switch the “Graphic EQ” to “Parametric EQ”.
Click the Graphic EQ key [ ] to switch the
“Parametric EQ” to “Graphic
EQ”.
* The gain is adjustable but the frequency
and Q value are fixed in the Graphic EQ
interface. The frequency, Q value and
gain are all adjustable in the Parametric
EQ interface.
Description of frequency combination setting function
After the PXE-R500 device setting sound source signals enter the audio processor, the volume
frequency of various output channels will be divided. The sound source volumes in the channel can be
adjusted to perform sound mixing and frequency mixing. In the passive input mode, the frequency
division will be set from PC. In the active input mode, the frequency division will be set from the main
device of the vehicle.
