System comparison - linearity

A frequency response as linear as possible is the prerequisite for sound reproduction true

to the original.

Advantages of the systems

The following advantages characterize the 2 new audio systems:

• Compared to the E36/7, distinct improvements in the low frequency range have been

achieved.

• Due to the dynamically set parameters (adaptive filters) of the Top-HiFi amplifier, the

sound impression is adapted to the driving noise characteristic of a roadster.

• The HiFi and Top-HiFi audio systems can be combined with virtually all radios.

HiFi System

The HiFi audio system consists of following components:

• Radio Business-CD or CID

• HiFi amplifier

• Front left and right low-range speakers (woofers)

• Front left and right high-range speakers (tweeters)

• Front left and right mid-range speakers

• Rear left and right low-range speakers (woofers)

• Rear left and right mid-range speakers

• CD changer (optional)

HiFi amplifier

The HiFi amplifier is designed as an analogue 10-channel amplifier. The 4 input channels

are divided via frequency gates and equalizing filters over 10 channels. The HiFi amplifier

is installed in the luggage compartment trough next to the vehicle battery.

The output power is:

• Low-range 4x40 W

• High range/mid-range 6x25 W

The channels are divided over a 3-way speaker system at the front and a 2-way speaker

system at the rear.
