6.4. Advanced Configuration (Via PC)

The device allows for advanced configuration settings by connecting it to a PC. These settings are typically managed via a configuration file on the device's storage.

• Recording Audio Level: Adjust the sensitivity of the microphone.
• Voice-Operated Threshold Level (VOX): Set the sound level at which recording automatically starts or pauses.
• Number of Channels: Configure mono or stereo recording (if supported).
• Sampling Rate: Adjust the audio sampling frequency for different quality levels.
• Bitrate: Select the recording bitrate (e.g., 192Kbps, 1024Kbps) to control file size and quality. Higher bitrates result in better quality but larger files.
• Automatic Maximum File Length: Set the maximum duration for a single recording file before a new file is automatically created. It is recommended to set this to the maximum (e.g., 255 minutes) to avoid short audio gaps between files.
• Internal Clock Synchronization: Synchronize the recorder's internal clock with your PC to ensure recorded files have accurate timestamps.

Refer to the specific configuration file (often a text file) found on the device when connected to a computer for detailed instructions on modifying these settings.
