HiFi system
The Hi-Fi system, custom built for your cabin, is made up of:
A high power DSP (Digital Signal Processing) digital amplifier.
A subwoofer bass box (30 Hz - 100 Hz).
8 specific loudspeakers.
An MP3 player.
Adjustment in CD or radio mode
The basic functions remain the same as those for the radio.
No extra adjustment is necessary.
However, to make the most of your Hi-Fi system, you are advised to adjust the audio functions Bass (Bass), Treble (Treb), front/rear balance (Fad) and left/right balance (Bal) to position O, and Loudness (Loud) to position ON when listening to a CD and position OFF when listening to the radio.
Your system also provides Dolby surround sound with the Pop, Rock and Classical ambiances.
Note: In the event of poor reception of an FM stereo signal and/or mono source, deactivate the musical ambiances.
