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.

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.

Advanced 32-Bit D/A Conversion On All Channels: For optimum fidelity and the widest dynamic range with lowest distortion, the AV7703 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 AV 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.

Digital Signal Processing (DSP): The Marantz AV7703 is equipped with a high-resolution 32-bit Digital Signal Processor (DSP). All elements of the Surround Processor are optimized to the highest standards by the use of selected high performance and discrete components, particularly the A/D and D/A converters and the sophisticated DSP surround decoder.

Compatible Digital Audio Formats: The Marantz AV7703 supports the following stereo & multichannel digital audio formats through its HDMI jacks and optical/coax digital inputs.

Immersive Surround Sound: The Marantz AV7703 AV surround preamplifier goes beyond regular surround with the latest immersive surround sound formats, including Dolby Atmos & DTS:X.

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.

Apple Device Compatibility Chart: The Marantz AV7703 is "made for iPod/iPhone" and supports the following iPod/iPhone model function (as of 10/24/2016).

Multiroom Playback

HDMI Zone 2: The AV7703 incorporates multi-zone HDMI audio/video distribution for Zone 2 with the inclusion of its HDMI matrix switching functionality. The AV surround preamp can send two different HDMI video feeds to two displays at the same time directly from the AV surround preamp (HDMI Zone 2 does not support upscaling). HDMI Zone 2 also supports 2ch PCM audio from the HDMI input source selected. The HDMI Zone 2 function is only compatible with the HDMI 1-7 input connectors. It is not compatible with the HDMI 8 input connector. The volume of HDMI Zone 2 will be controlled by your TV or additional AV surround preamp in Zone 2.

• Compatible Sources: Compatible HDMI Zone 2 sources include the preamplifier's HDMI 1-7 inputs.
• Incompatible Sources: The preamplifier's HDMI 8 input cannot be output to Zone 2. Analog audio/video signals cannot be sent to HDMI Zone 2. USB, Bluetooth, iPod/iPhone, AirPlay, Internet Radio, HEOS music apps, and DLNA sources cannot be output to HDMI Zone 2.

Audio/Video Zone 2: Zone 2 allows stereo audio/video playback of another A/V source connected to the AV surround preamp in another room of your home via stereo pre-out connections, as well as composite or component video. To enjoy a video source in Zone 2, you must connect the same video connection to your second display monitor as connected to your AV surround preamp for that particular source (there is no video-conversion for Zone 2). Zone 2 features stereo pre-outs, so you can use a separate amp to power speakers in another room. When using the preamplifier's pre-outs for the second room you'll need an amplifier in that room to power those speakers. The volume of Zone 2 can be controlled by the Marantz preamplifier or from your add-on integrated amplifier.

• Compatible Sources: Compatible Zone 2 sources include Analog audio/video inputs, HDMI audio (2ch PCM), Optical/Coaxial digital inputs (2ch PCM), AM/FM Tuner (cannot select different stations for each zone), USB (including iPod/iPhone), AirPlay, Bluetooth, Internet Radio (different network sources cannot be played back in multiple zones at the same time), HEOS music apps, DLNA/Media Server contents.
• Incompatible Sources: DSD audio cannot be sent to Zone 2. Unfortunately, you cannot select USB and Network sources exclusively for each Zone. For example, if you select a network source for Zone 2 when a USB source is selected for the Main Zone, the input source in the Main Zone also switches to the same network source as Zone 2 (this scenario also includes Bluetooth).

Audio Only Zone 3: Zone 3 allows you to play a different stereo audio source connected to the preamplifier in a third room of your house. When using the preamplifier's Zone 3 preamp output terminals for a 3rd Zone, you need an additional amplifier in that room to power those speakers. The volume of Zone 3 can be controlled by the Marantz preamplifier or from your add-on integrated amplifier.

• Compatible Sources: Analog audio inputs, Optical/Coaxial digital inputs (2ch PCM), AM/FM Tuner (cannot select different stations for each zone), USB (including iPod/iPhone), AirPlay, Bluetooth, Internet Radio (different network sources cannot be played back in multiple zones at the same time), HEOS music apps, DLNA/Media Server contents.
• Incompatible Sources: Analog video, HDMI audio/video, and DSD audio cannot be sent to Zone 3. Unfortunately, you cannot select USB and Network sources exclusively for each Zone. For example, if you select a network source for Zone 3 when a USB source is selected for the Main Zone, the input source in the Main Zone also switches to the same network source as Zone 3 (this scenario also includes Bluetooth).

All Zone Stereo Function: The All Zone Stereo function allows you to enjoy the AV preamplifier's Main Zone audio source in Zone 2 simultaneously (regardless of input audio signal types; analog or digital). During the All Zone Stereo mode, only the "Multi Ch Stereo" and "Stereo" sound modes can be selected. You will have independent volume control in each zone. All Zone Stereo mode is useful when you want to enjoy the same music at the same time in multiple rooms during a get together or party.

HEOS Wireless Multiroom: Built-in HEOS technology allows the AV7703 to become part of the HEOS wireless multiroom system, allowing you to enjoy your favorite music throughout your home. Share music stored on your home network, Internet radio & online streaming services, plus the music library on your smartphone or source components connected to the AV surround preamp with multiple HEOS wireless speakers and other HEOS components throughout your house. And it's all controlled by the free HEOS app, installed on your Apple iOS (7.0+) or Android OS (2.3+) device. The app gives you instant multiroom audio control, meaning you can command music in every room from any device - play different music from different sources in every room, group several rooms together and play the same song.

• Music: You can select which sources you want to listen to from the app. Choose from the preamplifier's connected sources (2ch PCM only), a variety of online music services and internet radio, plus the music library on your computer (DLNA) or iPhone/Android device, and even Bluetooth.
