Overview
● High sound quality audio media player;
HiFi Bluetooth player audio scheme application, support aptx, APTX-HD, APTX-LL;Udisk playback input, USB audio input, optical input.
● 8-channel power amplifier;
The 8-channel amplifier combines advanced switching amplifier technology. Real-time checking and correcting errors in the switching circuit, adjusting the dynamic effect of the output filter, correcting and amplifying in time, making the amplified sound output smooth, delicate and natural.
● 10 channel digital signal processor;
Used by 2 dual-core high-end Hi-Res audio processing chips, computing power up to 456MHz, the attractiveness of the instrument and the sound separation degree was natural expression.
Sound system application
By optimizing the listening position, passengers can adjust the sound specifically for the front, rear or all seats. Powerful bass reproduction is guaranteed by the front bass technology: Here the woofers are integrated into the vehicle body in front of the passengers.

Functions --- Audio media player
Audio media player with high sound quality
● Bluetooth audio:
Application of CSR8675 in HiFi audio solution, support aptx, APTX-HD, APTX-LL, it supports audio with up to 24bit/48khz and bit rate of 576k bit.
● Udisk playback input:
Support multiple music play formats (FLAC, APE, MP3.WAV. AAC. WMA),
● USB audio input:
More and more multimedia playback devices can be expanded.
● Optical input:
Fiber optic connection can achieve electrical isolation and prevent the transmission of digital noise through the ground wire, which is conducive to improving the signal-to-noise ratio (s/n) of DAC (digital analog conversion).
Features---8 Channel Amplifier
8 Channel Car Amplifier with 10 Channel Digital Signal Processing
● The amplifier ch1~ch6 outputs up to 75 watts per channel into 4 ohms or 100 watts into 2 ohms, class ab, thd<1%.
● The amplifier ch7~ch8 outputs up to 125 watts per channel into 4 ohms or 190 watts into 2 ohms, class d, thd<1%. It can also be bridged into 4 ohms, producing up to 250 watts into 4 ohms or 380 watts into 2 ohms.
Features --- 10 CH digital signal processing
To improve the audio processor, all input and output signals can be routed with great flexibility, parameters are loaded synchronously to ensure filter stability, and then 100% coding efficiency, system developers can use this DSP to meet the actual limitations of the speaker, amplifier and listening environment through speaker equalization, multi-band compression, clipping and AE algorithms, thereby greatly improving the sound quality experience
