This car audio system is equipped with
a parametric digital equalizer. In this
case, parametric means that it is possi-
ble to individually raise or lower one fre-
quency (GAIN +10 to -20 dB) for each
of the five filters.
The following filters are available:

●

SUB LOW EQ

32 to 50 Hz

●

LOW EQ

63 to 250 Hz

●

MID EQ

315 to 1250 Hz

●

MID/HIGH EQ

1600 to 6300 Hz

●

HIGH EQ

8000 to 12500 Hz

These filters can be adjusted without the
use of measuring equipment. As a re-
sult, it is possible to significantly influ-
ence the in-vehicle acoustics.

Notes on making equalizer

treble, balance and fader to “0” and de-
activate the Loudness function. For
more information on how to do this, re-
fer to the section on “Tone and balance/
fader”.

lected.

your own personal preferences.
