switch is switched to DC, the two high level input lines of FL+/FL- are defined.
When there is original car or other high level input, the machine will detect the
audio signal to start the machine.
Note: when do not use high level input (only RCA low level input), the toggle switch

2.the low level RCA output, CH1 to CH4 signal with the original car interface is the
same, but there is without power amplifier, the default output type of CH5 and
CH6 is null, while the default output type of CH7 and CH8 is ultra-low left and
ultra-low right, usually external bass amplifier, as bass strengthened. Of course,
users can configure their own initiative RCA low level output to complete more

when changing the channel editing, where there are only 3.2. 2 "4" zone (crossover
and equalization parameters) will vary depending on the channel and change the
parameter values.
3.3.3 Output volume, delay, type, mute and phase setting
In Figure 3.3.1, there are six output channels commonly used parameters are
displayed, the user can quickly adjust the parameters directly here. Of course,
users can also customize the horn type of each output channel.
Specifically adjusted as follows:
Figure 3.3.1
1．the output volume control, volume control for each channel independently and
the master volume, pushing the volume fader below each channel label can be
in OFF (off), - adjust between 59dB to 6dB; while on the right also has a total
volume of all output is adjustable, adjustment range is OFF (off), - between
-39dB to 6dB.
2．mute and phase adjustment, also under the label of each channel are phase and
mute both buttons select, and click on the button you can be between "positive
phase" and "inverted" Switch, click the mute button You can switch between
"open tone" and "off the sound." Figure 3.3.2 as follows:
