Onchdbfhuu A816 Dual-Core ACM8816 High-Power Digital Bluetooth 5.4 Amplifier Board Audiophile Decoding Remote Control

The fiber optic and coaxial receivers use the AK4118 chip, supporting 16-24bit and 44.1-96kHz sampling rates, offering excellent performance. The high-end digital audio receiver chip supports 24bit/96kHz, features ultra-low jitter PLL, automatic multi-input identification, and provides a clean clock and high-definition audio decoding for Hi-Fi devices. The ACM8816 is an I2S input chip, resulting in an extremely high signal-to-noise ratio. It supports optical, coaxial, USB, and Bluetooth inputs, offering a full range of functions. It features a display screen and remote control functionality for ease of use. Using the QCC3084 Bluetooth 5.4 high-performance chip, it supports lossless high-definition audio transmission, low power consumption, and low latency, easily achieving a high-quality wireless Hi-Fi listening experience. The filter capacitors are audiophile-grade capacitors, and the Bluetooth module is a QCC3084, supporting LDAC lossless transmission, ensuring superior sound quality compared to wired transmission. The ACM8816 is a mono amplifier chip. Our amplifier board uses two ACM8816 chips, one per channel, capable of outputting 300 * 2/4 ohms. The ACM8816 chip produces a delicate, smooth, warm, and richly detailed sound, without the dry, cold, and harsh quality of ordinary digital amplifiers.
