    Audio Features

    Preamp/Processor Advantage: Delegating the amplification duties to a separate component allows the Marantz AV7705 surround preamplifier to keep a healthy distance between noise-inducing high voltage/high current circuits and sensitive low-level circuits. This means that the radio frequency and electromagnetic interferences that are found in most AV receivers simply don't exist in a preamplifier/processor, or are reduced by several orders of magnitude. The result is less distortion and less signal degradation in general.

    Balanced & Unbalanced Preamp Outputs: The Marantz AV7705 surround sound preamplifier features both balanced (XLR) and unbalanced (RCA) preamp outputs. Both the balanced XLR and unbalanced RCA outputs feature gold-plated connections for excellent signal transfer.

    • 11.2Ch Balanced XLR Preamp Outputs: If your power amplifier is equipped with balanced XLR inputs, then use the AV7705's balanced XLR preamp outputs. The AV7705's 11.2ch balanced XLR preamp outputs consist of Front L/R, Center, Surround L/R, Surround Back L/R, Height 1 L/R, Height 2 L/R, Subwoofer 1, and Subwoofer 2 (the dual subwoofer outputs are discrete). Balanced connections guard against induced noise and allow long cable runs without compromising sound quality. When connecting the AV7705 to a power amplifier via XLR, please make sure the pin-out configuration of the amplifier is the same as the preamplifier (Pin 1-Ground, Pin 2-Hot, Pin 3-Cold).
    • 11.2Ch Unbalanced RCA Preamp Outputs: If your power amplifier is not equipped with balanced XLR inputs and only offer unbalanced RCA inputs, then use the AV7705's unbalanced RCA preamp outputs. The AV7705's 11.2ch unbalanced RCA preamp outputs consist of Front L/R, Center, Surround L/R, Surround Back L/R, Height 1 L/R, Height 2 L/R, Subwoofer 1, and Subwoofer 2. The dual subwoofer outputs are discrete.
    Note: The Marantz AV7705 Surround Preamplifier does not feature a built-in amplifier and requires a separate high quality external power amplifier(s), such as the Marantz MM8077, MM7055 and MM702 (all sold separately - see Accessories Tab).

    11.2-Channel Assignment: The Marantz AV7705 preamplifier supports up to 11.2 channel or 7.2.4 channel playback and can be configured in a variety of ways to accommodate your system's setup.

    • 11.2ch: This configuration can be used for a Dolby Atmos home theater system with a 7.2.4 speaker setup; using either overhead, height or Dolby Atmos enabled speakers.
    • 9.2ch: This configuration can be used for a Dolby Atmos home theater system with a 5.2.4 or 7.2.2 speaker setup; using either overhead, height or Dolby Atmos enabled speakers.
    • 9.2ch (Bi-Amp): This configuration can be used for a 5.2.4 or 7.1.2 Dolby Atmos system, while Bi-amping the front speakers.
    • 9.2ch (Front B): This configuration can be used for a 5.2.4 or 7.1.2 Dolby Atmos system, while powering a secondary pair of front speakers.

    Current Feedback Topology: The Marantz AV7705 uses a high-speed current feedback amplifier circuit for its preamplifier so that audio signals from a Blu-ray Disc player and other equipment that support high-definition audio formats can be listened to with high fidelity. Current Feedback technology offers faster signal handling and extended frequency range. Current feedback circuits track rapid sonic changes more accurately and thus sound more natural. Current feedback topology insures astounding accuracy and control even under high-drive conditions.

    HDAMs (Hyper-Dynamic Amplifier Modules): The AV7705 utilizes Marantz's proprietary HDAM (Hyper-Dynamic Amplifier Module) circuits for dynamic music and soundtrack reproduction. HDAMs combine the short signal path advantages of ICs (integrated circuit) and op-amps (operational amplifier) with the superior sound quality of separate circuit components. Because HDAMs are discrete designs, Marantz engineers are free to choose the parts best able to preserve the sonic details of your favorite sources.

    Optimized Components: The carefully-optimized audio/video signal paths rest on separate circuit boards for maximum performance as well as isolation from interferences generated by high-speed video processing.  In addition, Marantz surround preamplifier employs a high current linear power supply with an EI core power transformer for high-quality sound playback.

    Advanced 32-Bit D/A Conversion On All Channels: For optimum fidelity and the widest dynamic range with lowest distortion, the AV7705 features advanced reference-class 32-bit AKM D/A converters on all channels. This ensures consistent high fidelity and precise channel matching across all channels for the ultimate listening experience. In addition, the preamplifier utilizes a Hybrid PLL Clock Jitter Reducer to eliminate distortion caused by jitter errors for a more accurate reproduction of the recording the way the artist intended.

    • Dolby Atmos: Dolby Atmos surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the soundtrack designer the ability to precisely place sounds anywhere in the 3-dimensional space. Now you can enjoy this same award-winning technology at home with the AV7705 that lets you to connect a 5.1 or 7.1 surround sound speaker system and 2-4 additional overhead speakers or 2-4 Dolby Atmos elevation speakers for the ultimate home theater experience.
      • A 5.1.2 configuration is based on a traditional 5.1 speaker layout complemented by 2 overhead or Dolby Atmos-enabled speakers.
      • A 5.1.4 configuration is based on a  traditional 5.1 speaker layout complemented by 4 overhead or Dolby Atmos-enabled speakers.
      • A 7.1.2 configuration is based on a more advanced 7.1 speaker layout complemented by 2 overhead or Dolby Atmos-enabled speakers.
      • A 7.1.4 configuration is based on a more advanced 7.1 speaker layout complemented by 4 overhead, or Dolby Atmos-enabled speakers.
    • DTS:X: The latest immersive surround sound system, DTS:X features object-based audio coding that lets the soundtrack designer place sonic elements anywhere in the 3D acoustic soundspace, and provides for overhead speakers to deliver a stunning surround sound experience. Along with DTS:X decoding, the AV7705 features DTS-HD Master Audio decoding and other DTS audio technologies.
    • AURO-3D: This preamplifier is equipped with an Auro-3D decoder. With Auro-3D, Front Height, Surround Height and Top Surround are added to a conventional 5.1-channel system to achieve a natural and realistic soundfield that is three-dimensional and fully immersive. You will be able to fully enjoy Auro-3D playback if you properly place the speakers for Auro-3D. Auro-3D does not support a Dolby Atmos configuration using Top Front, Top Middle, Top Rear, or any Dolby Atmos Enabled speakers. But it is possible to support both an Auro-3D and Dolby Atmos by adding Front Height and Rear Height speakers to a 5.1 configuration. For an optimum Auro-3D experience Surround Height speakers are strongly recommended.

    Post Decoding Formats: The Marantz AV preamplifier supports Dolby Surround & DTS Neural:X to enhance 2-channel and multichannel decoding formats. It will also be able to support DTS Virtual:X through a future firmware update (no ETA).

    • Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch, 7.1ch, or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
    • DTS Neural:X: Further, DTS:X incorporates Neural:X, the latest spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
    • DTS Virtual:X (via Future Firmware Update): DTS Virtual:X bridges the gap between DTS:X and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. DTS Virtual:X can be used with any content (from 2ch to 5.1ch soundtracks), while delivering virtual height & virtual surround processing based on psychoacoustics (not reflective surfaces).

    IMAX Enhanced Technology (Firmware Update Scheduled for January 2019): Get the most premium at-home entertainment experience with IMAX Enhanced; the latest technology program from IMAX that sets a new standard for image, sound, scale and content quality.

    Audyssey  Suite: The Marantz AV7705 features the Audyssey suite of powerful DSP features - including MultEQ XT32, Sub EQ HT, LFC (Low Frequency Containment), Dynamic Volume, and Dynamic EQ.

    • MultEQ XT32: Via the supplied measuring microphone, Audyssey MultEQ32 measures all the speakers in your home theater during setup, including the subwoofer, and then generates multiple high precision DSP room acoustic correction filters, which together provide smoothest and most natural tonal balance, regardless of the brand or model of the various speakers. Audyssey MultEQ32 incorporates Up to eight listening positions can be measured, configured, and recorded. MultEQ XT32 compensates for both time and frequency characteristics of the listening area based on "Audyssey Setup" measurement results. Selection is done from three types of compensation curves - Reference (default and recommended, L/R Bypass, Flat, and Off).
    • Sub EQ HT: Audyssey Sub EQ HT provides individual DSP tailoring of each subwoofer in a dual subwoofer setup, for deeper bass with improved definition, compared to a single subwoofer configuration.
    • LFC (Low Frequency Containment): Audyssey Low Frequency Containment uses advanced psychoacoustic algorithms to deliver a full range tonal balance, including deep bass, but without disturbing close-by neighbors or family members in other rooms, and features a multi-step adjustment that lets you dial in the amount of containment to your preference.
    • Dynamic Volume: Audyssey Dynamic Volume features advanced psycho-acoustic processing to deliver clear dialog and wide range sound at reduced volume levels so that you can enjoy theater-level clarity at whatever listening level you choose.
    • Dynamic EQ: Audyssey Dynamic EQ also features advanced DSP processing to deliver full range wide-band response, even at reduced volume levels. Dynamic EQ Reference Level Offset provides three offsets from the film level reference (5 dB, 10 dB, and 15 dB) that can be selected when the mix level of the content is not within the standard.

    Listening Modes: The Marantz AV7705 features a variety of Listening modes to choose from, so you can enjoy your movie or music soundtrack the want you to hear it.

    • Auto Detection: In Auto Mode, the Listening Mode switches automatically to the corresponding type of audio input signal (Dolby Digital, Dolby TrueHD, Dolby Digital Plus, DTS, DTS-HD, or multichannel PCM) that is detected. If the input signal is analog or PCM (2-channel), stereo playback is used.
    • Direct Listening Modes: The Marantz AV7705 offers two Direct Listening Modes which bypass the preamplifier's tone & DSP processing for higher sound quality performance. Source Direct provides playback of 2ch or Multichannel audio in its original form, without any surround or tone processing. Pure Direct  goes a step further by turning off the preamplifier's display and analog video circuitry to minimize the possibility of any noised being added to the audio signal.
    • Stereo Modes: The Marantz AV7705 surround preamplifier also provides two-channel stereo and multi-channel stereo playback, as well a virtual surround from two stereo speakers. The 2CH Stereo mode is for playing in two channel stereo; bass and treble can be adjusted and sound is output from the front left and right speakers, along with a connected subwoofer. Multi-Channel Stereo mode lets you enjoy stereo sound from all speakers. Virtual Speaker mode lets you enjoy surround effects using only the front speakers or headphones.

    Audio Enhancements: The Marantz AV7705 preamplifier provides various audio enhancements to deliver a high-quality listening experience every time.

    • CINEMA EQ (Cinema Equalizer): The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Digital, DTS, Dolby Pro Logic (including PL II, PL IIx, PL IIz), and DTS Neo:6 modes.
    • M-DAX: Compressed audio formats such as MP3, WMA (Windows Media Audio) and MPEG-4 AAC reduce the amount of data by eliminating signal components that are hard for the human ear to hear. The M-DAX function generates the signals eliminated upon compression, restoring the sound to conditions near those of the original sound before compression. It also corrects the sense of volume of the bass to obtain richer sound with compressed audio signals.
    • Dynamic Range Compression (DRC): Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, Compressing the dynamic range allows you to hear all of the sounds in the soundtrack with reduced dynamic range. DRC works when playing program sources recorded in Dolby Digital or DTS.
    • Center Spread: When using the preamplifier's Dolby Surround mode, the Center Spread function expands the center channel signal to left and right front speakers to create a wider frontal audio image for the listener. It is optimized and designed primary for playback of stereo music content.

    ARC + eARC (via available Firmware Update): ARC (Audio Return Channel) allows the receiver's HDMI monitor output allows audio to be sent from your compatible HDTV to the preamplifier through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television. The preamplifier will also support eARC (Enhanced Audio Return Channel) via an available firmware update. eARC will support uncomprerssed audio formats like Dolby TrueHD, Dolby Atmos, DTS:X, & DTS HD Master Audio - where standard ARC was limited to Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

    Volume & Level Settings: The Marantz AV7705 offers the following volume & level settings.

    • Volume Settings: You can choose to display an Absolute volume scale (0-98) or Relative volume scale (-79.5 to 18dB). You can also set a maximum volume level of 0 (80), -10 (70), or -20 (60) dB to limit the preamplifier's total volume output. In addition, you can define the volume setting that is active when the power is turned on; select "Mute", -79 to +18dB (1-98), or Last.
    • Mute Level: You can set the amount of attenuation for the audio muting circuit; -40dB or -20dB below current volume, or full mute (sound turned off entirely). Volume settings can be adjusted independently for the Main Zone and Zone 2.
    • Channel, Center, & Subwoofer Level: The volume level (-12 to +12dB) of each channel can be changed while listening to audio for each input source. You can also adjust the center channel volume level (-12 to +12dB) independently from the channel level to clarify the dialog for all sources. In addition, you can adjust the subwoofer channel volume level (-12 to +12dB) independently from the channel level to emphasize low frequencies for all input sources.
    • Source Level: This function adjusts the playback level of the currently selected input source's audio input. Use this feature if there are differences in the input volume levels between different sources. You can correct the playback level of the audio input from -12 to +12dB.

    7.1 Channel Input: The AV7705 features a 7.1 Channel input (Front left, Front right, Center, Surround left, Surround right, Surround Back left, Surround Back right and Subwoofer) for connecting a DVD Audio player, Super Audio CD multi-channel player, or other component that has a multi-channel port so you can playback the audio with 5.1 channel or 7.1 channel surround sound.

    Phono Input: The AV7705's phono input (MM) lets you connect to a turntable and offers the amplification that this weaker signal requires. The preamp's phono circuitry prepares the signal from the turntable for amplification, letting you enjoy your vinyl collection at full volume without tonal distortion. The HDAM component of the Marantz AV7705 outperforms op-amp solutions due to its high speed and maintains a clean audio signal for exceptional sound performance.

    Headphone Output: The AV surround preamplifier features a 1/4" stereo headphone jack on its front panel for connecting a pair of optional headphones. The unit's speakers will automatically be turned off when a set of headphones are connected.

    Video Features

    HDMI 2.0b: Featuring eight HDMI inputs (7 rear/1 front) and three HDMI outputs, the AV7705 incorporates an advanced video section that features the latest HDMI 2.0b specification, including support for 4K/60 Hz Ultra-HD video, BT.2020 Wide Color Gamut, High Dynamic Range (HDR), & 4:4:4 Pure Color sub-sampling and 21:9 video pass-through, along with support for 3D content. The AV7705 also features HDCP 2.2 compatibility, a requirement for 4K Ultra HD copy-protected content.

    • 4K/60Hz + HDCP 2.2: The AV7705's HDMI inputs and monitor output support up to 4K (3840x2160 pixels) video @ 60 frames per second. All of the HDMI jacks support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission. The preamplifier will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI.
    • 4:4:4 Color Subsampling: The HDMI inputs and monitor output support RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail. The front-panel HDMI only supports 4K 60/50Hz using format YCbCr 4:2:0 only.
    • Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
    • 21:9 Aspect Ratio: By supporting 21:9 aspect ratio, this preamplifier can show films recorded in the Cinema Scope format on your TV for a much more immersive video experience. When these types of films are viewed in the usual 16:9 ratio, you see black bars at the top and bottom of the screen; 21:9 eliminates these bars.
    Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.

    HDR Compatibility: HDR provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. The preamplifier supports HDR 10, Dolby Vision, and HLG.

    • HDR 10: HDR 10 is an open standard and currently the most popular HDR format on the market. It supports 10-bit color and 1,000 nits. It uses static metadata at the start of a movie to tell the preamplifier and your TV that the video content is encoded using HDR.
    • HLG: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
    • Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision utilizes dynamic metadata which adjusts brightness, color, and contrast automatically for each scene. Dynamic metadata carries information that maps every image to your TV's display capabilities, so you see more of what the content creator intended. Dolby Vision supports 12-bit color and 10,000 nits.

    4K Video Upconversion & Upscaling: The Marantz AV preamplifier's sophisticated video processor  provides upconversion from standard definition (480i/480p) and high definition (720p/1080i/1080p) sources to 4K Ultra HD (3840x2160 pixels), which lets you connect all your analog (composite/component) or digital (HDMI) video sources to the AV7705 and then connect to your TV with just a single HDMI cable. Only the preamplifier's main HDMI output supports video upconversion.

    Note: When composite or component video signals are used, only 480i video signals are converted to HDMI (up to 4K).

This display shows menu choices for custom setup and other data to help you get the most out of your new AV surround preamplifier.

    On-Screen Menu w/ Setup Wizard (via HDMI): With the on-screen graphical display that combines large clear text and colorful icons, plus the Marantz Setup Assistant, setup is both simple and quick, letting you easily make all necessary adjustments and settings to quickly and easily optimize the AV7705 for your particular speaker configuration and source equipment. When you control the sound volume, the volume level is displayed on the screen, and when you switch the input source, the name of the input source is displayed. The on-screen menu display can only be output to your TV via HDMI.

    Notes:

    • The on-screen menu and setup assistant is required for initial setup and is only available through the receiver's HDMI output.
    • The on-screen menu is only supported by the main HDMI monitor output.
    • The video being played will not appear in the background of the menu when the menu is operated during playback of 4K, HDR, or 3D video; or if the video aspect ratio is not 16:9 or 4:3.

    Smart Select: On the front-panel, you'll find four Smart Select buttons that let you quickly choose from the most popular input sources; the ergonomically designed remote also includes Smart Select function buttons. With Smart Select, the AV preamplifier remembers not only your preferred inputs but also your preferred audio settings, so you can enjoy precisely tailored sound with each one.

    Gapless Playback: Many live and classical albums have no gaps in the music. Gapless playback ensures that there are no pauses between audio files. This provides playback with no interruptions, the way it was meant to be heard. Compatible with FLAC, WAV, AIFF, ALAC, and DSD music files via USB or DLNA.

    Input Name & Delete: You can change the display name (up to 12 characters) of a selected input source. If an input isn't being used, you can delete it from the display so you don't have to scroll past it when you change sources.

    Lock Functions: To prevent accidental operation of the AV preamplifier, you can disable operation of the buttons on the front-panel. You can also disable the preamplifier's IR sensor to prevent accidental operation of the preamplifier from the remote control. You can even disable operation of only Zone 2 or Zone 3 from the remote control. 

    Timers: The Marantz AV preamplifier features a programmable Sleep Timer and Auto Standby function.

    • Sleep Timer: This function allows you to automatically set the power to standby after a predetermined amount of time has passed; set the sleep timer up to 120 minutes in 10 minute increments.
    • Auto Standby: The unit enters standby mode automatically when no commands are sent to the unit for the set time (15/30/60 minutes). Before it enters the standby mode, "Auto Standby" is displayed on the front-panel display of this unit and the on-screen menu.

    Personal Memory Plus: For each input, the AV preamplifier automatically memorizes the settings for input mode, surround mode, HDMI output mode, audio delay, etc. When the input source is switched, the settings last used for that source are automatically recalled. The surround parameters, tone control settings, and playback levels for the different output channels are memorized for each surround mode.
