Amplifier

Denon AVR-X4100W Marantz SR6015

7 channel Amplifier: Denon AVR-X4100W features 7 channel power amplifier. It is rated at 125 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

9 channel Amplifier: Marantz SR6015 features 9 channel power amplifier. It is rated at 110 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

  • Current Feedback Topology: Marantz SR6015 features Current Feedback Topology which is a well known, Marantz’ original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.
  • HDAM (Hyper Dynamic Amplifier Module): Marantz SR6015 features exclusive Marantz HDAM (Hyper Dynamic Amplifier Module) technology found on their Reference Series components. Marantz developed its own discrete circuit boards to replace standard IC's. These HDAM's consist of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound. Over the years Marantz developed different types of the HDAM to improve quality and to fit to the special requirements of a product category like CD or amplifier.

Speaker Configurations

Denon AVR-X4100W's and Marantz SR6015's amplifiers can be assigned for different speaker configurations.

  • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
  • Denon AVR-X4100W: 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier.
  • Marantz SR6015: 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
  • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
  • Denon AVR-X4100W: Not supported.
  • Marantz SR6015: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
  • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
  • Denon AVR-X4100W: 5.2, 7.2 with internal amplifier and 9.2 with addition of external 2 channel amplifier.
  • Marantz SR6015: 5.2, 7.2 with internal amplifier.
  • Front Wide Channel support: With the presence of two front wide speakers you can enhance the front surround stage. The following speaker configurations are available for front wide channels:
  • Denon AVR-X4100W: 9.2.
  • Marantz SR6015: Does not support.
  • 2-ch Bi-Amp: Both models are able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

  • Dolby Atmos

    Denon AVR-X4100W and Marantz SR6015 support Dolby Atmos. It is a cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound 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. 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.

    • Dolby Surround Upmixer: Both models support Dolby Surround Upmixer. 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.
    • Dolby Atmos Height Virtualization: Marantz SR6015 supports Dolby Atmos Height Virtualization which is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

    DTS:X

    Marantz SR6015 supports DTS:X. 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: Marantz SR6015 features DTS Neural:X which is an advanced 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.
    • DTS Virtual:X: Marantz SR6015 features DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
    • DTS Dialog Control: Marantz SR6015 has DTS Dialog Control. This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

    Auro-3D

    Denon AVR-X4100W supports Auro-3D. It 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: Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.

    Audyssey DSX

    Denon AVR-X4100W supports Audyssey DSX which allows you to augment a standard five-channel home theater with either two Front Wide or two Front High speakers. The Wide channels create an expansive soundstage and bring out convincing directional effects. Alternatively, Height channels can add a vertical dimension to movie and game soundtracks.


    Enhanced Audio Return Channel (eARC)

    Marantz SR6015 supports Audio Return Channel (ARC) feature allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.



    Sound Processing

    • Audyssey: Both receivers come with Audyssey Dynamic EQ, Dynamic Volume, LFC and Sub EQ HT.
    • Dynamic EQ: selects the best possible frequency response and surround volume levels moment-by-moment. This ensures that the bass response, tonal balance and surround impression remain constant despite changes in volume. This is the first technology that carefully combines information from incoming source levels with actual output sound levels in the room, a pre-requisite for delivering a dynamic volume solution.
    • Dynamic Volume: Your Listening experience can be greatly diminished when there are significant shifts in volume between television programs, commercials and within the program material itself. When this happens you must constantly adjust the volume to maintain your desired listening level. Audyssey Dynamic Volume monitors the volume of program material moment-by-moment and automatically adjusts it, maintaining the desired listening level for all content while optimizing the dynamic range to preserve impact.
    • LFC (Low Frequency Containment): While high frequencies are easily stopped by walls low frequencies pass right through. After identifying the frequency range that most readily passes through walls Audyssey developed a technique, called Audyssey LFC (Low Frequency Containment) that reduses the volume at those frequencies and applies psychoacoustic processing to restore the perception of low bass for listeners in the room. The result is no more angry neighbors and no loss of enjoyment for listeners.
    • Sub EQ HT: Placing two subwoofers in the room can cause problems, they can create standing waves or even cancel each other out resulting in even less bass than a single sub can produce. Audyssey Sub EQ HT allows two subwoofers to be properly used in a home theater system. The process is automated and takes only a few minutes. The result is rich, full bass for everyone in the room.
    • D.D.S.C. (Dynamic Discrete Surround Circuit): Denon AVR-X4100W has 24-bit D.D.S.C. 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.
    • ALPHA Processing: Denon AVR-X4100W has AL24 Processing.
    • AL24 Processing is analog waveform reproduction technology that represents a further advancement over Denon’s Adaptive Line Pattern Harmonized Algorithm Processing that won high acclaim for its exceptional sound quality. It has not only further reduced quantization noise but also supported the higher numbers of bits and sampling rates that have been drawing attention in next-generation media. To achieve audio output of 24-bit quality, AL24 Processing generates low-order 8-bit data by doubling the processing circuitry of the low-order data generator and processing the data internally, and then adds the 16 high-order bits. AL24 Processing interpolates the signal that was lost when the original sound was recorded as digital data so that it can faithfully reproduce the smooth analog waveform that existed prior to recording. AL24 Processing supports not only 16-bit but also 18-, 20-, and 24-bit digital input. With AL24 Processing, it is now possible to actually hear the delicate low-level resonances of music that had been absorbed by the concert hall and were difficult for conventional systems to reproduce.
    • Compressed Music Enhancer: Denon AVR-X4100W and Marantz SR6015 feature Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
    • MDAX2: Compressed music enhancement in Marantz SR6015 is done by Marantz’ MDAX2 technology. The use of compressed audio files like MP3, Windows Media™ Audio or AAC is getting more and more popular. The audio quality of these compressed files however is less than the original lossless files that are on a CD, especially lacking the higher frequencies and affecting the lower frequencies which make the audio image less wide and deep. The Marantz Digital Audio Expander 2, also called M-DAX2, recalculates the outputted frequency range. This enables you to get a more detailed and clearer sound.

    Room Calibration

    Denon AVR-X4100W comes with Audyssey MultEQ XT32 + PRO and Marantz SR6015 comes with Audyssey MultEQ XT32 room correction system.

    • Audyssey Room Calibration: Audyssey is an acoustic measurement technology which automatically restores the acoustic distortion caused by the acoustic behaviour of a room with only a push on a button. Audyssey equalization provides an clear, accurate, natural sound with voices and dialog that become focused and intelligible, restoring the musical balance. Musical instruments and sound effects become precisely localized and the surround soundstage is made seamless and enveloping.

Video Section

HDMI

Denon AVR-X4100W comes with 8 HDMI inputs. It has 3 outputs - 2 for MAIN and 1 for ZONE2.

Marantz SR6015 comes with 1 HDMI 2.1 input with 8K support and 6 inputs with 4K support. It has 3 outputs - 2 x 8K for MAIN and 1 x 4K for ZONE2.

  • Analog To HDMI Upconversion: Both receivers support analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
  • BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on Marantz SR6015 only).
  • HDCP Copy Protection: Denon AVR-X4100W is HDCP 2.2 and Marantz SR6015 is HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
  • Quick Media Switching (QMS): With HDMI 2.1a, Quick Media Switching for movies and video uses the HDMI VRR mechanism to eliminate the blackout period when an HDMI Source device switches its video mode. As long as the resolution remains the same and only the frame rate changes, QMS will instantly switch between frame rates. QMS eliminates A/V blackouts by using VRR technology to change frame rates, allowing instant changes from 24Hz to 60Hz frame rate, and anywhere in-between. The viewer never sees blank screens and gets a seamless experience (available on Marantz SR6015 only).
  • 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Denon AVR-X4100W does not support HDR.

Marantz SR6015 supports HDR10, HDR10+, Dolby Vision, Dynamic HDR and Hybrid Log-Gamma.

High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.

  • HDR10: HDR10 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 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.
  • HDR10+: HDR10+ is an HDR video technology that adds dynamic metadata to HDR10 source files. The dynamic metadata are used to adjust brightness levels on a scene-by-scene or even frame-by-frame basis. HDR10+ supports maximum of 10,000 nits peak brightness and 10-bit or more (up to 16-bit) color bit depth. It uses Samsung's dynamic metadata defined in SMPTE ST 2094-40.
  • Dolby Vision: Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. Like HDR10+, it includes dynamic metadata that are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way specified by the content creator. Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020. It uses Dolby's proprietary dynamic metadata defined in SMPTE ST 2094-10.
  • Dynamic HDR: Dynamic HDR enables a noticeable progression in overall video image quality from SDR to static HDR, and now static HDR to dynamic HDR. Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast, and wider color gamuts - on a scene-by-scene or even a frame-by-frame basis. HDR-enhanced content is available for movies, videos, TV shows, video and PC games and VR.
  • Hybrid Log-Gamma (HLG): The Hybrid Log-Gamma (HLG) is a transfer function developed mainly for HDR live video feed and over-the-air broadcasts. It is an HDR format that uses BT.2020 color primaries and a bitdepth of 10-bit. It is backward compatible with the transfer function of SDR and is designed to be better-suited for television broadcasting, where the metadata required for other HDR formats is not backward compatible with non-HDR displays. HLG defines a non-linear optical-electro transfer function, in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve.

IMAX Enhanced

Marantz SR6015 is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

  • What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.
  • IMAX Enhanced Content: IMAX Enhanced studio partners have announced IMAX Enhanced versions of movies that exclusively feature IMAX's signature picture, sound and scale.
  • Picture: Stunning, ultra-vivid 4K HDR picture that utilizes the newest, proprietary Digital Media Remastering technology (DMR) developed by IMAX. DMR accurately reduces noise and grain under the filmmaker’s guidance to best optimize the content for a much higher-quality, higher-brightness display. Without this technology, high-dynamic range content can actually look worse than what was originally seen and intended by the filmmaker.
  • Sound: IMAX and DTS have partnered with award-winning Hollywood sound mixers leveraging DTS:X codec technology integrated in home audio equipment and select televisions to deliver an IMAX signature sound experience with deeper bass and more dynamic range.
  • Scale: Select IMAX Enhanced titles that were shot with IMAX-certified cameras or specially formatted for IMAX theatres feature its exclusive expanded aspect ratio, enabling viewers to see the full scale and scope of the picture on 4K HDR TVs.
  • Streaming Services: IMAX Enhanced is now available on the world’s biggest streaming services, including Disney+, BRAVIA CORE, Tencent, iQiyi and more.

Gaming Features

Denon AVR-X4100W supports Auto Low Latency Mode (ALLM) Marantz SR6015 supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.

  • Auto Low Latency Mode (ALLM): Auto Low Latency Mode enables the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity. When the receiver detects a gaming signal it will enter ALLM. The signal will also be sent to the TV causing it to automatically switch to a low-latency, low-lag mode for gaming. Some functions will not be available on the receiver and TV during ALLM.
  • Variable Refresh Rate (VRR): VRR enables a gaming source such as a console or computer to deliver video frames as fast as it can, which in many cases is slower than the normal static refresh rate. It allows the TV to adapt to certain frame rate which reduces or eliminates lag, judder and frame tearing for more fluid and better detailed gameplay.
  • Quick Frame Transport (QFT): QFT reduces latency for smoother no-lag gaming, and real-time interactive virtual reality. It transports each frame at a higher rate to decrease display latency, which is the amount of time between a frame being ready for transport in the GPU and that frame being completely displayed.

Inputs and Outputs

Audio

  • 7.1 Multichannel Input: In case you have a high quality Blu-Ray or a DVD player with multichannel analog outputs you may connect it to a 7.1 multichannel analog inputs of Marantz SR6015 and use high quality DACs of the player instead of the ones in the receiver.
  • Analog Pre-Outs: Denon AVR-X4100W has 13.2 and Marantz SR6015 has 11.2 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, Denon AVR-X4100W has 9 channel processing but has only 7 channel amplifier and Marantz SR6015 has 11 channel processing but has only 7 channel amplifier, so they need external amplifiers connected to their analog pre-outs in order to reach their maximum speaker configurations.
  • Analog Line Inputs: There are 6 pair of line inputs on Denon AVR-X4100W and 5 pair of line inputs on Marantz SR6015 for connecting sources with analog outputs.
