How to properly install the mic of the H9?
1️⃣Insert the boom mic completely into the jack. And make sure to align the boom mic with the tiny slot of the jack.
2️⃣Check if the mic can be muted by the switch button on the USB audio control box.
3️⃣After you plug the headset into the PC or laptop, please set it as the default input device in the system sound control panel and software audio settings; otherwise, the mic will not pick up the sound. And disable other mics manually.
4️⃣Check if the software using the mic allows the use of the default input device. Try turning on the Privacy Settings for apps that you want to use with your mic by following the steps below.
Click the “Windows” icon or press “Win” on your keyboard → Click "Settings" → In the pop-up Window, select the "Privacy & security" category → Scroll down and find the "Microphone" option → Make sure the "Microphone access" is enabled
What should I do if my boom mic isn't working?
Using the 3.5mm connection
Ensure your 3.5mm port supports both microphone and headphone audio. Otherwise, the microphone will not work. You need a Headphone Splitter to make the mic work if your computer has separate 3.5mm ports, or you can use the USB connection.
Using the USB connection
Ensure the mic is plugged firmly into the slot.
Using the H9 with a computer
Ensure you have set the mic as the input device of the PC and the software you need. Ensure you haven't muted the mic or turned the mic gain to minimum on the PC audio settings.
Using the H9 with the Mac
Ensure you have set the mic as the input device of the Mac and the software you need to use. Also, ensure you haven't muted the mic or turned the mic gain to minimum on the Mac audio settings.
