Selected Features

Amplifier

Denon AVR-X6300H has 11 channel and Onkyo TX-SR343 has 5 channel amplifiers. Denon AVR-X6300H delivers 140 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and Onkyo TX-SR343 delivers 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and they both have stable performance at 4 Ω load.


Video Features

Both receivers support 4K passthrough up to 60p. Denon AVR-X6300H can do 4K upscaling up to 60p. Denon AVR-X6300H supports HDR10, Dolby Vision.


HDR10

High-dynamic-range (HDR) video has greater dynamic range than standard-dynamic-range (SDR) video with brigter whites and deeper blacks. HDR10 was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports up to 1000 nits of brightness and 10-bit color which corresponds to 1024 shades of the primary RGB colors.


Dolby Vision

Dolby Vision is an update to HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to 10,000 nits maximum brightness on a scene-by-scene or frame-by-frame basis and supports up to 12-bit color depth (4096 shades of RGB) and 8K resolution.


Dolby Atmos and Dolby Surround upmixer

Denon AVR-X6300H supports Dolby Atmos with its Dolby Surround upmixer. It can be configured upto 7.1.4 channels using internal amplifiers.

Dolby Atmos is the first cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound - the helicopter, a car screeching around a corner, a melodic bird call - can exist as an independent audio object, free of channel restrictions. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. You'll feel like you're inside the action, in ways you've never experienced before.

Dolby Atmos for the home represents every sound in the original cinema mix as an audio object. Extensions to the Dolby Audio™ codecs, along with an advanced scalable algorithm, allow Dolby Atmos to be delivered via Blu-ray Disc and streaming media. A spatially-coded substream is added to Dolby TrueHD or Dolby Digital Plus. A Dolby Atmos audio/video receiver (AVR) adapts the cinema experience to your home theater from seven speakers to as many as 34 in 24.1.10 configuration, recreating the original artistic concept. The format supports up to 128 simultaneous independent audio objects in a mix for rich, realistic, and breathtaking sound. It recreates the director's original concept through descriptive metadata to provide customized playback for home theater and delivers sounds above you through overhead speakers, special upward-firing Dolby Atmos speakers, or a Dolby Atmos enabled sound bar.

If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.


DTS:X and Neural:X upmixer

Denon AVR-X6300H supports DTS:X. It can be configured upto 7.1.4 channels using internal amplifiers.

A technique used in DTS:X is similar to the one used in Dolby Atmos. Instead of a fixed number of channels, DTS:X defines object locations from the listener in polar coordinates. An a/v receiver then dynamically renders sound according to the current speaker configuration. The speaker layout employed by DTS:X is the sum of Dolby Atmos and Auro-3D. It has standard 7.1 channel base layer, a 5 channel height layer above the base layer on the front and side walls, and 3 rows of speakers on the ceiling.

DTS Neural:X is an upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.


Auro-3D with its Auro-Matic upmixer

Denon AVR-X6300H supports Auro-3D and its Auro-Matic upmixer via charged firmware upgrade. Auro-3D is an immersive 3D audio format developed by the Belgium-based company Auro Technologies. It consists of three layers of sound - surround, height and overhead ceiling. The base horizontal layer uses 5.1 or 7.1 format, the height layer is on top of the base layer and its information is extracted from the standard 5.1 surround PCM carrier. The a/v receiver decoder then extracts this information during playback. In home cinema Auro-3D comes with different listening formats - Auro 9.1, Auro 10.1 with added Top Ceiling channel ("Voice of God"), Auro 11.1 with added Front Height Center channel, and Auro 13.1 with added Left Rear Surround & Right Rear Surround channel. Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.


WRAT

Onkyo TX-SR343 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.


D.D.S.C.

Denon AVR-X6300H has D.D.S.C (Dynamic Discrete Surround Circuit). A single IC chip is generally used in processing A/D, DSP, and D/A conversions that are vital to sound quality. The D.D.S.C. uses separate components to process the important sections of the A/D, DSP, and D/A conversions and therefore significantly improves signal processing capability and performance. In addition, the approach of developing and incorporating high-quality dedicated elements in the sections that configure the circuitry makes it easier to develop a high-grade, advanced surround circuit compared with the method where all processing is concentrated within a single chip. Denon’s proprietary digital audio technology that had for many years been developed for pure Hi-Fi components is now also alive in each block of the D.D.S.C.


Advanced Music Optimizer

Compressed music enhancement in Onkyo TX-SR343 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.


Phase-Matching Bass Boost

Onkyo TX-SR343 features Phase-Matching Bass Boost. The negative effects of phase-shift or the timing difference between sound waves of different frequencies can sometimes be heard in audio players when corners are cut in order to increase bass response. While most audio systems have some form of low-frequency enhancement system, often a bigger bass sound comes at the expense of mid-range clarity, and results in a smeared or muddy sound. Onkyo’s Phase-Matching Bass Boost technology avoids this problem by improving the phase timing to preserve the natural clarity of the mid-range allowing vocals and strings to shine while maintaining a smooth, powerful bass response at all volume levels.
