@ Graphic equalizer tone control knob
[5-band graphic equalizer]
This enables control of the frequency response at the
following 5 points: 60 Hz, 250 Hz, 1 kHz, 3.5 kHz and 10
kHz. Use this to adjust the sound to the tone quality of
your preferrence, bearing in mind that the acoustic inside
a vehicle differ according to the interior decor and other
factors.
When
each knob slid on the '+" side, the sound
corresponding to it's frequency is emphasized, and when
it is slid on the ''—'' side, the corresponding sound is
attenuated. For example, depending on the position of
speakers, the treble may lack in strength but this can be
compensated
for if each of the 5 knobs is adjusted
properly.
