In car audio retrofit, the quality of the sound source is the most important factor. Due to the different high/medium/low configurations of luxury cars, the power amplifier of the head unit on some low and medium configuration cars can’t meet the requirements of audiophiles. The sound source part has been processed by default tuning and power amplification during output, and the output is a high-level sound signal.
The function of the audio box is to separate the processing commands of the host for audio data, such as volume, sound effects, etc., and discard the original car power amplifier. It outputs general-purpose optical fiber/coaxial sound signals in the format required by professional audio equipment, thereby completing the conversion of car-specific network data to professional audio data. In this way, the unprocessed original sound source can be obtained, and at the same time, an external high-quality sound source can be added to match with the retrofit aftermarket power amplifier (with digital DSP function, supporting common optical fiber/coaxial signals), thereby bringing a perfect sound modification effect.
