DGM20 Software User Guide
The DGM20 software is the Windows desktop app for the DGM20 USB microphone. It gives you the settings that are not available on the microphone itself: firmware updates, real-time monitoring, noise cancelling, sound enhancement, and a factory reset.
You do not need the software for everyday use. Once the microphone is plugged in, it works as a standard USB microphone, so calls, streaming, and recording work without it. Install the software when you want to change the settings on this page.
System requirement: Windows 10 or later. The software is available for Windows only.
Download and Installation
Figure 1 — Download entry for the DGM20 software.
-
Open the page and download the DGM20 installer for Windows.
-
Run the installer and follow the on-screen prompts.
-
Connect the microphone to your computer with the original USB cable. Plug it directly into a USB port on the computer rather than a hub or docking station.
-
Open the software. If Windows shows a permission prompt for the microphone, allow it — without it, the software cannot read the device.
-
The software detects the microphone automatically. When it does, the connection status shows Linked.

1. Connection Status
| Status | Meaning |
|---|---|
| Linked | The microphone is connected and recognized. All settings are available. |
| No Link | The microphone is not detected. The controls are greyed out or unavailable. |
If the microphone is plugged in but the status still shows No Link, work through the checks below in order:
-
Use the original USB cable, and connect the microphone directly to the computer instead of a hub or docking station.
-
Try another USB port on the computer. On a desktop, use a port on the back panel.
-
Confirm that Windows sees the microphone: open Settings → System → Sound → Input. If the microphone is not listed there either, the problem is the cable, the port, or the device — not the software.
-
Close other software that may be using the microphone, then reopen the DGM20 software.
-
Restart the software. If it still shows No Link, restart the computer and try again.
-
If none of the above helps, reinstall the software and allow any permission prompt during the first launch.
2. Language Selection
The interface is bilingual and ships with both Chinese and English.
-
Click the language option and choose Chinese or English.
-
The change takes effect immediately — no restart is needed.
-
The language setting applies to the software interface only. It does not change the audio, the firmware, or any saved settings.
3. Microphone Firmware Update
Firmware is the software built into the microphone. Updating it can fix known issues and improve stability.
Every microphone is shipped with the current firmware installed, so a manual update is usually not needed. Only update when technical support asks you to, or when the software reports that a newer version is available.
-
Connect the microphone directly to the computer and confirm the status shows Linked.
-
Open the firmware update option and check the current version.
-
If a newer version is available, start the update.
-
Wait until it finishes. It may take a few minutes. Do not unplug the microphone, close the software, or put the computer to sleep during the update.
-
The microphone reconnects automatically when the update is complete.
Note: If the update is interrupted, reconnect the microphone and run it again. Do not unplug the device while the progress bar is still moving.
4. Monitor (Real-Time Monitoring)
Monitor plays your own voice back through the microphone's headphone jack while you speak.
| Scenario | Monitor | Why |
|---|---|---|
| Podcasting, interviews, voice-over | On | You hear your level and delivery as you record, so you can catch a quiet take or a wrong distance immediately. |
| Gaming, voice chat, online meetings | Off | You do not need to hear yourself, and monitoring in a call often causes echo or feedback for the other side. |
| Recording with speakers instead of headphones | Off | The microphone will pick up the speakers and create a howling loop. |
Because monitoring runs on the microphone hardware rather than through the computer, you hear yourself with almost no delay. If your headphones are connected to the computer instead of the microphone, the voice you hear goes through the computer's audio path and may be delayed — plug the headphones into the microphone to avoid this.
Note: Use headphones, not speakers, when monitoring is on. Monitoring through speakers in the same room causes feedback.
5. Factory Reset
Factory Reset restores the microphone and all of its settings to the factory default values.
-
Use it when the microphone behaves abnormally, settings no longer respond, or you have changed several options and want a clean starting point.
-
A factory reset erases all custom settings, including the noise cancelling level and the monitoring state. Even so, it does not erase recordings or files on your computer.
-
After the reset, the microphone reconnects. If it does not, unplug it and plug it back in.
6. Noise Cancelling
Noise cancelling reduces steady background noise — fans, air conditioning, keyboards, traffic — before the audio reaches your computer. It does not remove voices in the same room, and it cannot replace a quiet room or a microphone placed close to your mouth.
Turn it on, then drag the slider to set the strength: the higher the value, the stronger the reduction.
Figure 2 — Adjusting the noise cancelling strength.
Starting values
| Environment | Start at |
|---|---|
| Light background noise (keyboard, air conditioning) | 52 |
| Moderate background noise (fan, voices in the next room) | 64 |
| Heavy background noise (street noise, public spaces) | 82 |
How to tune it
-
Turn noise cancelling on and set the slider to the value from the table above.
-
Speak at your normal volume and distance, and listen to the result in your headphones or in a test recording.
-
If background noise is still audible, raise the value a little. If your voice starts to sound thin, hollow, or robotic, lower it — a strong setting removes parts of the voice along with the noise.
-
For music, singing, or anything where the natural tone of the voice matters, turn noise cancelling off.
Note: These values are starting points, not rules. The best setting depends on your room, your distance from the microphone, and how loud you speak.
7. Sound Enhancement
Sound Enhancement boosts the level of your voice. Turn it on when people tell you that you sound quiet, or when you speak softly and do not want to move closer to the microphone.
-
It is a single switch — there is nothing to adjust.
-
When it is on, the microphone raises the overall level of your voice before the audio reaches the computer, so the result is louder but keeps its natural tone.
-
It does not fix a poor signal. If your input is already too high and the audio is clipping, boosting it further only makes the distortion worse.
When to turn it on
| Situation | Sound Enhancement |
|---|---|
| You speak softly, and listeners ask you to speak up | On |
| The microphone is set up further away than usual, such as on a stand across the desk | On |
| Calls or streams sound quiet on the other end even with normal gain | On |
| You are shouting, singing, or recording an instrument close to the microphone | Off |
| The level is already near maximum, or the audio is distorted | Off — lower the gain first |
Keep it in proportion with gain
Sound Enhancement and the microphone's gain both make you louder, and they add up. A practical approach:
-
Set the gain to a normal position and speak at your usual volume.
-
If people still say you are quiet, turn Sound Enhancement on instead of pushing the gain higher.
-
If the audio becomes harsh or distorted, turn it off and lower the gain. Distortion is not a sign that the boost is working.
Note: Sound Enhancement changes the level of the voice the microphone sends to the computer. If the volume is still low after switching it on, check the input level in Windows: Settings → System → Sound → Input → Device properties.
Troubleshooting
The software shows No Link even though the microphone is connected.
Follow the six checks in 1. Connection Status. In most cases the cause is a charge-only USB cable, a hub, or the microphone being used by another program.
The software detects the microphone, but the app I am using receives no audio.
This is usually an input selection issue rather than a software issue. Open the audio settings of that app and select the DGM20 as the microphone. Also check Settings → System → Sound → Input in Windows and make sure the DGM20 is set as the default input device.
Monitoring is on, but I hear nothing in my headphones.
-
Confirm that the headphones are plugged into the microphone, not the computer.
-
Check the headphone volume on the microphone itself — the software setting does not replace it.
-
Try another pair of headphones to rule out a faulty cable or plug.
I hear an echo or a howling sound.
Monitoring is picking up your speakers. Use headphones, or turn monitoring off. If the echo only appears in a call, the other participants are hearing their own audio back — turn monitoring off for calls.
Noise cancelling makes my voice sound unnatural.
Lower the slider. Strong noise reduction also removes part of the voice, which is what makes it sound thin or metallic. 52–60 is enough for most rooms.
Sound Enhancement is on, but my voice is still quiet.
The boost applies to the level the microphone sends to the computer, so check the level further down the chain:
-
In Windows, open Settings → System → Sound → Input → Device properties and check the input volume.
-
In the app you are using, check its own microphone volume or automatic gain control setting. Some apps lower the input on their own, which cancels out the boost.
-
In recording software, check the track's recording level before you raise anything on the microphone.
The audio sounds distorted or harsh with Sound Enhancement on.
Turn it off and lower the gain on the microphone. The microphone is being driven too hard; no amount of enhancement will make that sound better.
The software does not open, or the window stays blank.
Close the software completely and open it again. If that does not help, reinstall it and allow any permission prompt during the first launch. Make sure your computer is running Windows 10 or later, as noted at the top of this page.
