3. Operating Instructions

3.1. Power On/Off

The transmitters and receiver automatically power on when removed from the charging case and power off when placed back into the case.

3.2. Recording Modes

The Lark 150 offers three recording modes, selectable on the receiver:

• Mono Mode: Combines both transmitter audio signals into a single mono track. Ideal for single-person recordings or when a combined audio track is desired.
• Stereo Mode: Records each transmitter's audio signal to a separate channel (left and right) for individual control in post-production. Suitable for two-person interviews or distinct audio sources.
• Safe Track Mode: Records the main audio signal on one channel and a secondary backup track on the other channel at a lower volume (typically -6dB). This helps prevent audio clipping or distortion in case the main track's volume is too high.

3.3. Mute Function

Both the transmitters (TX) and the receiver (RX) are equipped with mute buttons. This allows either the speaker or the operator to pause audio recording as needed, providing flexible control during a shoot.

3.4. Real-time Audio Monitoring

The receiver features a 3.5mm headphone jack for real-time audio monitoring. Connect headphones to this jack to listen to the audio being recorded and adjust settings as necessary.

3.5. Intelligent Noise Cancellation (DSP)

The Lark 150 incorporates DSP (Digital Signal Processing) technology for intelligent noise reduction. This function helps filter out low-frequency environmental noise, ensuring clearer and more focused audio recordings. This feature can be toggled on or off via the receiver settings.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Lark 150 system.

• Cleaning: Use a soft, dry cloth to clean the transmitters, receiver, and charging case. Avoid using liquid cleaners or solvents.
• Storage: Store the system in its charging case when not in use to protect it from dust and physical damage. Keep it in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For optimal battery life, fully charge the system before extended storage and recharge it periodically (e.g., every three months) if not used for a long time.
• Microphone Care: Handle the lavalier microphones gently. Use the furry windshields to protect them from wind noise and moisture when recording outdoors.

5. Troubleshooting

If you encounter issues with your Lark 150 system, refer to the following troubleshooting tips:

• No Sound Output:
  • Ensure both transmitters and receiver are powered on and paired.
  • Check all cable connections between the receiver and your recording device.
  • Verify that the transmitters and receiver are not muted.
  • Confirm the recording device's audio input is correctly selected and its volume is up.
  • Check battery levels of all units.
• Poor Audio Quality (Static, Dropouts, Low Volume):
  • Ensure transmitters and receiver are within the optimal operating range (up to 100m line of sight).
  • Minimize obstructions between TX and RX.
  • Check for strong 2.4GHz interference from other devices (Wi-Fi routers, other wireless systems).
  • Adjust the input gain on the receiver and/or your recording device.
  • Ensure the lavalier microphone is securely connected to the transmitter and positioned correctly.
  • Activate the Intelligent Noise Cancellation feature if background noise is an issue.
• Units Not Pairing:
  • Place transmitters and receiver back into the charging case, then remove them to trigger automatic pairing.
