Ресиверы — Denon AVR-X2800H

The AVR-X2800H is a 7.2-channel Denon AV receiver with built-in HEOS streaming for several rooms, aimed at a home cinema that combines Dolby Atmos or DTS:X audio with 8K video sources. It carries seven discrete power amplifier channels and two dedicated subwoofer pre-outs, and it also covers stereo music through network streaming, Bluetooth and a turntable input.

Key specs that matter

Denon rates the amplifier at 95 W per channel into 8 ohm across 20 Hz to 20 kHz at 0.08% THD, 125 W into 6 ohm at 1 kHz, and 185 W into 6 ohm with a single channel driven. The HDMI section has six inputs, three 8K-ready, plus a pair of HDMI outputs, the first of them eARC-capable. The video section handles 8K at 60 Hz and 4K at 120 Hz, with pass-through of HDR, HLG, Dolby Vision, HDR10+ and Dynamic HDR under HDCP 2.3. Legacy audio inputs comprise four analog RCA pairs, two optical, one coaxial and an MM phono stage, and seven gold-plated screw-type speaker terminals are fitted. The chassis measures 434 x 340 x 168 mm without antenna and weighs 9.5 kg.

Engineering and use context

Besides Dolby Atmos and DTS:X, the processor offers Dolby Surround and DTS Neural X upmixing for older content, plus DTS Virtual X and Atmos height virtualization for rooms without overhead speakers. The 8K section supports signal pass-through, scaling and GUI overlay, and for consoles it passes VRR, QFT and ALLM, together with 3D pass-through and Auto LipSync. Through eARC a TV can send Dolby TrueHD, DTS HD Master Audio and Dolby Atmos back to the receiver, while plain ARC is limited to conventional 5.1 formats or PCM. The built-in Bluetooth works as a transmitter as well, so one pair of wireless headphones can play alongside the speakers at the same time. A front USB port reads files from a drive. Streaming options include Spotify Connect, Pandora, SiriusXM, TuneIn and AirPlay 2, and the unit is Roon Tested. The receiver responds to voice commands through Alexa, Google Assistant or Apple HomePod. With a pair of speakers in a second room, the main room can run 5.1 surround while the other area plays a separate source, and that zone can be fed from HDMI, optical, coaxial, network, USB or analog sources, and integrators can use IP, RS-232 and web control. Rated consumption is 500 W in operation and 0.1 W in standby.

Pairing

Multichannel pre-outs at 0.2 V are provided, so an external power amplifier can take over some channels. With its two sub pre-outs, the unit can drive twin powered subwoofers in a 5.1.2 or 7.1 layout. The RC-1253 remote and Quick Select Plus memory presets handle daily operation.

Alternatives

Denon's AVR-X3800H is a larger X-Series receiver with 9.4 channels for systems that need more speakers.
