7.33 Loudness
Alternatively the 8 input pins can connect to 2 stereo signals with common mode rejection
and 1 stereo signal or 1 mono signal with common mode rejection or differential input.
The input audio level of external sources can read out via the I
information is available on a logarithmic scale. In radio mode the AM or FM modulation
index is available in the same way.
The volume/balance control is used for volume setting and also for balance adjustment.
The control range of the volume/balance control is between +20 dB and 75 dB in steps
of 1 dB.
Dynamic volume compression is available for external input sources. This option is
generally used for audio from CD or other digital formats to reduce the very high dynamic
range of these signals into a range suitable for the car environment.
The bass tone control stage controls the low audio frequencies with a modified shelve
curve response. The control range is between +14 dB and 14 dB in steps of 2 dB. Four
different filter cut-off frequencies can be selected.
The treble tone control stage controls the high audio frequencies with a shelve curve
response. The control range is between +14 dB and 14 dB in steps of 2 dB. Four
different filter cut-off frequencies can be selected.
An integrated loudness function can be activated which controls bass and treble in relation
to the user volume setting. The control range of the bass frequencies is limited to 20 dB
and the optional treble range to 4 dB. Different volume ranges can be selected for the
loudness control.
Four of the eight input pins can connect to:
– 1 stereo signal with differential input (CD-symmetrical)
– 1 stereo signal with common mode rejection (CD-2) and 1 mono signal (e.g.
– 2 stereo signals (AUX and AUX-2)
– 1 stereo signal (AUX) and 2 mono signals (e.g. NAV and BEEP)
The other four input pins can connect to the same options and allow additional
connection to:
– 1 stereo signal and 1 mono signal with common mode rejection or differential input
BEEP)
