1. The latest group decoding system in the United States
Let's understand the powerful compatibility of ASR70. Why do we say that it has strong compatibility? Because this machine's internal decoding system uses the US advanced group decoding system. So what is group decoding? What is the difference with traditional decoding? Here it is necessary to explain briefly-traditional decoding is usually called integrated decoding or single-chip decoding. It is generally composed of one or two integrated blocks. Because the digital format controlled by the chip is too large, it is not professional enough to work, and the data processing is not accurate enough, resulting in deterioration of sound quality. Mainly there are certain problems in channel separation, service life, stability and the restoration of detailed signals. The group decoding effectively solves these problems, why can it solve these problems? That is because the group decoding has changed the working mode of traditional integrated decoding, because the group decoding is completed by more chipsets to complete the interpretation of digital encoding, that is, through a special CPU to classify digital signals in different formats, and then And then sent to the corresponding decoding chip for decoding, and then input to the relevant system of the central machine through the corresponding channel for signal processing. (Because the group system has a precise division of labor between the various parts, its data processing is more accurate (signal loss is less than 5/10000), and the processing speed is also faster (decoding processor digital stream flow can reach 32bt), average The service life is 5.6 times that of integrated decoding, reaching 196,000 hours.)
2. Professional digital sound calibration system, perfect restoration of real sound effects
The ASR70 central unit has a built-in professional digital sound calibration system (SPEAKER MOOD and CH MOOD on the front panel), which can make different adjustments according to different listening environments, accurately control the sound energy release strength of the speaker, prevent reflected sound, and achieve good The listening effect can achieve a good listening effect no matter in any place or in any space. (There is a problem that consumers can’t ignore when buying audio, that is, whether a good set of audio can achieve a good listening effect after buying home. Most consumers have encountered the same when buying audio. One problem: I feel more satisfied when I listen to the scene, but often I can’t get the effect I heard in the on-site audition after buying it home. Because all the audio product stores are developed in the professional audition room , And our general home decoration is impossible to have the conditions of a professional audition room. Acoustic sound absorption conditions are very poor, the sound transmission capacity forms a reflected standing wave, which produces a turbid resonance, so I can’t get a good hearing when I go home. Sound effects.)
3. Professional-level karaoke, restore the real sound effects on site to add exciting entertainment life for you
AVANCE ASR70 digital power amplifier is equipped with professional-grade karaoke function, and installing karaoke function inside the amplifier is a technical problem for any audio company (because the authoritative DTS and Dolby Corporation have repeatedly tested and believe that due to singing karaoke In the work of the circuit, it will produce a lot of harmful radio waves that affect the decoding circuit and reduce the quality of the power amplifier. It should not be used in combination with the decoding circuit). Therefore, in accordance with international practice, most imported brands do not design karaoke to ensure sound quality. However, karaoke is an indispensable function for Chinese home entertainment. Therefore, the AVANCE does not hesitate to solve this problem. ASR70 has a professional karaoke built-in and is independently installed on the back end of the amplifier (ie, the back end).
4. 1. Humanized communication interface. .
This AVANCE ASR70 digital amplifier has many intelligent and user-friendly designs. For example, every time we turn on, the computer CPU chip inside the machine can automatically search (automatic tracking memory function), according to the disc you are currently using. It is very convenient to analyze the film and find a listening parameter suitable for this disc style.
AVANCE ASR70 digital power amplifier can well grasp the playback requirements of digital home theater. It has a built-in independent CPU intelligent chip, automatically detects the input signal, and automatically restores the sound system to 30dB when it is turned on, so that the power amplifier can avoid sudden power damage at startup. In addition, through the intelligent CPU chip, the AVANCE ASR70 amplifier has not set eight DSP sound field effects, which can be applied to different use space environments, so that you can use it more effortlessly, and get better sound effects.
This ASR70 power amplifier is completely different from other imported brand power amplifiers. Its operation is very simple, with a humanized AUTO operating system (operation: rotate it on the function knob at will, because there will be no system operation problems and no sound, no need Look for the manual, not to mention the after-sales service personnel, just press this button lightly-AUTO intelligent regulator, then the CPU chip inside the amplifier will be within 1 second, whether it is music appreciation or home theater effect All are restored to the best state, the operation is quite simple, completely different from other imported brands. (Explain the biggest problem of other imported brand power amplifiers-the operation is cumbersome, the average consumer cannot use it at all, and many functions will be idle.)
5. Just press the DIRECT button, the group decoding instruction CPU inside the central machine will automatically turn off the theater circuit, video system and all switches that have nothing to do with the sound quality, and switch to pure Hi-Fi state in 0.1 seconds, which is quite a fever Pure power is used in the work to make the sound more pure, soft and delicate when the music is played back.
