Audio system for use in motor vehicle, has processor unit arranged such that amplification factor is adjusted for outputting amplified audio signal with sound level that correlates with detected sound level of another audio signal

摘要

The system has entertainment and interrupt audio sources (AQ1, AQ2) e.g. radio player, outputting audio signals (vas1, vas2), and an amplification unit (V) amplifying the audio signals. An output unit outputs the amplified audio signals, and a sound level detecting unit detects sound level of the output amplified audio signals. A processor unit (PE) is arranged such that an amplification factor is automatically adjusted for outputting one of the amplified audio signals with the sound level that correlates with the detected sound level of the other amplified audio signal. The audio sources are selected from MPEG audio layer-3, compact disk player and radio player.
