5. Operating Instructions
5.1. Basic Recording
Once the system is set up and paired, you can begin recording. The audio from the transmitters will be wirelessly sent to the receiver, which then feeds into your recording device.
- Ensure your camera/recorder's audio input settings are correctly configured for an external microphone.
- Monitor audio levels on your recording device to prevent clipping or low volume.
5.2. Noise Cancellation
The BY-V4 transmitters feature an intelligent noise cancellation function to reduce ambient background noise.
- To activate noise cancellation, press the dedicated noise cancellation button on the transmitter. The indicator light may change color or pattern to confirm activation.
- Press the button again to deactivate the feature.
- Use this feature in noisy environments to enhance voice clarity.
