Use and operation steps

1 Web control and software download

The factory default IP address of the device is: 192.168.1.200 Subnet mask: 255.255.255.0. Please add the address

of the network segment to the PC first, so that the device can connect normally.

After the device is started, use a web browser to access the address "http://192.168.1.200/", as shown in the figure

below:

Control: Control channel parameters and enable and disable each processor

Scene: Quickly recall and save device scenes.

Download: The download link provides the download of the .Net framework PC software. The PC software supports

XP, Win7, and Win8 operating systems.

Before installing the PC software, please make sure that Microsoft .Net Framework 3.5 or above has been installed on

the PC.

When installing the software, some systems (such as WIN8) will pop up a prompt: "UserAccount Control Information",

please click the "OK" button to increase the software authority.

3 Menu bar and status bar

3.1 File

1) New: Create a new scene with factory configuration parameters that are available offline only.

2) open: Open the local saved scene, which is available offline only.

3) Save as: Save the current configuration as a file locally, only available offline.

4) Exit: Close the software.

5) language switching: simplified, traditional and English languages are supported.

3.2 Central Command

The central command generator can convert frequently used operations into a 16-character command code to

facilitate calls to external devices.

Each of these commands contains three different sets of parameters.Control command types: scene, input,

output, mix, parameter equalizer, graphic equalizer, expander, compressor, Automatic gain, delay, frequency divider,

limiter.

3.3 Device settings

Device settings include user settings, network settings, serial port settings, scene settings, camera tracking, and

GPIO.

1) User settings

a. The initial user name of the device is admin/password 123456, The administrator can add, delete, and modify all

user information; ordinary users can only modify personal information.

b. Modify user: First select the user to be modified in the user list, the user name and password edit box will display the

information of the currently selected user, enter new information, and click the "modify" button.

c. Delete user: select the row to be deleted in the user list and click the "Delete" button to delete the user.d、

D.Add user: Select the empty row in the left list, and enter the new user's information in the user name and password

edit box on the right (should be empty), and click the "Add" button to add a new user.

2) Network settings

View and modify the network address information of the device, enter the IP address, subnet mask, and gateway in the

corresponding position, and click theApply button to complete the modification

3) Serial port settings

View and modify the serial port information of the current device. Click "Apply" button to modify the serial port

information of the current device after setting;If you want to return to the default value, directly click the "All Reset"

button, and the items cannot be empty when setting.

4) Scene settings

a. Modify name: modify the selected scene name.

b. Upload scene: upload the scene on the PC side and overwrite the selected scene.

c. Save scene: Save the current running parameters to the selected scene.

d. Save as: Save the currently running parameters to the PC in a scene.

e. Load scene: enable the currently selected scene, usually used for scene change.

f. Restore factory settings: restore all scene configurations to the default configuration.

This device supports two ways to save scenes offline and online. Offline save is to save the set scene on the PC,

which is convenient for subsequent recall and scene copying between different devices. Saving a scene online is to

save the scene directly to the device, which can be recalled directly after turning on the device next time

.4 DSP module

4.1 Input Setting

The input signal can be an analog signal or a test signal generated inside the device. If it is a network version with

Dante, it can also be a network digital signal;

The analog signal can be selected by adjusting the sensitivity to adjust the input; from -60~0, every 3dB;

Mute: the channel is muted when selected;
