Mô tả sản phẩm: Marantz AV7702 AV Preamp/Processor
The AV7702 is extremely versatile. Not only does it perfectly and expertly handle any kind of high resolution multichannel audio format but it also offers an extended network package including audio streaming, internet radio, Spotify Connect and AirPlay. It even includes built-in WiFi and Bluetooth capabilities. But please note: to get the best of the latest high-resolution DSD and FLAC HD format, we recommend hard-wiring the units. Superb surround sound audio quality from the latest tone formats is guaranteed by the powerful 32-Bit SHARC DSP offering high channel separation that leaves no chance for any crosstalk. Tone formats include Audyssey DSX, DTS Neo:X 11.1 and the latest decoding technology Dolby Atmos – which not only provides breath-taking surround sound but also opens the door to 3D sound. In addition, the 11.2 channel AV7702 further enhances audio quality by delicately handling all signals via the Marantz-own current feedback HDAMs preamp, before passing them to the high-quality 11.2 XLR or 13.2 RCA outputs and separate power amp. The AV7702 also takes supreme care of video signals via the eight HDMI 4k 60Hz pass through / scaling inputs and sends them to the two HDMI output sockets or independently to the third HDMI output that is dedicated for Multiroom. There is even a Phono MM input – ideal for those precious vinyls. Set-up and operation is quick and easy via the Audyssey MultEQ XT32 auto-calibration and high-resolution Graphic User Interface. It’s all there, just waiting to perform.
8 HDMI Inputs, 3 HDMI Outputs with 4K Ultra HD 60 Hz Pass-through; 4:4:4 Pure Color
Equipped with an advanced video processor section, the AV7702 features 8 HDMI inputs, including 1 conveniently located on the front panel, and feature 4K Ultra HD 60 Hz full rate pass-through for the next generation of ultra-high definition content. The video section is also compatible with full 4:4:4 Pure Color sub-sampling, another feature of the latest HDMI specification. The video section also features SD and HD upconversion and transcoding to 4K Ultra HD. The two HDMI output sockets for the main room and a third dedicated for Multiroom application handle almost all of today’s Ultra HD formats.
Dolby Atmos Surround Decoding
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 9.1.2 or 7.1.4 speaker configuration.
Advanced HDAM Discrete Buffer Amplifier Modules
The AV7702 features our latest HDAM (Hyper Dynamic Amplifier Module) components, which consist of matched precision discrete selected circuit elements on a compact sub-board, instead of conventional op-amp integrated circuits. These advanced HDAM modules provide a full 10 dB of signal-to-noise improvement over earlier HDAM versions, along with ultra wide-band response (100 kHz, -3 dB) for a wide open soundstage with refined details reproduction not to miss any note.
Advanced ISFccc Video Calibration Controls
Certified by the Imaging Science Foundation, the AV7702 features a full suite of advanced video calibration controls that allow precision fine tuning of your HDTV.
Built-in Bluetooth, Built-in Wi-Fi and AirPlay, DLNA
Wirelessly stream your favorite tracks to the AV7702 via the built-in Bluetooth and Wi-Fi. The Bluetooth function features automatic power on and pairing, and up to 8 devices can be remembered. The AV7702 also features dual antennas for even better Wi-Fi and Bluetooth transmission and reception coverage compared to a single antenna. The AV7702 is equipped with Apple AirPlay, which lets you stream content from your iPod touch, iPad and iPhone, and there's also DLNA compatibility which lets you access content from your PC or Mac via your home network. Enjoy a world of internet radio, and listen to your favorite tracks from subscription music services including Pandora, SiriusXM and Spotify Connect (not all services available in all markets).
Easy To Setup, Easy To Use
The handy Quick Setup guide along with the intuitive on-screen Setup Assistant will have your AV7702 up and running with a minimum of fuss and bother. You can even control the setup via your PC's web browser, or use our available iOS and Android apps with your favorite smart device.
New Tablet Apps
In addition to the Marantz Remote app (available for Android and iOS devices), our new tablet app is designed to make full use of your tablet's larger screen area, and is available in Android and iOS versions, as well as a version for the Kindle Fire.
Convenient USB Port
The USB port, conveniently located on the front panel, lets you connect a USB drive directly and stream your favourite audio tracks. You can also connect your iOS device, such as an iPod, iPhone and iPad, and stream music while charging your device at the same time.
Audyssey Platinum Built-in
The most advanced Audyssey MultEQ XT32 (Pro ready) room correction suite adds to the most accurate calibration of the speakers to guarantee that every seat in the room is a ‘sweet spot’ for audio. Audyssey LFC reduces the transmission of low frequency sound through walls to keep a good relation with neighbours, while Audyssey Sub EQ HT cares for perfect integration of two subwoofers in the home theatre setup. Audyssey Dynamic Volume provides real-time volume monitoring and adjustment, to prevent those annoying jumps in volume caused by too loud commercials. It's also great for late night listening so you can hear the audio soundtrack clearly at lower volume levels. Audyssey Dynamic EQ provides precision tonal balance tailoring, so you can enjoy full range sound at any volume level. Audyssey DSX (Dynamic Surround Expansion) lets you add a pair of front wide or front height speakers to your 5.1 speaker system to expand the front soundstage that turns your room into a giant home theater space.
Dual 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.
