ෆ Product Description

Description:
AK4118 is AKM's latest introduction as a coaxial fiber data demodulation chip. This chip appears in the million-level decoder abroad, and the price and effect of the chip are much higher than that of the DIR9001CS8416 WM8805 chip. The maximum sense of hearing is clean, natural, and delicate. The AK4495S is the fourth-generation decoder chip from AKM and the world's first decoder chip that supports 32BIT 768K. It is technically superior to the AKM43XX series. The left and right channels of the analog section of the chip and the reference voltage are independently powered, which effectively reduces crosstalk. The AK4497 uses AMD's newly developed OSR Doubler filter THD+N: -115dB,DR, S/N: 127dB (130dB in parallel), PCM sampling rate up to 769K, DSD sampling rate up to 22.4MHz, and AKM's newly developed OSR The Doubler filter greatly reduces the impact of noise shaping and enables a very low distortion music playback experience. At the same time Audio 4 Pro (TM) series chip has excellent sound performance, this is an important reason we choose this chip!

Specification:
1. Adopt original dual-chip AK4497EQ+AK4118 (op amp 5532 and NE5534, free to change the op amp)
2. Electrolytic capacitor signal main circuit adopts Philips, ELNA, Panasonic, and other famous brands. The main filter capacitor uses NOVER audio dedicated capacitor capacity 4×6800UF, and adopts full-wave bridge rectifier circuit to ensure strong and continuous power support.
3. The resistor uses five-ring metal resistors, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio.
4.PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
5. AK4188 power supply part adopts the most stable voltage regulator chip LT1963EQ-3.3
Fiber, coaxial, USB input signal is switched by encoder switch
6. The PCM format supports up to 384K, and the company's U8 daughter card will support DSD64 and 128. Because of the AK4118, playing a file above 192K does not display the sampling rate.
7. Imported gold-plated luxury RCA seat
8. Fully balanced dual op amp design with balanced XLR output, RCA single-ended output
9. Direct display of sampling frequency, intuitive and convenient
10. Remote control supports input switching and volume adjustment
11. The AK4497 uses AKM's newly developed OSR Doubler filter for better dynamic range THD+N: -115dBDR, S/N: 127dB (parallel, 130dB)
12. Machine size: 330*275*85
13. Weight: 4 kg
