two. Product details show:

Let us first let us seeAD-7200HDInternal machine design, process level and printed circuit board,(Figure three)YesAD-7200HDOpening map:

It''''''''''''''''''''''''''''''''s a few craftsmanship and complicated, and the multi-layer design printed circuit boards that are exclusively arranged, and the multi-layer design printed circuit boards are full loaded./The input and output circuit of the analog signal,HDMI  4K,2KSignal matrix control switching processing circuit; HD, standard deficiency decoding circuit and various audio effectsDSPPost-processing circuit, intelligent machine control circuit, built-in high-definition video play circuit; wirelessWIFIBluetoothAPTXLossless transmission（Require additional Bluetooth receiving moduleBTU-1)Circuit, etc. In order to help you have a probably understanding of the functions of each large-scale chip, I hereby labeze the functional use of each chip for everyone to understand.

(Figure four）

The author noted that the front end of the machine is a large metal shield box. It is shielded in the box that is a power supply power supply and a digital display circuit of the panel. Because the machine power supply and the digital liquid crystal display circuit are theoretically There is a suspicious of radiation interference, so that the designer specially designed this metal shield to improve the anti-interference ability of the whole machine. From this point, it is also possible to see the designer''''''''''''''''''''''''''''''''s ubiquitous high fidelity!

Three: Let''''''''''''''''''''''''''''''''s take a focus on talkingAD-7200HDrelativelyAD-7100HDIIWhere is the significant upgrade and strengthen:

1. From the hardware circuit,AD-7200HDIncreased high-definition player in the machine, and the supporting sets also increased accordingly.USB（2.0）interface

（Figure 5）

This interface can be directly connected to externalUDish or external hard drive play movies or songs, provide you with simple and convenient operations and huge audio and video resources in use, greatly enriched the playability of the machine!

（Figure 6）

The author uses the actual use to verify the plug-in hard disk play1080PWhen the movie is large, the playful voice effect is very smooth, there is no slight card phenomenon! insertUWhen the disk is played on the network, the sound quality of the sound is very fascinating, and the effect is directly in the same external environment.CDThe playback effect of the disc, this is also one of the people who are discouraged.

2. Specially designed and extremely powerful wirelessNetwork connection andWIFIconnect,comprehensivesupportMiracast,DLNA,AirplayWaiting for a variety of current popular mainstream soundsWireless transmission function. This feature is extremely useful and interesting: I used my Android phone when I tried this feature.VIVO Xplay3Scell phone:

（pictureseven）, First enter the phone''''''''''''''''''''''''''''''''s settings page to find multi-frequency interaction（Apple phone is also known as wireless push）Point open, then click on the scanning display device, a name called TianyiAD-7200HD DCE5 is connected to the device name, and then immediately immediatelyVIVO Xplay3SShow screen mirroring on your phone to me55-inch Sony HD TV, the effect is very eye-catching, very shocking!

（Figure eight）

Speaking of this, the author does not help but remember that an international brand is "wireless transmission, unparalleled" in an online big matter, and actually uses you to discover their mythical advertisement actually only wirelessly." Play stored in iTunes and iPhone / iPod Music content in the Touch / iPad...... "And you can''''''''''''''''''''''''''''''''t synchronize wireless push video. so"UnparalleledTechnology and TianyiThe wireless transmission technology of the AD-7200HD is far away! AD-7200HD can easily（Whether it is Android, Windows system or an Apple system）The content mirror on the screen is on the large-screen TV. This feature views large-screen large screens with mobile phones in the wired network and wireless Wi-Fi, there is unparalleled practicality and convenience. The picture is smooth and clear and natural. This feature also fully verifies the ability and practical functions of domestic HD equipment with high-definition decoding amplifier technology in today''''''''''''''''''''''''''''''''s world.

3. Considering that many home the theater has both TV sets, there are two HDMI output interfaces for the convenience of wiring. Before the AD-7200HD, Tianyi''''''''''''''''''''''''''''''''s power amplifier is only one HDMI output, so many consumers are ill. This time, Tianyi finally realized in the AD-7200HD.6-way HDMI1.4 interface input, 2 HDMI output.Make the terminals of the input and output increase, practical and convenient.

4. Comprehensive support4K, 2K play, the picture shows crystal clear texture, clear and incomparable. CooperateDolby TrueHD,Dolby Digital Plus,DTS MasterWaiting for high-definition audio, dedication to the audience''''''''''''''''''''''''''''''''s vocal painting effect is indeed uniform and wonderful!

The above four points have improved improvement, which is a fresh vitality of the third-generation HD decoder, so that its scientific and technological content and practicality are greatly improved.

It''''''''''''''''''''''''''''''''s undeniable,AD-7200HDHave high-definition decoding capabilities with considerable, practical and convenient. It can read smoothly Dolby TrueHD,Dolby Digital Plus,DTS Master,DTS HI RESWait for HD format movies,HD resolution is4K, 2K technology, ownedBuilt-in HD player,supportexistLine network connection and WiFi connection,comprehensiveSupport Miracast, DLNA,AirplayWirelessSound, videoTransmission function;haveThree-way external USB interface, support local U disk / hard diskAudio and videoPlay function;have6-way HDMI1.4 interface input, 2 HDMI output;These features are enough to indicate that the AD-7200HD high-definition decoding preamp code is currently the Church of the domestic high-end home theater. If you are a strict requirements for a function, sound quality sound is strict, looking forward to a good compatibility in a set of equipment and listening to non-destructive music, and can play non-destructive Bluetooth, support a variety ofwirelessSound, videotransmission, The sound of coming with HD playback capabilities, this4KHD cinema decoder will be your ideal choice!
