DESIGN & BUILD
The unit features discrete high-current amplifiers on all channels with low-impedance drive capability, but the difference we get this time around is in its Monolithic Amplifier layout. This means that compared to the X4700H that used two boards for 5 channels and 4 channels each, the new X4800H is using an independent power amplifier board for each channel instead which means less crosstalk and less vibration.
the X4800H has more features compared to the X3800H and one of them is AL32 processing. AL32 Processing, a Denon proprietary analog waveform reproduction technology, supports up to 192 kHz sampling frequency and 32bit expansion on your receiver. The technology thoroughly suppresses noise associated with D/A conversion to reproduce low-level signals with optimum clarity and bring out all the delicate nuances of the music. AL32 Processing Multi-Channel means the technology is applied on all channels and all input sources.
For X4800H , Denon is using their D.D.S.C. -HD32 technology. This stands for Dynamic Discrete Surround Circuit and means that all stages in the audio processing are discrete and not combined chipsets. This way Denon can select exactly the components they want in order to produce the audio output they desire.
Lastly the X4800H comes with a Clock Jitter Reducer. If there is jitter in the clock that serves as the reference for D/A conversion, the reproduced waveform will be blurred and an accurate sound cannot be produced. The Clock Jitter Reducer compares the phase of the input and output signals to reduce jitter.
AUDIO
A new addition of MPEG-H codec which has started to be used extensively for broadcasting. It is already being used with ATSC 3.0 in South Korea and over DVB in certain European countries while it is used in several streaming services for powering their 360 Reality Audio music. So from the looks of it the MPEG-H format will become more and more popular over the coming years making the X4800H completely future proof in this regard.
In addition, the X4800H has the ability to drive four subwoofers independently instead of two that was previously possible. As such the inclusion of four outputs allows for immense control over the kind of setup you want to create.
With such an AV receiver there is not much more to say when it comes to its cinematic excellence. The X4800H was perfect in all kinds of material, either it was a delicate calm scene or all out destruction. Whether it was its front performance, surround accuracy, Atmos clarity or bass prowess, the X4800H had them all.
