The black Denon AVC-X4800H is a home theater amplifier designed to deliver a complete audiovisual experience. As the successor to the AVC-X4700H, it offers notable improvements in HDMI connectivity and audio performance.
The AVC-X4800H is equipped with 9 amplification channels, each delivering an impressive 125 W per channel (into 8 ohms, 20 Hz–20 kHz, 0.05% distortion, 2 channels driven). This configuration allows you to create a 9.4-channel system, providing a breathtaking three-dimensional sound experience.
The amplifier uses a monolithic design, where each amplification module is placed on a separate board. This approach significantly reduces crosstalk and vibrations, resulting in purer and more precise sound. In addition, the high-current amplifiers can drive low-impedance speakers, ensuring compatibility with a wide range of speaker systems.
The AVC-X4800H stands out for its enhanced HDMI 2.1 connectivity. With 7 HDMI inputs and 3 outputs, including two compatible with 8K/60 Hz and 4K/120 Hz, this amplifier is future-ready. It supports the latest HDR formats, including Dolby Vision, HDR10, HDR10+ and HLG, ensuring vivid and lifelike images.
Gamers will particularly appreciate features such as VRR (Variable Refresh Rate), QFT (Quick Frame Transport), ALLM (Auto Low Latency Mode) and FRL (Frame Rate Link). These technologies ensure a smooth and responsive gaming experience, eliminating screen tearing and latency issues.
The AVC-X4800H excels at multichannel audio processing. It supports the most advanced 3D audio formats, including Dolby Atmos, DTS:X and Auro-3D. The ability to configure up to four independent subwoofers allows for precise management of low frequencies, creating a rich and balanced sound experience.
The amplifier also incorporates surround virtualization technologies such as Dolby Atmos Height Virtualization and DTS Virtual:X. These features make it possible to simulate spatial sound even with more modest speaker configurations, delivering an immersive experience from standard stereo or multichannel sources.
To optimize sound performance according to your room, the AVC-X4800H is equipped with the Audyssey MultEQ XT32 calibration system. This technology analyzes the acoustics of your space and automatically adjusts various parameters to achieve the best possible sound.
In addition, the amplifier offers the option to add Dirac Live, an even more advanced acoustic calibration tool, available at an extra cost. This option allows the most demanding audiophiles to further refine the sound quality of their setup.
Thanks to built-in HEOS technology, the AVC-X4800H becomes the heart of a multiroom audio system. It allows you to stream music wirelessly throughout your home and access numerous music streaming services. Compatibility with AirPlay 2 and Bluetooth further expands streaming possibilities from your mobile devices.
The amplifier also supports high-resolution audio file playback, including ALAC, FLAC and WAV formats up to 24-bit/192 kHz, as well as DSD 2.8/5.6 MHz. Music lovers will appreciate the sound reproduction quality, whether listening to stereo music or using more complex multichannel configurations.
Despite its technical complexity, the AVC-X4800H is intended to be accessible thanks to its intuitive user interface. The setup assistant guides the user step by step for a hassle-free installation. The front-panel LCD screen and on-screen display make it easy to navigate the menus.
For those who prefer remote control, the Denon AVR Remote app offers a complete and user-friendly interface on a smartphone or tablet. It allows you to manage all the amplifier’s functions, from volume adjustment to source selection, as well as configuring advanced settings.
By registering your product, you can extend the manufacturer’s warranty to 3 years
Like the AVC-A1H, the Denon AVC-X4800H allows connecting four subwoofers via as many independent outputs, compared to two on the AVC-X4700H. Similarly, the DAC has been upgraded, with the AKM4458 replaced by a Texas Instrument PCM5102A (384 kHz/32-bit, 8 channels). The DSP is an Analog Devices ADSP-21593 Shark+ chip (same as in the AVC-A1H) and the capacitors have a capacity of 15,000 microfarads.
The main improvement lies in full HDMI 2.1 connectivity on all inputs and outputs, enabling support for 8K/60 Hz and 4K/120 Hz signals. In addition, the AVC-X4800H benefits from an improved monolithic amplification design, offering better sound quality.
Yes, the amplifier is compatible with Amazon Alexa, Google Assistant and Apple Siri voice assistants, allowing voice control of certain functions such as volume adjustment or source selection.
Absolutely. The AVC-X4800H has a preamplifier mode that disables the internal amplification section, allowing you to use the unit as a preamplifier/processor with external power amplifiers.
The system uses a supplied microphone to measure your room’s acoustic characteristics from several listening positions. It then automatically adjusts various parameters such as speaker levels, distances and equalization to optimize sound quality for your specific environment.
Yes, the amplifier allows you to configure up to three independent audio zones. This lets you play different audio sources in different rooms of your home simultaneously.
