Improve audio source quality

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.

Elevate the Land Rover Jaguar audio system effortlessly with ‘Pre-amplifier Interface Box for Land Rover Jaguar’. This innovative interface box serves as the key to enhanced in-car audio experience. Paired with our premium Land Rover Jaguar AMPLIFIER, it provides a immersive audio upgrade.

Optical fiber decoding non-traditional high-to-low conversion

OST optical fiber interface, complete digital transmission; original car control interface; car regulations,audiophile grade materials; non-destructive upgrade, no trace of restoration; standard SPDIF fiber coaxial output.

In premium vehicles, the ‘Pre-amplifier Interface Box’ detects the audio signal within the MOST25 data stream. This lossless and interference-free communication allows music to be output in the highest quality digital stereo signal. Thanks to an optical digital output, signal processors and DSP amplifiers with a digital SPDIF input can be fed with a perfect audio signal.
