There is a small hole beside the mesh, marked with R, which is the reset key. Long press for more than 5 seconds is effective. After reset, the device will return to the exit setting, and the password will return to the default password.

The horizontal is the output and the vertical is the input.

RS485 corresponding interface on the back panel of the processor is -, +; Connect the corresponding interface of central control host or control terminal respectively.

RS232 corresponding interface on the back panel of the processor: G, Rx, TX; respectively indicating: grounding, receiving command, sending command.

The default IP address of the device is 192.168.1.200, so when setting the network segment, you can set the 192.168.1.xxx network segment.

The scene Settings of the main control device and PC terminal are eight scenes, including scene 1, scene 2, scene 3 and..., scene 8; In the scene setting of device Settings, you can perform the following actions for the scene: Load scene: load the selected scene in the list into the currently connected device; Save as: save the changes made in the current software to the local computer;Save scenario: save the changes made in the current software to the selected item in the list; Upload scene: upload the scene file from the local computer to the processor and load it as the current scene; Modify the name: edit the name in the scene list; Restore default scenario: restore configuration parameters to scenario 1.

1）Check whether the input-output interface is connected correctly. The upper row of the back panel is the input, and the lower row is the output. Every three pins from left to right represent a channel. 2）Check whether the channel corresponding to the mixer is open. 3）Check whether there is sound in the input source, and use line input test. 4）Check the parameters of the front voltage limit and the back voltage limit. If the level or ratio is too high or the gain is too small, the sound will be small or even inaudible. 5）Check the mute parameters and corresponding level values of the input and output channels. 6）Check whether the frequency parameter setting of the frequency divider is correct. In this version, it is band-pass, and in the band-stop state, all sounds in the frequency band will be shielded.

First, we should check whether there is a problem with our network cable (ordinary network cable), and then check whether the device and PC are in the same network segment. The initial IP of our device is 192.168.1.200, so we first consider setting the network segment of 192.168.1.*, but please do not set it to the same IP address of the device.After setting up again open PC operating software for device search and connection can be.

Please contact our customer service for firmware upgrade package.

The web page control mode has certain requirements for the browser, it is recommended to use A non-IE core browser access.

First, check whether the device and PC are connected successfully. Second, check whether the device and PC are in the same network segment, but please do not set it to the same IP address as the device.In addition, the browser cache may also cause the page to be unable to display. Just clean up the cache.

1) the output sound quality is closely related to the input level and output level. Normally, the input level is less than -20db and the output level is less than -15db. At this point, adjusting other parameters will have a better effect. 2) Check whether the configuration of other parameters, such as EQ parameters and frequency divider are reasonable. 3) The signal generator will produce some noise, check whether it is turned off. 4) The noise door can filter the white noise when there is no human voice, open the noise door and then detect the sound quality. 5) The echo will be generated when the mic is input, which can improve the sound quality by turning on feedback elimination.

Our DSP processor do not provide the installation CD, the software installation package has been integrated into the processor, you can access the IP address of the processor through the web browser (default address: http://192.168.1.200/) to download the installation package.

1）Read the instructions carefully and pay special attention to safety. 2） Connect PC end, device, audio input and output device according to the instructions of the back panel. Firstly, PC end and device can be connected via LAN network (otherwise, please pay attention to the location of the interface); Next, connect the signal input device (microphone, line input device, etc.), The signal input interface and the signal output interface are located on the right side of the back panel. 3）Plug in the power and test the device: select the device list in the local device from the menu of the system, double-click the IP address corresponding to the device in the list, and then enter the user name and password in the pop-up dialog box to complete the login. 4）If the login is successful, you can manipulate all other functions

No light: First, check whether the power connection and device power supply are normal; Second, check whether the power switch on the rear panel of the device is on. Blinking: Unplug all GPIO connection cables and reboot the device. If the problem is not solved, please contact the distributor or manufacturer.

After 18 seconds of power-on, the system is working normally and the system light of the device should be flashing once per second. Does not light up, often light up, or blinks rapidly: First, system error, contact the after-sales service to upgrade the software version; Second, long press the reset button (R hole on the rear panel of the device) for more than 6 seconds, the device will restore the factory settings and restart automatically. If the problem is not solved, please contact the distributor or manufacturer.

Network connection failure is usually caused by different network segments of the device. If the LAN and the processor network segments are different, you can connect the processor directly via PC, login to the device configuration interface, change the processor network segment to be the same as the LAN and then access the LAN. (Note: If the LAN is automatically obtaining IP, please use 0.0.0.0 for the processor IP).

Please check whether the processor is well grounded, which usually requires the grounding screw on the left side of the rear panel of the chassis to be connected to the metal enclosure such as the cabinet through a metal wire. If the problem still exists, please check the wiring of the input devices. If the input devices are unbalanced (two wires), please connect the "+" and "G" of the input connector of the processor.

After the system is set up, there is noise troubleshooting: First, unplug the device output audio cable, there is noise, please check the causes of the back stage equipment; Second, restore the output wiring, mute the corresponding output channel, there is noise, if unbalanced connection, try to shorten the connecting line, to avoid the introduction of interference, if balanced connection, try to disconnect the ground wire; Third, cancel the corresponding channel mute, unplug the device input audio cable, there is noise, long press the reset button (R hole on the rear panel of the device) for more than 6 seconds, the device will restore the factory settings and restart automatically;Fourth, restore the input wiring, turn off the audio source, there is noise, check the input connection, refer to the second point of the processing; Fifth, check the audio source is there is noise. If the problem is not solved, please contact the distributor or manufacturer.

First, check whether the connection is normal, the central control host TX connected to the device's RX, the central control host RX connected to the device's TX, the central control host and the device's ground interconnect; Second, check the software configuration of the device interface items: baud rate, start bit, stop bit, etc. Settings are the same as the interface configuration of the central control host. If the problem is not solved, please contact the distributor or manufacturer.

The device only supports FAT32 format U disk, only supports MP3 or WAV format audio files, audio files need to be stored in the root directory; ensure that the U disk is writable, the device needs to create a playlist. U disk has more than one partition only recognizes the first partition.
