minutes and significantly improves the out-of-box listening experience.
Is the Cinema 40 suitable for gaming, and does it support VRR?
Yes — it's a strong gaming receiver. It supports Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Quick Frame Transport (QFT), which together minimize input lag and screen tearing when connected to an Xbox Series X or PS5. The 4K/120Hz pass-through is the key spec for current-gen console gaming.
Can I stream music to it without turning on my TV?
Yes. The built-in HEOS platform, Wi-Fi, Bluetooth, and AirPlay 2 all operate independently of any HDMI source. You can stream Spotify, Pandora, or other HEOS-compatible services directly to the receiver — no TV required.
