Preamplifier interface box for BMW is a premium sound treatment solution that converts the Ethernet signal into digital output. It aims to improve sound quality and functionality without the need for extensive modifications or rewiring. It includes two Toslink outputs and two coaxial outputs, delivering a high-bit-rate digital signal directly to your amplifier or DSP via optical or coaxial connections. Compatible with all BMW ID7/ID8 system.
Installation and debugging
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.
Lossless upgrade better quality
Keep all the functions of the original car: Bluetooth, WIFI, USB, DVD/CD, radio, reversing radar, navigation, favorites, parking reminder and other sounds and functions.
Upgrade your BMW audio system seamlessly with our “Pre-amplifier interface box for BMW .” This innovative interface box serves as the bridge to elevate your in-car audio experience. Pair it with our premium BMW AMPLIFIER for a crystal-clear sound upgrade.
