Ресиверы — Denon AVC-X4800H

The AVC-X4800H is a Denon home cinema receiver with 9.4 channels, 8K video support and the HEOS streaming platform inside. It carries nine power amplifiers, yet its processing reaches 11.4 channels, so two more speakers can be driven by an outboard stereo amplifier. The model sits below the AVC-X6800H in the Denon X-series receiver range.

Key specs that matter

Denon rates each channel at 125 W into 8 ohms from 20 Hz to 20 kHz at 0.05 % THD with two channels driven. Into 6 ohms at 1 kHz the figure rises to 165 W at 0.7 % THD with two channels driven, and to 200 W at 1 % THD with one channel driven. Seven HDMI inputs, all 8K-capable and including one on the front panel, sit alongside three HDMI outputs, one of which offers eARC. Four independent subwoofer outputs are provided. The chassis measures 434 x 389 x 167 mm without antennas and weighs 13.4 kg, and power consumption is 710 W in operation and 0.1 W in standby.

Engineering and use context

The HDMI 2.1 section handles 8K at 60 Hz and 4K at 120 Hz, with 8K pass-through, upscaling to 8K and a GUI overlay, plus HDCP 2.3. HDR support covers HLG, Dolby Vision, HDR10+ and Dynamic HDR. On the audio side the decoder handles Dolby Atmos, DTS:X Pro, Auro 3D and IMAX Enhanced, while DTS Neural X and DTS Virtual X handle upmixing. Audyssey MultEQ XT32 is built in and ships with a measuring microphone. Digital conversion uses 32-bit D.D.S.C. HD processing and a Clock Jitter Reducer, and there is a Pure Direct mode. The power section follows a mono block construction with discrete amplifiers. Three multi-room zones are supported with assignable speaker terminals, and the third HDMI output is dedicated to Zone 2 video. Network features include HEOS, AirPlay 2, Spotify Connect and TuneIn plus Qobuz, and Roon Tested certification is listed. File playback extends to DSD at 5.6 MHz and FLAC at 192 kHz, and Bluetooth can send audio out to headphones or speakers. The Denon AVR Remote app for iOS and Android controls the receiver, and an ECO mode plus auto-standby lower energy use. Amazon Alexa, Google Assistant and Apple Siri can issue voice commands, and ALLM, VRR and QFT are supported for game consoles.

Pairing

The 11.4 multichannel pre-out lets the owner hand the front channels or all channels over to separate power amplifiers while the internal amps drive the rest. Five analog inputs, two optical plus two coaxial jacks and a USB audio input take other sources, while a turntable plugs into the MM phono socket, and the four subwoofer outputs can each feed their own powered subwoofer.

Alternatives

The Denon AVC-X6800H is the next receiver up, with 11 power amplifiers, 13.4-channel processing and a higher power rating per channel.
