Product details
AK4118 is AKM's latest coaxial and optical data converter chip. This chip is used in various high end DAC. The price of this chip way surpasses the DIR9001, CS8416 or WM8805 and etc. The most obvious character is - clean, natural, and refined. AK4495S is AKM's 4th generation DAC chip, and is the first DAC chip to support 32bit 768K DAC chip. Technically, it surpasses all the AKM43xx series DAC. The chip's analog left and right channel, and the reference voltage use separate power supply, to effectively lower the crosstalk. AK4495S has 4types of digital low pass filter foruser selection. It has newest analog circuit to present a better and higher resolution sound. Digital section wise, it employs an independent 32bit digital processor to provide complete 32b processing. Inside the ship, AK4495S uses AKM's latest switching capacitor filter, greatly lowering the noise floor, realizing extremely low distortion and noise operation. In addition, Audio 4 Pro (TM) seriesDAC chip has excellent sound.
