Denon AVR-X4800H - Black

Description

9 × 125 W Amplification and 11.4-Channel Processing

The AVR-X4800H amplifies 9 channels at 125 W per channel into 8 ohms (20 Hz-20 kHz, THD 0.05%, two channels driven) and processes up to 11.4 channels in total. An 11.4-channel pre-out lets you add an external power amplifier to drive the two extra channels (for example a 7.4.4 or 5.4.6 configuration). It decodes Dolby Atmos, DTS:X, Auro-3D, and IMAX Enhanced, with Auro-Matic, Dolby Surround, and DTS Neural:X for upmixing non-native sources. 

HDMI 2.1 (8K on All 7 Inputs, 4K/120 Hz)

All 7 HDMI inputs are HDMI 2.1 and support 8K up to 60 Hz, 4K up to 120 Hz, HDCP 2.3, HDR10, HDR10+, Dolby Vision, HLG, and Dynamic HDR. VRR, ALLM, and QFT are supported for recent consoles (PlayStation 5, Xbox Series X). Two of the three HDMI outputs are 8K-capable, and one supports HDMI eARC to receive Dolby Atmos and DTS:X streams from a modern TV's built-in apps.

Audyssey MultEQ XT32 with Dirac Live Compatibility

The AVR-X4800H includes Audyssey MultEQ XT32 with Dynamic EQ and Dynamic Volume, measured via the supplied microphone. It is also compatible with Dirac Live Room Correction: the Dirac Live license is purchased separately and installed online, then replaces Audyssey for room correction. Four independent RCA subwoofer outputs allow separate delay, level, and equalization per output.

HEOS Built-In, MM Phono, and Multi-Zone

On the streaming side, HEOS Built-In gives direct access to Spotify Connect, TIDAL, Amazon Music, Deezer, TuneIn, and Roon; Apple AirPlay 2 and Bluetooth are supported, along with dual-band Wi-Fi and an Ethernet port. A rear-panel MM phono input is included for a turntable. The receiver has a Zone 2 stereo line output and multi-zone control; the 11 speaker binding posts are assignable and support bi-amp mode or reassignment to a second zone. A front USB port plays high-resolution files up to 24-bit/192 kHz (MP3, WMA, WAV, AAC, FLAC, ALAC).

Common Questions

What's the difference between 9-channel amplification and 11.4-channel processing?

The built-in amplifier drives up to 9 passive speakers directly from the rear binding posts. The processor can handle up to 11.4 channels through the pre-outs: the two extra channels are sent as line-level signals and connect to an external power amplifier (for example, to go from a 7.1.2 to a 7.1.4 Dolby Atmos layout).

Does the AVR-X4800H support Dirac Live?

Yes. It is compatible with Dirac Live Room Correction (upgrade via a license purchased separately from Dirac). Once activated, the Dirac license replaces Audyssey MultEQ XT32 for room correction. Note that the AVR-X4800H does not include Dirac Live Bass Control; that feature is reserved for the higher-tier Denon models (X6800H, A10H).

How many subwoofers can be connected, and how independently?

The AVR-X4800H has four independent RCA subwoofer outputs. Each output can carry its own delay, level, and equalization, allowing a multi-subwoofer setup to smooth low-frequency response across the room.

How do the HDMI inputs handle 4K/8K video and gaming?

All 7 HDMI inputs are HDMI 2.1: they pass 8K up to 60 Hz, 4K up to 120 Hz, HDCP 2.3, HDR10, HDR10+, Dolby Vision, HLG, and Dynamic HDR, and they support VRR, ALLM, and QFT for recent consoles (PlayStation 5, Xbox Series X). Two of the three HDMI outputs are 8K-capable, and one supports HDMI eARC to receive Dolby Atmos and DTS:X streams from a modern TV's apps.
