The catch
Denon AVR-X4800H
7.1.4 calls for two external amplifier channels.
Side by side
X4800H fits a nine-speaker room, or a 7.1.4 plan where an external stereo amplifier is already on hand. X6800H is the pick for running 7.1.4 off one receiver or holding on to legacy composite and component video sources.
Before you buy
With X6800H you drop the separate stereo amplifier that X4800H needs for eleven speakers.
Where this comes from
7 + 4 makes eleven main channels. X4800H carries nine amplifiers, X6800H eleven.
The catch
7.1.4 calls for two external amplifier channels.
The catch
The chassis is 5.3 pounds heavier.

Denon X4800H vs X6800H on internally powered 7.1.4, external amplifier needs, legacy video connections and the load on a cabinet shelf.
X4800H fits a nine-speaker room, or a 7.1.4 plan where an external stereo amplifier is already on hand. X6800H is the pick for running 7.1.4 off one receiver or holding on to legacy composite and component video sources.
Which one fits
Eleven internal amplifiers come with X6800H.
The layout is powered by each, and each provides seven fast HDMI inputs.
The external pair is usable with X4800H. For this layout X6800H has no need of it.
A component input is included on X6800H, but not on X4800H.
In practice
With X6800H you drop the separate stereo amplifier that X4800H needs for eleven speakers.
7 + 4 makes eleven main channels. X4800H carries nine amplifiers, X6800H eleven.
Ratings of 140W against 125W come to about 0.49dB of theoretical electrical headroom.
10 × log10(140 ÷ 125) comes to approximately 0.49dB when load and test conditions are the same.
Despite the same published 17.1 by 15.3 by 6.6-inch envelope, the X6800H is 5.3 pounds heavier.
34.4 minus 29.1 comes to 5.3 pounds. Both measurements are taken with the antennas horizontal.

Handles your setup
Runs 5.1.2 on its own built-in amplifiers. Takes 3 HDMI devices, 1 of them at 4K/120Hz.

A powered subwoofer does not count toward the speaker channels. This checks one main room. Check Zone 2, bi-amping and unusual speaker assignments yourself. Leave room for ventilation, and confirm HDMI settings, cables and speaker impedance before you install.

Denon, AVR-X4800H
Seven fast HDMI inputs and four independent sub outputs come with this nine-amplifier receiver, which has eleven processing channels. It fits a big source collection and a possible external-amp expansion down the road.

Denon, AVR-X6800H
No extra power amplifier is needed to run 7.1.4, thanks to the eleven built-in amplifiers. Thirteen-channel processing, four independent sub outputs and extensive main-channel pre-outs give larger installations room to grow.
Spec by spec
| Spec | Denon AVR-X4800H | Denon AVR-X6800H | In practice |
|---|---|---|---|
| Built-in amplifiers and processing | 9 amplifiers, 11 processing channels | 11 amplifiers, 13 processing channels | X6800H drives 7.1.4 from its own amplifiers, and with extra amplification it can process larger documented systems. |
| Published two-channel power | 125W into 8 ohms | 140W into 8 ohms | The specification for each covers 20Hz to 20kHz at 0.05% distortion with two channels driven. |
| Analog audio inputs | 5 | 6 | Another analog source connection is available on X6800H. |
| Composite video inputs | 0 | 2 | Two composite-video sources can plug directly into X6800H. |
| Component video inputs | 0 | 1 | X6800H has room for one component-video source. |
| Receiver weight | 29.1 pounds | 34.4 pounds | The shelf has to carry 5.3 pounds more with the larger model. |
Trade-offs
Change of plan
Go with Denon AVR-X4800H. Either 5.1.4 or 7.1.2 can run on its nine internal amplifiers.
Go with Denon AVR-X6800H. The documented 7.1.4 layout is powered by its eleven internal amplifiers.
Neither model fits. Neither the documented processing layouts nor the internal-amplifier ones cover this requirement. Pick a receiver that has the physical configuration you need.
Decision guide
Go with X4800H if the room is nine speakers or you already own an external stereo amplifier for 7.1.4. Go with X6800H if you want 7.1.4 powered from one receiver or need to retain legacy composite and component video sources.
Running 5.1.4 directly on an X4800H uses all nine internal amplifiers, and adding a stereo amp lets it process 7.1.4. With eleven amplifiers, the X6800H keeps 7.1.4 a one-receiver installation. Thirteen-channel processing on it does not mean all thirteen channels are powered internally.
Two composite inputs and one component input are on the X6800H, and the X4800H leaves those legacy video connections out. An older console or player may make that matter. Check the source resolution and how the receiver converts it, instead of assuming every analog signal turns into every HDMI format. A rack that is all HDMI gains nothing from those sockets in connection terms.
In theoretical level terms the stereo power-rating gap is fairly small, and neither rating predicts eleven-channel output. Two additional amplifier channels are the more concrete difference. Both receivers share the same quoted chassis envelope, yet the X6800H weighs 5.3 pounds more. Check shelf loading and ventilation even if the space you have for the X4800H seems suitable.
