Fiber Optic MOST DSP Amplifer
BMW original head unit system come with MOST fiber optic output but does not come with RCA output, when doing the audio system upgrading, it can only convert the high level audio signal to low level audio signal to the amplifier, which will cause signal distortion, leading the missing of details of sound and compression of dynamic range
To solve the problem, the best solution is to get digital audio audio output from original MOST fiber. Our amplifier connect to original headunit through original fiber optic socket, fiber digital interface will convert the MOST output to IIS digital audio perfectly, to guarantee the high quality audio output.to ensure less signal loss and best audio source.
