4. 操作手順
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.
- モノモード： 両方の送信機からのオーディオを 1 つのモノラル トラックに結合します。
- ステレオモード： 各送信機からの音声を左チャンネルと右チャンネルに別々に録音します。
Refer to the receiver's display and control buttons to switch between these modes. The display will clearly indicate the selected mode.
