3.2.2 Mode Selection
- [Tablet Mode]: Device speaker on, microphone off, microphone volume not adjustable. Use this mode for daily activities like watching videos or listening to music without a microphone.
- [Live Mode]: Device speaker off, microphone on, microphone volume adjustable. The speaker is turned off to prevent audio feedback and howling in the live stream. Use this mode during streaming.
3.2.3 Sound Settings

- [Reverb]: Adds reverb effect to the microphone. Long-press + to enhance, long-press − to reduce.
3.2.4 Microphone Settings
- [Built-in Mic]: Built-in microphone. Must be in Live Mode — enable the switch first, then adjust the volume.
- [External Mic]: External mic switch, corresponding to the Dynamic Mic input. See the red arrow in the diagram.
- [Lapel Mic]: Lapel mic switch, corresponding to the LINE IN 2 input. See the green arrow in the diagram.

3.3 Audio Testing
3.3.1 Built-in Mic Test
To test the built-in microphone: connect wired headphones to monitor directly. If no headphones are available, follow these steps: switch to Live Mode, set volume to maximum, enable the built-in mic, and set mic volume to max. Start video recording and speak into the camera area for ~10 seconds, then stop. Switch to Tablet Mode, open the video folder, play the recorded video, and increase the volume. If audio is present, the built-in mic is working normally.
3.3.2 3.5mm/6.5mm Mic Test
To test a 3.5mm or 6.5mm microphone: follow the same steps as the built-in mic test, but make sure to enable the correct audio switch (refer to Section 3.2.4 — Microphone Settings).
3.3.3 Type-C Lapel Mic Test
To test a Type-C lapel mic: select the Type-C lapel mic sound card. Switch to Live Mode. When using the Type-C lapel mic, audio is handled by the lapel mic — the built-in mic, external mic, and lapel mic switches can be turned off. Set volume to max, start recording, speak into the lapel mic for ~10 seconds, then stop. Switch to G5 USB Sound Card + Tablet Mode, open the video folder, play the recording, and increase the volume.
