Preamp/Processor Advantage: Delegating the amplification duties to a separate component allows the Marantz AV7702 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.
Note: The Marantz AV7702 AV Surround Preamplifier does not feature a built-in amplifier and requires a separate power amplifier, such as the Marantz MM7055 five-channel power amplifier (642MM7055, sold separately).
Current Feedback Topology: The Marantz AV7702 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 AV7702 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 AV7702 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.
24-Bit, 192 kHz D/A Converters: The AV7702 uses 24-bit/192-kHz Digital-to-Analog converters for all channels. The 192kHz sampling and 24-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.
Digital Signal Processing (DSP): The Marantz AV7702 is equipped with a high-resolution SHARC 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. The AV7702 is equipped with various surround modes to reproduce a variety of surround sound effects, according to the content of the source to be played. The AV surround preamplifier features Dolby Digital and DTS-HD decoding, as well as offers Dolby Pro Logic audio processing.
Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the A/V preamplifier via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the preamp must be connected to your Blu-ray player via HDMI.
- Dolby Digital: Dolby Digital, Dolby Digital Plus, Dolby TrueHD
- DTS: DTS, DTS-ES, DTS-HD Master Audio, DTS-HD High Resolution, DTS Express, DTS 96/24, DTS Neo: 6, DTS Neo:X (11.1ch)
- Dolby Pro Logic: Dolby Pro Logic II, Dolby Pro Logic IIx
Dolby Atmos: In addition to Dolby TrueHD and DTS-HD Master audio high-resolution lossless decoding, the AV7702 is one of the first to incorporate Dolby Atmos advanced surround decoding. Dolby Atmos is an object-based surround sound encoding and decoding system, and is found in many of the world's premier movie theaters. With Dolby Atmos, sounds can be placed with pinpoint precision anywhere in the listening space, via the use of ceiling speakers or Dolby Atmos-compatible main speakers, and the system is truly scalable to match the surround decoding specifically to any particular listening space and speaker complement up to a 7.2.4 speaker configuration.
- Ceiling Mounted Speakers: Ceiling speakers are used for maximizing effects in Dolby Atmos listening mode. Install these speakers midway between the position just above the listening position and the position just above the front speakers, or simply install them just above the listening position.
- Dolby Enabled Speakers: There are two types of Dolby Enabled Speakers; one is to be placed on the top board of other speakers such as front speakers and surround speakers; the other is integrated within the front or surround speakers. Dolby Enabled Speakers are designed with their output facing toward the ceiling to create an elevated audio effect in the Dolby Atmos mode by providing sounds echoing off the ceiling.
Note: Globally, more than 100 cinema blockbusters have been released featuring Dolby Atmos soundtracks in the past two years, and many more are on the way. Major Hollywood studios are partnering with Dolby to create home video versions of current box office releases and previously released favorites for release in 2014 and 2015.
Dolby Surround: Dolby Surround offers an enhanced cinema experience to your Dolby Digital (Plus/TrueHD) and DTS (ES/HD) movie soundtracks using your existing 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".
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 AV7702 is capable of decoding the original Auro-3D mix and playing back an Auro 10.1 channel configuration.
11-Channel Assignment: The Marantz AV7702 AV preamplifier supports up to 11.2 channel playback and can be configured in a variety of ways to accommodate your system's setup.
- 5.2ch: This serves as a basic 5.2-channel surround system with Front, Center, and Surround speakers, plus dual subs.
- 7.2ch (Surround Back): This serves as a basic 7.2-channel surround system with Front, Center, Surround, and Surround Back speakers, plus dual subs.
- 9.2ch (Front Height): Plays back up to 9.2-channels at the same time; including Front, Center, Surround, Surround Back, and Front Height speakers, plus dual subs.
- 9.2ch (Front Wide): Plays back up to 9.2-channels at the same time; including Front, Center, Surround, Surround Back, and Front Wide speakers, plus dual subs.
- 9.2ch (Bi-Amp): This system will consist of 9 speakers with the Front speakers bi-amped, plus dual subs. This speaker configuration will include Front, Center, Surround, Surround Back, and either Front Height or Front Wide speakers.
- 9.2ch (Front B): This system will consist of 9 speakers with the two pair of front speakers (A & B), plus dual subs. This speaker configuration will include Front A, Front B, Center, Surround, and Surround Back or Front Wide/Front Height speakers.
- 11.2ch: This mode lets you connect up to 13.2 channels and will automatically switch between output channels according to the input signal and soundfield. You can connect Front, Center, Surround, Surround Back, Front Height 1, Front Height 2, and Front Wide speakers, plus dual subs.
- Dolby Atmos: This speaker configuration is optimized for Dolby Atmos playback. You can configure a 5.2.2ch, 5.2.4ch, 7.2.2ch, or 7.2.4ch Dolby Atmos speaker system.
Direct Listening Modes: The Marantz AV7702 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 AV7702 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.
Audyssey Platinum: The AV7702 features the Audyssey Platinum suite of powerful DSP features; including MultEQ XT32, Dynamic Volume, Dynamic EQ, and Audyssey DSX.
- MultEQ XT32: Via the supplied measuring microphone, Audyssey MultEQ XT32 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. MultEQ XT32 provides greater filter precision for the main and surround speakers, with 8x the resolution compared to the base MultEQ system, along with the ability to measure at up to 32 locations in the room. 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).
- Audyssey Sub EQ HT + LFC: Audyssey Sub EQ HT provides individual tailoring for each subwoofer in a dual subwoofer setup, delivering the optimum combination of highest deep bass output and lowest distortion. Audyssey LFC processing analyses and processes bass content on a continuous basis and custom tailors the sound via advanced psychoacoustic algorithms to deliver dynamic bass response within the listening room without annoying family members or neighbors in adjacent rooms.
- 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.
- Audyssey Dynamic Surround Expansion (DSX): Audyssey DSX adds front effect speakers to improve spatial sound reproduction. Starting with a 5.1 channel system, DSX adds front Wide and/or front Height channels for better sound staging (although both wide and height speakers can be added, only one pair is used at a time). DSX also applies Surround Envelopment Processing to enhance the blend between the front and surround channels.
Surround Parameters: You can adjust the following surround mode parameters.
- Dolby Pro Logic II Music Settings: While listening in the Dolby Pro Logic II Music format, there are three further enhancements you can adjust - Panorama (broadens the front stereo image to the surround speakers to provide a wraparound effect, especially effective when there is limited output from the surround channels), Dimension (allows you to move the sound field forward or backward), and Center Width (allows you to adjust the width of the center channel).
- Center Image: In the Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).
- Audyssey DSX Settings: While listening in the Audyssey DSX audio format, there are two further enhancements you can adjust; Stage Height (adjust sound stage height +/-10 when using front height speakers) and Stage Width (adjust sound stage width when using front wide speakers)
- Height & Center Gain: Adjust the volume (Low/Mid/High) of the Front Height channels in Dolby Pro Logic IIz. During DTS NEO:X, this function distributes the dialog output from the center channel to the front left and right channels and widens the sound image in t he front.
Audio Enhancements: The Marantz AV7702 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.
Level Adjustments: The AV7702 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.
- Subwoofer Level: You can set the preamp's subwoofer output level (+/-12dB) independent from the other speaker levels and system's main volume.
Volume Settings: The AV7702 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).
Audio Inputs/Outputs: The Marantz AV preamplifier/processor offers a variety of analog and digital audio inputs/outputs.
- Balanced/Unbalanced Preamp Outputs: The AV7702 features both unbalanced RCA (13.2ch) and balanced XLR (11.2ch) preamp outputs. Preamp outputs include Front L/R, Center, Surround L/R, Surround Back L/R, Front Height 1 L/R, Front Height 2 L/R, Front Wide L/R, and Dual Subs) for connection to external power amplifiers. For compatibility with dual subwoofer home theater systems, the AV7702 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.
- Note: If you are connecting the AV7702 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).
- Assignable Digital Inputs: There are two coaxial digital inputs and two optical digital inputs. The inputs accept digital audio signals from a compact disc, DVD, Blu-ray, or other digital source component. There is also 1 optical digital output. Each input can be assigned to any of the different input sources except Tuner.
- 7.1 Channel Input: The AV7702 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. If you will not be using the 7.1 channel input with a multi-channel decoder, you can use the front and left inputs as an auxiliary input.
- Phono Input: The AV7702'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.
- 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.
