4. Setup and Installation
Follow these steps to properly set up your J K Pro MIC-J S90 microphone:

- Position the Boom Arm: Adjust the boom arm so that the microphone capsule is positioned approximately 1-2 inches from the corner of your mouth. This optimal distance helps capture clear audio while minimizing breath sounds.
- Secure the Cable: Route the microphone cable discreetly down your back and secure it to your clothing using the included tie-clip, if desired, to prevent snagging or movement.
- Connect to Transmitter: Plug the 4-Pin Hirose connector into the corresponding input port on your Audio-Technica wireless bodypack transmitter. Ensure a secure connection.

5. Operating Instructions
Once the microphone is properly set up and connected to your wireless transmitter, ensure the transmitter is powered on and correctly paired with its receiver. Adjust the gain levels on your transmitter and mixing console to achieve optimal audio levels without distortion. The omnidirectional polar pattern captures sound equally from all directions, providing consistent audio even with head movement.
6. Maintenance
- Cleaning: Regularly wipe the microphone and cable with a soft, dry cloth. For hygienic purposes, replace foam windscreens periodically, especially when used by multiple individuals.
- Storage: When not in use, gently coil the cable and store the microphone in a protective case to prevent damage to the delicate boom arm and connector.
- Handling: Avoid excessive bending or pulling on the boom arm or cable, as this can damage internal wiring.
7. Troubleshooting
- No Sound:
- Ensure the microphone is securely connected to the transmitter.
- Verify the transmitter is powered on and has fresh batteries.
- Check that the wireless system (transmitter and receiver) is properly paired and operating on the correct frequency.
- Confirm audio levels (gain) are set appropriately on both the transmitter and the mixing console.
- Distorted Sound:
- Reduce the gain level on the transmitter or mixing console if the sound is clipping.
- Ensure the microphone capsule is not too close to the mouth, which can cause plosives or over-modulation.
- Check for interference from other wireless devices.
- Intermittent Sound:
- Check all cable connections for looseness.
- Ensure the wireless system is within range and free from obstructions.
- Verify battery levels in the transmitter.
