Description
AK4490EQ Dual Parallel Soft Control Board Coaxial Fiber DAC Decoder Board Kit with Display Support DOP DSD
Product Description
AK4118 is a coaxial fiber data demodulation chip. This chip appears in the 10,000-dollar decoder abroad. The price and effect of the chip are far higher than those of DIR9001CS8416 WM8805 and other chips. The greatest sense of hearing is clean, natural and delicate. AK4490 is AKM's fourth-generation decoder chip, and it is also a decoder chip that supports 32BIT 768K. Using original AK4490EQ (2 pieces) + AK4118 The main circuit of electrolytic capacitor signal adopts famous brands such as Philips, ELNA, Panasonic, etc. The main filter capacitor adopts NOVER audio special capacitor with a capacity of 4×4700UF, and adopts full-wave bridge rectifier circuit to ensure strong and continuous power support. The five-ring metal resistor is used for the resistor, and the five-ring metal film resistor with an accuracy of ±1% is used for the main circuit, which ensures a good signal-to-noise ratio of the whole machine. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Top-notch PCB quality. The power supply part of AK4188 adopts the most stable voltage stabilizer chip LT1963EQ-3.3 for audiophiles at present The PCM format supports up to 192K, and the company's U8 daughter card will support DSD64 and 128. Directly display the sampling frequency, intuitive and convenient Support DOP DSD (USB support, fiber coaxial does not support)
