Fuhjythy Portable Headphone Decoder Amplifier Lossless HiFi Decoder Max97220 Headphone Amplifier Chip

3: 32-level volume adjustment is adopted, and the volume of the ES9018Q2M decoding chip is controlled by MCU. There is no noise when adjusting, which improves the purity and fidelity of the sound. Long /tap can increase or decrease the volume. There is a one-key sound elimination button designed in the machine. it once to the volume of the decoder, and it again to restore the volume. It is simple and practical. 2: Adopting classic chip, model ES9018K2M, this decoding chip has a very high sound-price ratio, supports PCM32bit 384k, DSD128 source code direct playback, the chip DNR 127dB, +N-120dB, the index is far beyond the human hearing range, the hearing is very clear and , it is a rare generation of classics, with very high recognition and popularity! This chip has been adopted by many world-famous machines and has been well received! 1: Adopting USB asynchronous solution, receiving USB audio data from computers and mobile phones, and converting it into high-precision IIS data through CT7601 asynchronous USB chip to ES9018K2M decoding chip. The 32-bit decoding chip allows the dynamic range index of this decoder output to easily reach more than 120dB. The ultra-large dynamic range makes the fullness, separation and spatial sense of hearing very good! Very good! 4: Warm reminder: This decoder converts digital audio signals into analog audio signals, and analog audio signals are used to drive the headphones to sound. This solution can bypass the upscaling of the mobile phone or computer system when the player opens the exclusive/push mode. Because the system upscaling seriously damages the sound quality, using this solution can obtain higher-definition sound than mobile phones and computers.
