Operating Instructions
1. Microphone Usage
Each transmitter has a built-in omni-directional microphone. For optimal sound capture, clip the transmitter to your collar. Alternatively, you can plug the included SR-M1 external lavalier microphone into the transmitter's MIC IN jack for more discreet placement.
2. Adjusting Mic Gain
Use the +/- buttons on the transmitter to adjust the microphone gain. The mic gain indicators will show the current level. Adjust the gain to prevent audio clipping or distortion.
3. Real-time Monitoring
The receiver features a 3.5mm headphone output jack, allowing you to monitor the audio in real-time. This is crucial for ensuring optimal sound levels and quality during recording.

4. Output Modes (Mono/Stereo)
The receiver supports selectable mono and stereo output modes. In mono mode, all four transmitters' audio will be mixed to a single output. In stereo mode, the audio from group A (transmitters 1 & 2) is output to the left channel, and group B (transmitters 3 & 4) to the right channel. This allows for greater flexibility in post-production.
5. Noise Reduction
The Blink500T4 incorporates an intelligent noise reduction chip to minimize ambient noise, ensuring clear vocals even in noisy environments.
