Top Hifi Audio System

Top HiFi Audio System
The Top HiFi audio system features a 10 channel amplifier with digital signal processor technology for sound control. The Top HiFi amplifier is controlled via the two radio analogue audio signals.
The Top HiFi amplifier features a digital input for the CD changer. The digital input is only used for the BMW Business CD radio and CD changer combination. The 10 loudspeakers are directly connected to the 10 output channels of the Top HiFi amplifier. The active frequency gates for adaptation of the loudspeakers are built into the amplifier.
Depending on the radio, various functions can be called up. Sound control functions such as volume, bass, treble, fader, GAL, spatial sound simulation etc. are formed in the Top HiFi amplifier. The 7 band graphic equalizer can only be used in connection with the CID radio.

Top HiFi Amplifier





A fuse is added to the familiar Carver Top HiFi amplifier from the (E85) Z4 but is otherwise installed in the (E83) X3 SAV without further modifications.
However, special Carver woofers with increased cone excursion are used in the (E83) X3 SAV that are used in the (E85)Z4. The space available in the (E83) X3 SAV and the resonance volume in the side sill enables - the use of the central bass principle. e
The central woofers in the Top HiFi audio system are simply adapted to the increased voltage level of the bass end levels (8 . impedance). The amplifier delivers 6 x 20 watts, 2 x 40 watts and 2 x 100 watts.
