1, a device that restores information from its encoded form to its original form.
2, TCC760 decoding chip, with a powerful 32-bit ARM940T reduced instruction set processor core, the main frequency up to 140MHz (Philips PNX0102 decoding chip is using 60MHz ARM7 processor core, The most common Sigmatel 3520 chip has a main frequency of 75MHz) and is equipped with a large capacity of 64Mbit SDRAM memory.
3. SAA7350 According to the second-hand audio equipment network query "miss 25 decoder" generally refers to the CD25 series decoder, SAA7350 is a digital audio decoder chip produced by Philips, which can realize the decoding output of CD, LD and other digital audio signals.
4, the United States miss 121 and 321 decoders refers to the encoding and compression of music signals.
5, miss 860xcd machine is used four PCM4 1702 decoding series of D/A chips. wadia 860XThe version is 240V voltage, the cd player uses the first audio advanced turntable, which can be used independently as a turntable, but also independently for decoding, of course, as the front direct drive after the stage is also fresh and rich.
6, chip decoding is a special hardware responsible for video coding decoding, this is the basic function, there is nothing to say, look at the literal meaning you can understand. There are many encoding methods, of course, the centralized decoding method integrated in the specialized decoding chip may mainly deal with several corresponding decoding mechanisms.
ad1864 decoding chip good. The ad1864 chip has excellent sound performance, with a smooth, clear, positioning sense of style. It can produce a balance of high and mid-high notes, but also has a rich bass, sound volume, heavy bass significantly. In addition, it also has an excellent sense of proximity, which is amazing.
OK. Excellent sound quality: The 1792 decoding chip has excellent sound quality, with high resolution and low distortion, which can restore a more realistic audio effect and provide a better sound quality experience.
OK. ad1865 decoding chipIt is a regular commodity inspected by the market supervision Bureau, so it is good. The main board made of k752 material has a long durability.
AD1865 is the analog to digital chip of Analog Devices, which is a famous chip for music enthusiasts and has a high reputation in the field of hi-fi music. It is said that this is an R2R D/A chip full of vinyl charm, which is used by many expensive European and American brand CDS or decoders.
The cost performance is very good. Better quality assurance than many DIY boards. Thousand-dollar Dacs are preferred. The sound is relatively warm and the density is OK; There is a certain amount of spaceInspiration, but the big dynamic still has certain limitations. As a daily listening song (especially HIFI female voice) especially suitable.
ad1861 decoding chip is the latest chip, after upgrading, many performance has been improved. AD chip is a bridge between digital and analog. The choice of AD chip directly affects the final performance of the whole link. AD chip has many indicators, we need to choose according to their own needs.
OK.Digital interpolation filter: The chip has a built-in digital interpolation filter, which can process and optimize the input digital audio signal to provide a smoother and more accurate audio output.
Strong flexibility, good sound quality, etc. The ad1955 decoding chip supports a variety of digital input formats, including I2S, PCM, DSD, etc., and can adapt to different audio source devices. The sound quality of the AD1955 is excellent, with a high degree of resolution and precision, and the ability to present rich, delicate audio details.
ad1955 The decoding speed is slow, and the file is prone to error after decoding
