Denon AVC-X2850H Hi-Fi AV Receiver

7.2-Channel AV Amplifier with Dolby Atmos, 8K Video, and HEOS Built-in

The Denon AVC-X2850H is the centrepiece of Denon's current X-Series AV amplifier lineup. Built around a discrete 7-channel Class A/B amplifier rated at 95 W per channel into 8 ohms, it drives everything from a compact 5.1 setup to a full 5.2.2 Dolby Atmos configuration. Support for 8K/60 Hz, 4K/120 Hz, HDR10+, and Dolby Vision keeps the picture side future-proof for years of display upgrades.

What Sets This Amplifier Apart

Two refinements carried over from higher-tier Denon models make this amplifier unusually capable at its tier. The HDMI Pure CTS generator cleans up clocking errors on the HDMI bus, which the brand credits with measurable gains in sound quality over the previous generation. A built-in Bluetooth transmitter with adjustable level routes TV audio to wireless headphones for late-night listening, with separate volume from the main speakers.

Amplification Performance — Discrete Class A/B Power

Power and control matter as much as feature lists, and this model delivers both through a discrete high-current Class A/B topology. The 95 W per channel figure is measured with all channels driven into 8 ohms across the full 20 Hz–20 kHz band at 0.08% THD.

• Channels: 7 powered (7.2 processing) — drives a full surround array or 5.2.2 Atmos layout
• Power Output: 95 W per channel (8 ohm, 20 Hz–20 kHz, 0.08% THD, 2 ch driven)
• Peak Power: 150 W per channel (6 ohm, 1 kHz, 1% THD, 1 ch driven) — headroom for dynamic peaks in movie soundtracks
• Frequency Response: 10 Hz – 100 kHz — extends well beyond the audible band for accurate Hi-Res playback
• Signal-to-Noise Ratio: 100 dB — quiet background that lets quiet film details breathe

Video & HDMI — 8K Ready with Full Gaming Support

HDMI is the busiest connector on any modern AV amp, and this model gives it serious bandwidth. Three of the six HDMI inputs handle 8K/60 Hz and 4K/120 Hz signals, with HDCP 2.3 on every socket.

• HDMI: 6 inputs (3 × 8K) / 2 outputs (1 × eARC) — connects a console, Blu-ray player, and TV at once
• HDR: HDR10, HDR10+, Dolby Vision, HLG, Dynamic HDR — every major HDR standard for streaming and disc playback
• Gaming: VRR, ALLM, QFT, 4K/120 Hz pass-through — eliminates screen tearing and input lag on PS5 and Xbox Series X

Connectivity & Streaming — HEOS, AirPlay 2, Roon, and Bluetooth

Beyond HDMI, this amplifier is built as a complete streaming hub. HEOS Built-in anchors a multi-room ecosystem that scales across the home, while AirPlay 2, Spotify Connect, Bluetooth, and Roon Ready cover every modern workflow. The included moving-magnet phono input lets a turntable plug straight in without an external stage.

• Network: Wi-Fi, Ethernet — wired or wireless connection to the home network
• Wireless Streaming: HEOS, AirPlay 2, Bluetooth (with transmitter), Spotify Connect, Roon Ready
• Hi-Res Audio: ALAC, FLAC, WAV up to 24-bit/192 kHz; DSD 2.8/5.6 MHz
• Analogue & Digital Inputs: 5 RCA + MM Phono, 2 × Optical — turntable-ready plus legacy TV and CD sources
• Subwoofer Outputs: 2 × RCA — run dual subs for smoother bass across the room
• Room Calibration: Audyssey MultEQ XT — measures and corrects the speaker response for the specific room

Who Should Choose This Amplifier

The AVC-X2850H is the right choice for home cinema buyers who want Dolby Atmos, 8K video, and serious amplification without stepping up to a nine-channel flagship. It suits a 5.2.2 Atmos layout with two ceiling or up-firing speakers for genuine overhead effects, or a 7.2 layout for traditional surround. Next-generation console gamers get the full HDMI 2.1 feature set for tear-free, low-latency gameplay. Vinyl listeners benefit from the built-in MM phono input, while multi-room households can group the amplifier with HEOS-compatible speakers and soundbars through a single app.
