There are 31 sections of EQ that can be adjusted.
When the mouse moves to the serial number position,
press on to drag up and down to adjust the gain of the
equalizer and drag left and right to adjust the frequency
of the equalizer; and when the mouse moves to the
small blue boxes on the left and right, press on to pull
left and right to adjust the Q value of the equalizer. The
frequency, Q value and gain can also be set by directly
inputting values, rolling the mouse wheel and pressing
the up and down keys on the keyboard.
1. Frequency adjusting range: 20Hz to 20kHz;
2. Q value adjusting range: 0404 to 28852; and
3. Gain adjusting range: -12dB to +12dB.
When EQ is adjusted, that is the through equalization
button
【 】 appears, click the “Through
equalization”or through “small dot” to disable all
the equalizers of the current channel; and click the

Frequency Combination Setting Function Introduction
After the sound source signal set by the PXE-0850X machine enters into the audio processor, the frequency is divided
into the volume of each output channel, thereby achieving the aim of audio mixing and frequency mixing by adjusting
the volume of each sound source in the channel. Under the passive input mode, the frequency division is set by the PC
terminal; and under the active input mode, the frequency division is set by the host of the original vehicle itself.
Example 1: the low level of the host of the original vehicle and the low level of the external CD machine are input at
mixed frequency, and the stereo is output at full frequency.
