This device has a parametric digital equaliz-
er. In this case, parametric means that in each
of the three filters, one individual frequency
can be emphasised or reduced (with a gain
of +8 to -8 dB).

The following filters are available:

●

LOW EQ

32 - 200 Hz

●

MID EQ

250- 1,600 Hz

●

HIGH EQ

2,000 - 12,500 Hz

These filters can be set without using any
measuring instruments. It allows the sound
properties in the vehicle to be significantly
affected.
