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 12 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:

Users can be customize the speaker type for each output channel, the specific
methods of operation:
The first step: Click on the right side of the "Reset Output Configuration" button in
the dialog box, select the "Clear" button, return to the main interface, all channels are
reset to "empty" (no connection to any speaker , there is no output of), as shown
below 3.3.4:
