HI-FI Wireless Digital Audio Transmitter-Receive
Super UII wireless HIFI digital audio decoder
B version
Freedom of the future will be dominated by wireless digital. In studio-grade audio and computer audio HIFI field is no exception.
Referrals according to the following major wireless HIFI digital audio decoder Super UII.
Super UII is a market among a variety of digital wireless audio quality and sound the best. Not the most reliable web-based, and supports continuous mode that can direct transmission of real-time high-fidelity wireless uncompressed PCM digital audio signal. Referred to as the audio bridge. (You might well ask a good living in network-based, network-based or not living in the good? OK!)
You can interpret it this way. That is, when several or several sets of wireless digital audio Super UII when the bridge at the same time. Each receive a set of audio is completely synchronized. This is very important. Left and right channels to ensure stereo or multi-track simultaneous recording and playback accuracy, the same pace; and the use of live audio web-based multi-use bridge in the side when possible with each set or each set of tracks and track that there is no synchronization between. There is a serious response. As the network is slow and even there the voice of chaos. Just imagine. When you left-channel audio voice has begun, and the right channel will have a second voice, then the effect will be able to listen to).
The main application of Super UII:
1: The sound quality is very high. Requirements of weak extremely low distortion audio signal to large dynamic amplification. Requirements to multi-channel audio transfer. (Eg: 5.1 channel, 7.2 channel high-fidelity audio, etc.) requirements of electromagnetic interference in the environment is very complex long-distance transmission of audio signals. Must be wireless, and real-time waveform of the digital audio signal integrity test system. Some audio radio relay station, home wireless AV audio-visual system. Part of the military use of broadband transmission equipment, such as audio communication.
2: When launching and receiving more than 20-100 km distance, the (necessary for an additional power amplifier 2.4Ghz). Such as high-fidelity audio aeronautical mobile satellite communications. Distant from the frequency analysis of the language of animals, as well as Internet access system of the seismic survey.
3: You can live in a computer-centric wireless audio and video systems, as well as wireless network PC-HIFI audio download, you can live in a wireless Internet surveillance monitoring system.
4: can be used in wireless digital headphones, digital wireless microphone, wireless digital amplifier, wireless digital audio, wireless digital speakers, wireless Internet, wireless kalaok Office, wireless, wireless ......。
Super UII when you have wireless HIFI digital audio decoder, your personal computer (PC), TV, AV, CD drive, MD machine, DVD, VCD, LD, mobile phone, Iphone ...... etc. music will become more perfect platform audio player.
Note: Because, Super UII transmitter and receiver with built-in high gain of 23dB then (2.4GHZ) radio frequency (RF) amplifier circuit. Super UII when the receiver process in the mobile use. Transmitter in order to ensure constant communication with the wireless receiver. The launch of the state of the receiver will automatically adjust the transmission power of its own. This will lead to the launch of transmitters larger peak current. The largest can reach 500mA. Therefore, to draw your attention to the. Please do not arbitrarily replace the random power adapter with power supply. At the same time, the best to keep your receiver or transmitter are in a static state. Here you should see.
Now available on the market 2.4GHZ USB transmitter is USB Interface internal power supply. USB transmitter and no external antenna. Therefore, the launch distance is very difficult to stabilize in the 15 meters outside. Even if you increase the antenna. Ability of radio waves through walls, or very poor. Therefore, to launch and acceptance of distance is to pay the cost of current power (oh, the very power).
Super UII can fully adapt to the machine's automatic seamless frequency hopping. Wireless transfer of uncompressed digital audio phenomenon is 1:1. Super strong anti-interference ability. Own 38 automatic digital frequency channels (able to provide up to 125 optional frequency models, the need for reservations). Fully meet the needs of multi-frequency and frequency hopping. Do not interfere with each other, can be trimmed away outside mirrors harmonic frequency bands;
Transmitter coaxial, fiber optic input, USB input and digital audio receiver Coaxial, AES3, optical, BNC output impedance are standard 75Ω, the impedance of the RF 50Ω;
Transmitter and receiver on the USB support for Plug and Play, without AD or DA conversion, or any form of compressed digital audio signal. 16bit to 24bit support arbitrary bit audio sampling frequency of 8KHz, 22KHz, 32Khz, 44.1Khz, 48Khz, etc., that is 8 to 48KHz sampling frequency, such as arbitrary number of audio signal input, up to 48khz sampling 24bit/44.1K or wireless or cable digital audio output sampling rate can be equal to or greater than the real CD, HDCD, DVD to restore the music.

Super UII-wide radius of the direction of the launch distance and maximum effective range can reach 100 m -300 m, (general 0dB omni-directional antenna in the open areas, firing points, 2 meters high from the ground, visible range can penetrate floors , 3-5 over the cement block walls can still pass through, Super UII in indoor firing range and acceptance of space radius of 60 meters, SPDIF-II than a lot of great shows added after 2.4GHZ RF power amplifier capacity through walls super, above all for the launching and receiving in a static state at the time of the test results) in the case of the need for its launch from farther than 500 meters -100000 m
