  • "User Mode"-Speicher

    Die leicht zugänglichen "User Mode"-Tasten auf der Frontplatte des Gerätes und auf der Fernbedienung ermöglichen das Abspeichern und den schnellen Abruf benutzerdefinierter Einstellungen wie Quelle, Eingangs-Modus und Auto Surround-Modus. Die Speicher können für die Hauptzone und die Zone 2 separat belegt werden.

  • Audyssey DSX

    This new technology extends 5.1- and 7.1-channel sound sources to a wider and higher dimension considering the human perception that is usually focussed on the front. A more spacious sound is
    achieved through a pair of wide speakers placed wider than the usual front speakers, and
    a greater sense of height in sound is achieved by adding two height speakers above the

  • Auto Surround

    Auto Surround ist eine Ergänzung zum bewährten Personal Memory Plus, das unter anderem den favorisierten Surround-Modus für jeden Eingang individuell speichert. Dank Personal Memory Plus entfällt für DENON-Kunden bereits seit Jahren das lästige Umschalten des Surround-Modus, wenn auf eine andere Quelle umgeschaltet wird. So wechselt der Receiver beispielsweise automatisch von „Dolby Surround“ auf „Stereo“, wenn der Eingang von VCR (Videorecorder) auf Tuner (Radio) gewechselt wird. In Verbindung mit dem neuen Auto Surround wird nicht nur der zuletzt verwendete Surround-Modus pro Eingang (Personal Memory Plus) gespeichert, sondern das Gerät kann auch zusätzlich nach Eingangssignal differenzieren. Unterschieden wird zwischen (1) Analog und PCM Stereo, (2) Bitstream 2-Kanal (Dolby Digital, DTS) und (3) Bitstream Mehrkanal. Diese neu entwickelte Automatik ist besonders bei DVD hilfreich, da DVD-Player eine Vielzahl von Medien und Formaten wiedergeben. Anhand des Eingangssignals kann der DENON-Receiver bzw. Verstärker auf das eingelegte Medium schließen und automatisch den optimalen Surround-Modus aktivieren. Zum Beispiel wird bei eingelegter CD (Stereo, PCM) sofort der ideale „Dolby Pro Logic II Music“-Modus gewählt, bei älteren Filmen auf DVD im alten „Dolby Surround“-Format (Dolby Digital 2.0) oder auch DVD-Menüs liefert „Dolby Pro Logic II Cinema“ optimale Ergebnisse und aktuelle Filme in 5.1 (Dolby Digital, DTS) werden automatisch richtig in „Dolby Digital 5.1“ bzw. in „DTS 5.1“ decodiert. Trotz der Vielzahl von Tonformaten und Wiedergabemodi bleibt die Bedienung entsprechend ausgestatteter DENON-Surround-Geräte einfach und komfortabel.

  • Cinema Equalizer

    The sound from movie sources recorded in Dolby Digital, DTS, or other formats emphasizes high-frequency range due to a theater’s front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range is too strong. Denon amplifiers feature a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to. (For Dolby Digital, Dolby Pro Logic II, and DTS surround modes.)

  • Compressed Audio Restorer

    The Compressed Audio Restorer ensures that even the now widely used, data-compressed audio files can properly do with music and lots of fun.

    enable a precise signal analysis of medium frequency locations and sophisticated computational procedures are Denon components equipped in the situation, residual harmonic content of conventional MP3, WMA or AAC signals to evaluate, missing bass back and height proportions, and so again to produce a full music signal. The spatial image, the dynamics improved. Even the often-ailing bass is back to its former strength. This is not technically sophisticated reconstruction of the audio signal Restorers can compare with the conventional arrangements are sound

  • DLNA Certified

  • Dolby Pro Logic IIx

    Dolby Pro Logic IIx is an extension of Dolby Pro Logic II technology. This highly sophisticated algorithm processes native stereo and 5.1 channel content to produce 6.1 or 7.1 output channels. And Dolby Pro Logic IIx is not available in the system without surround back speaker(s).

    Dolby Pro Logic IIx Music: The music mode creates a rich and enveloping surround ambience delivered to the subwoofer, optimizing the visceral of planned rear effects. This mode can only be used with 2-channel audio sources.

    Dolby Pro Logic IIx Cinema: The Cinema mode is optimized for movies or programs with Dolby Surround soundtracks. This mode is also appropriate for use with video game.

  • Dolby TrueHD

    Dolby TrueHD is a completely loss-free Audio-Codec for high resolution audio for up to 8 channels Supporting 24-Bit and sampling rates up to 192 kHz. It requires specific Dolby HD decoders. Since the resulting signal is bit-to-bit to the master you can achieve the ultimate in audio quality.

  • DTS-Decoder

    A data compression method developed by Digital Threater Systems that takes six channels of audio (5.1) and folds them into a single digital bitstream. This differs from Dolby Digital in that the data rate is a somewhat higher 1.4 Mbs, which represents a compression ratio of about 4 to 1.In order to take advantage of this DVD feature, a DTS decoder is required. DTS decoders are installed internally in Denon players and A/V recievers.

  • HDCD-Decoder

    HDCD-encoded CDs are encoded with 20 bits of real musical information, as compared with 16 bits for all other CDs. HDCD overcomes the limitation of the 16-bit CD format by using a sophisticated system to encode the additional 4 bits onto the CD while remaining completely compatible with the existing CD format. HDCD provides more dynamic range, a more focused 3-D soundstage, and extremely natural vocal and musical timbre. With HDCD, you get the body, depth, and emotion of the original performance not a flat, digital imitation.

  • Made for iPod

  • HDMI-output (HDCP)

    HDMI (high definition multimedia interface), a new connector that bases itself on the DVI-HDCP model. HDMI supports uncompressed high definition video plus multi-channel audio in a single cable using a smaller connector that eliminates the need for multiple cables in home entertainment systems, simplifying installation and eliminating cross technology confusion. It transmits uncompressed digital video so that the picture maintains a high quality of color depth, brightness and contrast. It also supports Consumer Electronics Control (CEC) based on the AV.link protocol so it can be controlled with a universal remote that is used with multiple HDMI sources such as Denon DVD players. HDMI supports bi-directional coommunciation between devices, allowing DVD players to communicate with Plasma's, LCD screens and Projectors, as long as they are HDCP compatible.
    The HDMI connection supports every uncompressed standard, enhanced and high definition video format ranging from 480I to 480P, 720P, 1080I and 1080P as well as existing PAL formats. It also has the bandwidth to support compressed audio formats such as Dolby Digital, Dolby Digital EX, DTS, DTS EX and uncompressed formats (PCM audio) up to eight channels, up to 192kHz, up to 24-bits.

    High Definition Multimedia Interface(HDMI) and High Definition Content Protection (HDCP) is a copyright protection system installed on most Plasmas, LCD's and projectors consisting of a HDMI or DVI input. All Denon DVD players require HDCP compliant displays to be fully compatible. It prohibits the copying of copyrighted material, like onto a VCR or DVD-recorder.

  • Audyssey MultEQ Pro Calibration

    Audyssey Registered Installers can provide advanced room equalization with MultEQ XT installed with the Audyssey Installer Kit and MultEQ Pro Software. The Audyssey Installer Kit comes with professional, pre-calibrated tools for the most accurate room measurements. MultEQ Pro Software allows more room measurements and the most precise room correction. It is possible to calibrate a home theater to standardized target sound curves and set speakers to appropriate level trim, distance and subwoofer crossover settings.

    MultEQ Pro offers up to 32 calibration measurements throughout the room using a professionally calibrated microphone. With your installer you can custom edit the target curve including midrange compensation. Moreover improved crossover optimization provides better blending between subwoofer and satellites.

    Not only will you here the astonishing results of the professional room calibration but you will also get a certificate that illustrates the results before and after the correction.

  • DTS-HD

    DTS-HD (High Definition) is a progression of DTS for high performance audio supporting upto 8 channels with a resolution of 24-Bit and sampling of upto 192 kHz. The differences between the formats is as follows:

    DTS-HD High Resolution Audio
    This format works like DTS however it uses a more effective compression algorithm, offering greater compression, the result is an audio signal almost bit for bit to the master while requiring a smaller amount of data.

    DTS-HD Master Audio
    This format is completely lossless with only minimal compression. The resulting audio signal is bit-for-bit to the master giving you the optimum in audio quality.

    A/V-Receivers with this logo can decode both formats, BD- or HD-DVD-Players with this logo can either decode or output the DTS-HD signal via HDMI.

  • Advanced AL32 Processing

    Advanced AL32 Processing, the new generation of the Alpha processor. It is capable of digital signals to expand not only in the resolution to 32 bits, but also leads an upsampling of the digital signals by up to 192 kHz.

    The Alpha processor suppresses quantization and disturbing are the finest musical nuances, even in extremely quiet passages of music, again, of course. Thus, for example as well as conventional 16-bit CDs in 32-bit quality of service and with an extended frequency range kHz up to 80. The downstream high-quality 32-bit, 192 kHz-D/A-Wandler the latest generation ensure the faithful conversion of the signals in the analog world.

    Advanced AL32 Processing The variation in multi-channel multi-channel devices to work simultaneously for all channels and smoother in operation for multi-fidelity sound reproduction.

  • Audyssey MultEQ-XT 32

    ​MultEQ XT32 is Audysseys most accurate room correction solution with more than ten thousand individual control points allowing finer details of the room’s problems to be captured and corrected. The ultra high resolution filters are applied to all channels including the subwoofers, with the most obvious benefit being heard in the low frequency range where correction is needed the most.

  • DTS-Neo:X

    ​This technology extends 2.0/5.1/7.1 sound sources to a wider and higher dimension considering the human perception that is usually focussed on the front. A more spacious sound is achieved through a pair of wide speakers placed wider than the usual front speakers, and a greater sense of height in sound is achieved by adding two height speakers above the front.

  • 3D Signal Pass Through

    3D HDMI video signals from Blu-ray players, set top boxes or game consoles are passed through the unit without processing. As part of HDMI 1.4 specification, this ensures that you can enjoy 3D programs without compromises in audio quality.
