Overview of TY-1CD Hi-Fi CD Laser Player
1. Appearance characteristics
The appearance of TY-1CD is the same as the previous flagship products of Tianyi HI-FI. It is made of classic black and white all aluminum alloy, which expresses Tianyi''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s consistent simple and atmospheric design style; many exquisite curved designs outline a full-strength shape; the angular design reveals a tough and heroic in elegance.
The body shell adopts anodizing treatment technology to ensure that the color of the body stays as bright as new for a long time. The fine LCD dot matrix screen is connected to the machine compartment, and the exquisite and small function buttons are connected in a line, and coupled with a refined aluminum alloy remote control, the performance in both texture and hand feel is satisfactory. These details are not One does not give people a luxurious and elegant visual impact, and is full of models of flagship products.
2. Materials and circuit design
The output interface of TY-1CD adopts 24K gold-plated terminals, which can reduce fretting corrosion of metal contact surfaces, thereby reducing contact resistance and increasing current conductivity. At the same time, it can effectively enhance the stability and integrity of signal transmission and reduce signal transmission. The generated attenuation value avoids the instability caused by the high attenuation value to the high and low frequency signals, and minimizes the signal loss.
The imaginative decoding core ”: adopts the flagship chip ESS9028 of American ESS Company, this chip is known as “the industry''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s top digital audio decoding chip”, its letter The noise ratio is as high as 129dB, and the total distortion is less than -120dB. It supports up to 32bit/384kHz high-spec input signal, supports multiple high-definition audio format decoding, and the performance is amazing! In addition, ESS9028 can transmit and play 3.078mhz DOP directly via coaxial and optical fiber(DSD, SACD), This is beyond the reach of other decoding chips. The ESS9028 chip can guarantee super resolution, the sound field is relatively open, the real scene and natural overtones, the sound is exquisite and embossed, the music taste is strong, the texture is very good, and the low frequency expression is extremely strong.
Military-grade clock system: In order to maximize the performance of the DAC chip, Tianyi has specially customized a top high-precision clock system module CS2000 from Cirrus Logic in the United States. This clock system uses programmable △—∑ fractional frequency analog PLL(Phase locked loop)Frequency synthesizer, to stabilize the frequency synthesis/clock generation of the reference clock, and generate a clock with lower jitter than the external noise synchronous clock at a frequency as low as 50Hz. The digital PLL can be used to generate an analog phase-locked loop multiplication factor to ensure a reference frequency of 8~75MHz, an output frequency of 6~75MHz, an input synchronization clock of 50Hz~30MHz, and a jitter suppression angular frequency of 1Hz. The more unique feature of CS2000 is that it can provide clock generator and clock cleaning functions at the same time with a single IC. This integration reduces the number of components and board space required by the audio system. Compared with other current solutions in the industry, this series of products can greatly reduce Jitter(Jitter)It is an ideal choice for professional audio, high-end consumer market and mainstream consumer audio/video applications.
Operational amplifier with excellent performance: The I/V conversion circuit operation amplifier adopts TI''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s top fully differential operational amplifier OPA1632, which can reduce even harmonics, reduce common mode noise interference, and maximize the high-fidelity performance indicators of balanced transmission signals; The balanced-to-unbalanced circuit op amp uses TI’s top bipolar op amp OPA1612, which is a high-performance, dual-channel, bipolar input audio operational amplifier with distortion as low as 0.000015% and noise density as low as 1.1nV /√Hz!
Selected high-end customized capacitors: The filter capacitor uses ELNA high-capacity and high-quality capacitors, and the signal coupling capacitor uses ELNA audio dedicated capacitors, which provide strong guarantee for soft and flexible low frequency, pure and warm intermediate frequency, and delicate and transparent high frequency.
High-end customized movement: As an indispensable part of the CD player, the designer finally selected this Tianyi customized movement after more than 20 repeated trials. The overall structure of the movement is firm, reliable and precise, and the accuracy of reading discs is extremely high. With the addition of a metal shock-proof base, it has an excellent shock-proof buffering effect. At the same time, it effectively suppresses self and external vibrations so that the optical head disc reading system reduces shaking and reduces The occurrence of error codes improves the accuracy of reading discs.
Three, functional characteristics
In order to satisfy audio players'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' more advanced playing methods of CD players, the output part of TY-1CD provides two parts: analog output and digital output.
The analog output part includes two sets of unbalanced outputs and a set of true fully balanced stereo analog audio outputs. These three sets of analog output terminals have analog output filter circuits optimized for group delay. Advanced audio players know that the true fully balanced output sound is more transparent and fuller than the unbalanced output, and the sound field is wider. In the amplification process, balanced transmission uses the principle of phase cancellation to minimize other interference during audio signal transmission.
The digital output part includes a set of coaxial, optical and AES/EBU digital audio signal output. AES/EBU output port is not common, only a few Hi-End grade CD players are equipped, through this interface, various digital audio equipment can exchange digital audio data, timing information, control information, etc., and this transmission method The anti-interference ability is extremely strong, providing better performance for the back-end power amplifier equipment.
Four, sound characteristics
