Portable ES9018K2M DSD128 PCM32BIT 384KHz Lossless HIFI Decoder MAX97220 Headphone Amplifier Chip

HIFI audiophile audio decoder DAC mobile phone computer sound card earphone USB asynchronous connection sound amplifier headphones Product Description 1: The use of USB asynchronous programme, accept computer and mobile phone USB audio data after the CT7601 asynchronous USB chip into high-precision IIS data to the ES9018K2M decoder chip, 32bit decoder chip so that the output dynamic range of the DAC decoder indicators can easily reach more than 120dB, large dynamic range makes the sense of listening to the fullness of the separation of the degree, the space! Very good! 2: the use of ESS classic chip, model ES9018K2M, the decoder chip sound-price ratio is very high, support for PCM32bit 384k, DSD128 source code directly, the chip DNR 127dB, THD + N-120dB, indicators far beyond the range of human ear hearing, listening to a very translucent and full-bodied, is a rare generation of the classics, recognition, visibility are very high! The chip has been adopted by a number of world-famous aircraft, much praise! 3: The use of ON Semiconductor M A X97220 independent earphone amplifier to drive the headset powerful thrust easy to drive your headphones, measured output level of 2.7Vrms@32R@1KHZ, 2.9Vrms@130R@1KHZ. 4: The use of 32-level volume adjustment, by the MCU control ES9018Q2M decoder chip volume, adjusted without noise, improve the purity and fidelity of sound. Long press/tap can achieve the volume up or down the machine is designed with a key to eliminate the sound button, press that eliminates the decoder volume, press again to restore the volume, simple and practical. 5: Warm tips: the decoder is a digital audio signal into an analog audio signal, analog audio signal used to promote the headset sound, this decoding scheme using USB asynchronous data and 32bit high-precision decoder chip ES9018Q2M as well as ON Semiconductor MAX97220 dedicated ear amplifier chip, this scheme with the player to open the exclusive/push mode can be bypassed by the mobile phone or computer system Frequency uplift, because the system frequency uplift on the sound quality is seriously degraded, so the use of this programme can be obtained than the mobile phone computer more high-definition sound. 6: The use of aluminium alloy anodic oxidation process, PC lens transparent window, the value of the sky.
