Preamp/Processor Advantage: Delegating the amplification duties to a separate component allows the Marantz AV7703 AV 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. The AV7703 features both balanced (XLR) and unbalanced (RCA) preamp outputs.
- 11.2Ch Balanced XLR Preouts: If your power amplifier is equipped with balanced XLR inputs, then use the AV7703's balanced XLR preouts. The AV7703's 11.2ch balanced XLR preouts 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. Balanced connections guard against induced noise and allow long cable runs without compromising sound quality. If you are connecting the AV7703 to a "vintage" 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 Preouts: If your power amplifier is not equipped with balanced XLR inputs and only offer unbalanced RCA inputs, then use the AV7703's unbalanced RCA preouts. The AV7703's 11.2ch unbalanced RCA preouts 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.
Note: The Marantz AV7703 AV Surround Preamplifier does not feature a built-in amplifier and requires a separate power amplifier, such as the Marantz MM8077 seven-channel power amplifier (642MM8077, sold separately).
11-Channel Assignment: The Marantz AV7703 AV preamplifier supports up to 11.1 channel playback and can be configured in a variety of ways to accommodate your system's setup.

Current Feedback Topology: The Marantz AV7703 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 AV7703 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. The Marantz AV7703 is also equipped with a Hybrid PLL Jitter Reducer that is capable of reducing jitter and phase noise that negatively affect sound quality. The Hybrid PLL Jitter Reducer improves the sound localization, reproducing a natural sound field. In addition, Marantz surround preamplifier employs a high current linear power supply with an EI core power transformer for high-quality sound playback.
32-Bit/192kHz DACs: The Marantz AV7703 utilizes a 192kHz/32-bit D/A converter on each of the unit's seven channels for exceptional, audiophile-grade sound quality. The 192kHz sampling and 32-bit word length capabilities of the DACs allows you to play high-resolution recordings and hear the increased clarity, detail and dynamic range of those recordings.

- 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 AV7703 features DTS-HD Master Audio decoding and other DTS audio technologies. DTS:X will require a firmware update.
Post Decoding Formats: The Marantz AV surround preamplifier supports Dolby Surround, DTS Neural:X, and DTS Neo:6 (Music/Cinema) to enhance 2-channel and multichannel decoding formats.
- Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch and 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: 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 Neural:X will require a firmware update.
- DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that takes any two-channel source (including television broadcasts, CDs and DVDs) and expands it into five or six channels. It also provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 brings you a more revealing sound from ordinary stereo and a more expansive home cinema experience.
AURO-3D Upgrade ($199): Auro-3D is the next generation three-dimensional audio standard. It provides a realistic sound experience unlike anything before. By fully immersing the listener in a cocoon of life-like sound, Auro-3D creates the sensation of actually "being there". Thanks to a unique "Height" channel configuration, recorded acoustic reflections are reproduced by these speakers and are heard naturally due to the fact that sounds originate from around as well as above the listener. Once upgraded with the AURO-Codec Decoder, the AV7703 is capable of decoding the original Auro-3D mix and playing back an Auro 9.1 or 10.1 channel configuration.
Audyssey Platinum: The AV7703 features the Audyssey Platinum suite of powerful DSP features; including MultEQ XT32, Sub EQ HT, LFC, 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 LFC solves the problem of low frequency sounds disturbing people in neighboring rooms or apartments. Audyssey LFC dynamically monitors the audio content and removes the low frequencies that pass through walls, floors and ceilings. It then applies psychoacoustic processing to restore the perception of low bass for listeners in the room. The result is great sound that no longer disturbs the neighbors.
- 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.
Direct Listening Modes: The Marantz AV7703 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 AV7703 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 AV7703 surround 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.
- Dialog Control: When listening to a DTS:X soundtrack, the Dialog Control feature adjusts the volume of dialog in movies and vocals in music, so voice can be heard more easily.
Level Adjustments: The AV7703 provides the following level adjustments.
- 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.
- Dialogue Level: You can adjust the output level (+/-12dB) to clarify the dialogue output from the center channel.
- EQ Level: If you choose not to use the Audyssey MultEQ X32 auto calibration setup function, you can manually set the tonal balance and level for each frequency band of the preamplifier's 9-band EQ (63/125/250/500/1k/2k/4k/8k/16k Hz) for each connected loudspeaker.
- Subwoofer Level: You can set the preamplifier's subwoofer output level (+/-12dB) independent from the other speaker levels and system's main volume.
Volume Settings: The AV7703 offers the following volume settings.
- Volume Scale: You can choose to display an Absolute volume scale (0-98) or Relative volume scale (-79.5 to 18dB).
- Volume Limit: You can set a maximum volume level of 0dB (80), -10dB (70), or -20dB (60) to limit the preamplifier's total volume output.
- Turn-On Volume: You can define the volume setting that is active when the power is turned on (0, 1-98, -79 to +18dB, 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).
7.1 Channel Input: The AV7703 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 AV7703's phono input 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.
Dual Discrete Sub Outputs: For compatibility with dual subwoofer home theater systems, the AV7703 features two discrete subwoofer outputs. With a single subwoofer, room acoustics and the subwoofer's location in the room may not deliver optimum deep bass response. Instead, because of room resonances, deep bass quality may be uneven due to room interaction. With dual subwoofer outputs you can connect two subs and place them in different parts of the room, and enjoy smoother and more accurate deep bass response as a result.
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.
HDMI 2.0a: Featuring eight HDMI inputs (including one conveniently located on the front-panel) and three HDMI outputs, the AV7703 incorporates an advanced video section that features the latest HDMI 2.0a 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.

- HDCP 2.2: All of the preamplifier's HDMI jacks support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
- 4:4:4 Color Subsampling: All of the preamplifier's rear-panel HDMI jacks 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.
- HDR (High Dynamic Range): 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.
- 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.
Three HDMI Outputs: The two parallel HDMI outputs distribute the same video signal simultaneously to two separate displays, while the discrete HDMI output allows you to play a different audio/video source in another zone.
4K Video Upconversion: 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 AV7703 and then connect to your HDTV with just a single HDMI cable. Only the preamplifier's main HDMI output supports video upconversion.
Other HDMI Features: The Marantz AV7703 AV preamplifier's HDMI connectivity also offers 3D video pass-through, ARC (Audio Return Channel), Deep Color & x.v.Color support, as well as an auto LipSync function.

- ARC (Audio Return Channel): This feature of the AV7703's main HDMI monitor output allows audio to be sent from your compatible HDTV to the AV surround preamp 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.
- Deep Color & x.v.Color Support: The AV surround preamplifier supports Deep Color and x.v.Color content, which can display a larger color range than standard-definition schemes. The result is a more lifelike, vibrant picture
- LipSync: This function adjusts the delay between audio and video output. You can do this manually or have the AV surround preamp set the LipSync function automatically. When connected to a TV via HDMI the AV surround preamp automatically adjusts audio output timing (0-500ms) if the TV supports an automatic LipSync function. You can also manually delay the sound output up to 500ms to synchronize it with the video image.
HDMI Standby Pass-Through: When the AV surround preamplifier is in "Standby" mode and the HDMI Standby Pass-Through function is enabled, both audio/video streams from the AV surround preamps HDMI input will be output to your television, via the AV preamplifier's HDMI monitor output. Once the AV surround preamp is turned "On", only video will pass through the monitor output to your TV and the audio is directed to the preamplifier's speaker outputs.
