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.

The PXE-0850X machine can adopt the PXE-0850X
wire controller for tuning and setting. Please connect
the wire controller to the machine correctly before
usage and make sure its normal start.
Note: the wire controller and the tuning software
cannot be used at the same time.
Startup Picture
After the wire controller is started, the dynamic
startup picture is displayed, as shown in FIG. 1.
FIG. 1
Master Volume (VOLUME)
After start-up, enter into the main interface of the wire
controller——the master volume interface (VOLUME),
as shown in FIG. 2-1. Rotate the button to adjust
the master volume. Rotate clockwise to increase the
volume and anticlockwise to reduce the volume. The
adjusting range is 0 to 35. Short press the rotary knob
on the master volume interface to enter into the mute
interface, as shown in FIG. 2-2.
FIG. 2-1 FIG. 2-2
Main Sound Source (MAIN SOURCE）
Press on the rotary knob for 2 to 5 seconds on the
master volume interface to enter into the main sound
source interface (MAIN SOURCE), as shown in FIG. 3.
Rotate the button to select the main sound source: digital
(SPDIF), high level (Hi.L), Bluetooth (BT) and low level
(AUX). When the Bluetooth and the high level or low level
signal are connected simultaneously, the Bluetooth will
directly serve as the main sound source by default. After
no operation for about 5 seconds, it will automatically exit
this interface and return to the main interface of the wire
controller (master volume interface).
FIG. 3-1 FIG. 3-2
Auxiliary Sound Source (MIX SOURCE）
Short press the rotary knob on the main sound
source interface to enter into the auxiliary sound source
interface (MIX SOURCE), as shown in FIG. 4-1. Rotate
the button to select the auxiliary sound source: digital
(SPDIF), high level (Hi.L), Bluetooth (BT), low level
(AUX) and turn off (OFF). After no operation for about
5 seconds, it will automatically exit this interface and
return to the main interface of the wire controller (master
volume interface).
FIG. 4-1 FIG. 4-2
Bass Volume (SUB W)
Short press the rotary knob on the auxiliary sound
source interface to enter into the bass volume adjusting
interface (SUB W), as shown in FIG. 5. Rotate the
rotary knob of the wirecontroller to adjust the bass
volume of the machine. Rotate clockwise to increase
the bass volume and anticlockwise to reduce the
bass volume. The adjusting range is 0 to 15. After no
operation for about 5 seconds, it will automatically exit
this interface and return to the main interface of the wire
controller (master volume interface).
FIG. 5
Preset Sound Effect (PRESET)
Short press the rotary knob on the bass volume
interface to enter into the preset sound effect
interface(PRESET), as shown in FIG. 6-1. The number
behind PRESET represents the sound effect data called
by the machine currently.
FIG. 6-1
The required sound effect data can be selected by the
rotary knob. When the cursor moves to the corresponding
number, short press the rotary knob to call directly,
as shown in FIG. 6-2. After completing the call, it will
automatically exit this interface and return to the main
interface of the wire controller (master volume interface).
