Denon AVR-X3900H 8K 9.4 Channel AV Receiver

A Serious Home Theater Today, With Room to Grow Tomorrow

Most home theaters start with five speakers and a subwoofer. Then come height speakers for Dolby Atmos, a second subwoofer, maybe a bigger screen. The receiver at the center decides how far you can go without starting over.

The Denon AVR-X3900H is a 9.4-channel receiver with 105 watts per channel and 11.4-channel processing. It plays Dolby Atmos, DTS:X, Auro-3D, IMAX Enhanced and 360 Reality Audio, and drives up to four subwoofers. Denon says each product is hand-tuned by its sound master.

105 Watts per Channel, Backed by Denon's 70% Guarantee

Nine built-in amplifier channels are rated at 105 watts each (8 ohms, 20 Hz–20 kHz, 0.08%, two channels driven). Denon says its receivers deliver over 70% of rated output to up to five channels at the same time, so big movie scenes keep their impact.

Every Major 3D Sound Format

Dolby Atmos and DTS:X place sound around and above you. The AVR-X3900H also plays Auro-3D, IMAX Enhanced and 360 Reality Audio, which uses Sony's 360 Spatial Sound technology. Auro-Matic and DTS Neural:X can spread standard soundtracks across all your speakers.

Built to Expand

The receiver processes 11.4 channels but amplifies nine. Add a two-channel power amplifier to the 11.4 pre-outs and you can run 11 speakers. Four independent subwoofer outputs let you add bass where your room needs it.

Six 8K HDMI Inputs and Gaming Features

Denon lists all six HDMI inputs as 8K. The receiver supports 8K pass-through and upscales 4K content to 8K, with Dolby Vision, HDR10+, HLG, Dynamic HDR and HDCP 2.3. Variable Refresh Rate, Auto Low Latency Mode and AMD FreeSync keep gameplay smooth. An eARC HDMI output carries Dolby TrueHD, DTS-HD Master Audio and Dolby Atmos from your TV's apps.

Room Correction, With a Dirac Live Upgrade Path

A built-in suite of Audyssey room correction tools measures your room with the included microphone and tunes the system to it. For more control, the receiver is ready for an optional upgrade to Dirac Live room correction.

Whole-Home Sound with HEOS

HEOS is built in, controlled with the free HEOS app. Stream from your Spotify account or play from your phone over Bluetooth, and add Denon Home speakers to other rooms.

What It Needs in Your System

On its own, the AVR-X3900H powers nine speakers plus up to four powered subwoofers. For an 11-speaker layout, add a two-channel power amplifier. It has a moving magnet phono input, so an MM turntable connects directly.

It is 17.1 inches wide, 14.9 inches deep and 6.6 inches tall without the antennas, and weighs 27.6 pounds. With the antennas raised, it stands 9.3 inches tall, so check your shelf height and depth.

Who Is This Receiver Best For?

• You want a full Dolby Atmos system with height speakers — nine amplified channels, with 11.4 processing to grow
• You love deep, even bass — four independent subwoofer outputs
• You watch IMAX Enhanced or Auro-3D content — both are supported along with Atmos and DTS:X
• You game on a current console or PC — VRR, ALLM and AMD FreeSync on 8K inputs
• You still play records — a moving magnet phono input is built in
• Seven channels and two subwoofers are enough for you — the Denon AVR-X2900H costs less

How Does It Connect to Your System?

Connect your speakers to the speaker terminals and your subwoofers to the subwoofer outputs. Plug your sources into the HDMI inputs, then connect the eARC HDMI output to your TV's eARC port. To add channels, connect a power amplifier to the matching pre-outs.

Connect the receiver to your network to use HEOS. Place the included microphone at your listening position and run the Audyssey setup to tune the system to your room.

Pairs Well With

A receiver is the center of a home theater. These categories complete it.

• Speakers — front, center, surround and height speakers for your layout
• Subwoofers — up to four, using the independent subwoofer outputs
• Stereo Amplifiers — a two-channel amp adds the 10th and 11th channels
• Speaker Cables — to connect each speaker to the receiver
