Video conferencing using BYOD is supported Using a single USB port, BYOD devices such as a PC can be connected to AV peripherals such as monitors, speakers, microphones and cameras in the room, making it easy to convert a personal desktop into a professional conference room. -
Page 7: Supports Local Projection Screen
Use USB Type-B port and HDMI IN port for connection. 3.2. Supports local display BYOD devices can also extend the signal from a computer to a local display through a USB cable, making them extremely convenient super meeting terminals. The Conference box and computer can be connected in two ways to the display: Connect with USB Type-C port only. -
Page 8: Audio Processor Commonly Used Joint Conversion
When adjusting the gain, the clockwise direction is to increase the gain, and the counterclockwise direction is to reduce the gain. 3.4. Audio processor commonly used joint conversion 3.4.1. 3.5mm stereo audio cable (Small three core) to Phoenix terminal 3.5mm audio cable, commonly known as small three core. The 3.5mm audio plug is an unbalanced signal plug. -

the positive pole of another Phoenix terminal, and the peripheral ground is connected to the ground of the Phoenix terminal, and the negative hanging. See the following diagram: 3.4.2. RCA audio cable (Lotus head) to Phoenix terminal RCA audio cable, commonly known as Lotus Head. RCA audio cable is an unbalanced signal plug. -

4. Software 4.1. Software Download Device connection and configuration The default IP address for the processor is: 192.168.1.100. The subnet mask is: 255.255.255.0. Make sure both the PC and the processor are on the same network segment of the same local area network. If the PC is not on the same network segment as the processor, go to the PC network Settings to modify the network parameters. -
Page 12: Using The Software
4.2. Using the Software After opening the software, display the home screen: Clicking the button “Virtual Device” in the upper right corner of the main interface will automatically find all the processors on the network, and the user will connect to the specified processor as needed. After the connection is successful, the indicator is on, and the name of the connected device is displayed. -
Page 13: Audio Module Parameters
4.3. Audio Module Parameters 4.3.1. Input Source Phantom power supply: Feed the external capacitive microphone, enabled when connected to the microphone. Do not open without power supply, in case of damage to external equipment. Invert: The phase of the audio signal is reversed 180°. Mute: Mute the channel. -
Page 14: Limiter
In addition, in the main interface, each fader can control the gain of the corresponding channel. Clicking mute the channel. Right click on the fader to see the following menu Settings: Minimum Gain and Maximum Gain: Limit the maximum and minimum gain of this channel. -
Page 15: Ducker
The equalizer has the following control parameters: Frequency (Hz): The center frequency of the filter. Gain (dB): The value of the gain boost or attenuation in decibels at the center frequency position. OCT: Adjust the influence range of the corresponding node, 0.01 is the smallest influence range, 4 is the largest. -
Page 16: Auto Mixer
Threshold: The reference signal starts to decay above the threshold, and recovers below the threshold. Depth: The amount of maximum reduction by the Ducker signal. The left fader and mute button are the amount of attenuation, and the maximum attenuation is the depth control. - Page 17 The automatic mixing module has two sets of control parameters: • Main control parameters Gain: Controls auto mix main Output volume Slope: The slope controls the attenuation that affects lower levels. At higher slopes, low channel are attenuated more. When the slope is set to 2.0, it can achieve more ideal gain sharing and is the preferred value in use.

Page 18: Echo Cancellation
Note: Extreme priority differences between channel, such as 0 and 10, need to be used with extreme care in some settings. If a very high priority channel is picking up signals from the speaker, such as background noise, it is possible to mask a lower priority channel, even if the very high priority channel is not in use, the higher the slope of the problem is more serious. -
Page 19: Matrix
NLP processing: Set the linear processing effect of echo cancellation. The higher the setting value, the more obvious the echo cancellation effect is, but it will cause the local Input sound to eat words. The default value of 1 is sufficient. Local Input: The local microphone channel participating in the local Input. -
Page 20: High Pass & Low Pass Filter
4.3.8. High Pass & Low Pass Filter The purpose of the high pass and low pass filter is to filter out the frequency bands outside the selected range to achieve the desired performance. The following parameters can be adjusted: Low pass frequency: The cutoff frequency of the filter, below the set frequency can be passed. -
Page 21: Output
4.3.10. Output Invert: The phase of the audio signal is reversed by 180°. Mute: Set to mute/unmute. 4.3.11. Video Settings The video output configuration parameters are set uniformly to achieve the consistent display effect of HDMI1/2. The following parameters can be set: Manual/Automatic: In manual mode, you can click TYPE-C/HOST to switch interfaces. -
Page 22: Settings
Note: When the interface is switched, the control software may be disconnected from the device due to changes in the network and must be re-connected if necessary. The switch interface will switch the network card and sound card at the same time. EDID Settings: The following parameters are optional: Copy from Output 1, Copy from Output 2, 1920x1080@60Hz, 3840x2160@30Hz and 3840x2160@60Hz. -

Select the device and upgrade package to be upgraded and click “Updates”. Wait for the progress bar to complete the upgrade. 4.4. USB Sound Card Sound card Settings Connect the device to the computer host through the Type-B/Type-C data cable. After the connection, the sound card of the current device appears in the list of playback and recording sound cards in the computer sound panel, as shown in the figure. -

5. FAQ 5.1. Output no sound Check whether the processor RUN indicator light blinks slowly. Check whether the Input/output interface is correctly connected. Check whether the microphone input source and line input source have normal audio signals. 5.2. Output sound with current noise Whether the audio connection cable is made correctly. - Page 25 Follow us │ +1.408.213.6680 │ support@dvdo.com │ www.dvdo.com DVDO...
