4.1 Using the Lavalier Microphone or Built-in Mic
Each transmitter has a built-in omnidirectional microphone. For discreet placement or improved audio quality, you can connect the included 3.5mm TRS lavalier microphone to the transmitter's MIC input port.
- With Lavalier Mic: Plug the lavalier microphone into the 3.5mm MIC input on the transmitter. Clip the lavalier mic to clothing, approximately 6-8 inches from the speaker's mouth.
- Without Lavalier Mic (Built-in): Ensure no external microphone is plugged in. Clip the transmitter directly onto clothing, ensuring the built-in microphone faces the sound source.

Figure 5: Demonstrates the flexibility of the COMICA BoomX-D D2, allowing users to choose between the external lavalier microphone or the built-in microphone on the transmitter, depending on their recording needs.
4.2 Mono/Stereo Output Switching
The receiver allows you to switch between mono and stereo output modes. This is useful for post-production flexibility or specific recording scenarios.
- Modalità Mono: Combines audio from both transmitters into a single mono track.
- Modalità stereo: Records audio from each transmitter to separate left and right channels.
Refer to the receiver's display and control buttons to switch between these modes. The display will clearly indicate the selected mode.
