- Compact and Discreet Design: Easily concealed for on-camera or stage use.
3. Setup
Proper setup is crucial for optimal performance of your RE-92TX microphone.
3.1 Connecting the Microphone
- Ensure your wireless bodypack transmitter (e.g., Telex R100, RE-2, RE-1) is turned off.
- Align the TA4F connector of the RE-92TX microphone with the input jack on your bodypack transmitter.
- Push the connector firmly into the jack until it clicks into place, indicating a secure connection.
- To disconnect, gently pull back on the release collar of the TA4F connector and then pull the connector out of the jack. Do not pull directly on the cable.
3.2 Microphone Placement
The placement of the lavalier microphone significantly impacts sound quality.
- Optimal Position: For most applications, clip the microphone to clothing approximately 6-8 inches (15-20 cm) below the chin, centered on the chest. This position typically provides a balanced sound.
- Clothing Noise: Ensure the microphone is not rubbing against clothing, jewelry, or other objects, as this can cause unwanted noise. Use the included clip to secure the microphone firmly.
- Wind Noise: If operating outdoors or in windy conditions, consider using an additional foam windscreen (not included) to minimize wind noise.
- Proximity Effect: Be aware that placing the microphone too close to the mouth can result in an exaggerated bass response (proximity effect). Adjust placement to achieve desired tonal balance.
4. Operating
Once connected and placed, follow these guidelines for operating your RE-92TX microphone.
4.1 Gain Setting
The input gain on your wireless bodypack transmitter should be set correctly to prevent distortion and ensure a strong signal.
- Test Level: Speak into the microphone at your normal speaking volume.
- Adjust Gain: Adjust the gain control on your transmitter until the audio level indicator (if present) shows a strong signal without consistently peaking or clipping.
- Avoid Clipping: If the indicator frequently shows red or maximum levels, reduce the gain to prevent distortion.
4.2 Performance Tips
- Speak Clearly: Articulate your words clearly and maintain a consistent distance from the microphone for best results.
- Monitor Audio: If possible, monitor the audio output through headphones to catch any issues (e.g., clothing noise, low battery, interference) in real-time.
- Battery Life: Ensure your wireless transmitter has sufficient battery life for the duration of your use. Low battery can affect audio quality.
5. Maintenance
Proper care and maintenance will extend the life of your RE-92TX microphone.
5.1 Cleaning
- Microphone Capsule: Gently wipe the microphone capsule and grille with a soft, dry, lint-free cloth. Do not use liquid cleaners directly on the capsule.
- Cable: Wipe the cable with a damp cloth if necessary, then dry thoroughly. Avoid harsh chemicals.
- Windscreen: If a foam windscreen is used, it can typically be removed and gently hand-washed with mild soap and water, then air-dried completely before reattaching.
5.2 Storage and Handling
- Avoid Extreme Conditions: Do not expose the microphone to extreme temperatures, high humidity, or direct sunlight for extended periods.
- Protect from Impact: Handle the microphone carefully. Avoid dropping it or subjecting it to strong impacts.
- Cable Care: Do not sharply bend or crimp the cable. Coil it loosely when storing to prevent damage.
- Storage: Store the microphone in a clean, dry place, preferably in its original packaging or a protective case.
6. Troubleshooting
If you encounter issues with your RE-92TX microphone, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Microphone not connected properly Transmitter/receiver off Low/dead battery in transmitter Incorrect gain setting Faulty cable/microphone | Ensure TA4F connector is fully seated. Verify transmitter and receiver are powered on. Replace or recharge transmitter batteries. Increase gain on transmitter. Test with another microphone/cable if available. |
| Distorted sound | Gain set too high Microphone too close to sound source Damaged microphone element | Reduce gain on transmitter. Adjust microphone placement further from mouth. Contact support if distortion persists after adjusting gain and placement. |
| Excessive background noise/feedback | Improper microphone placement Room acoustics Gain too high | Ensure microphone is positioned correctly and not rubbing against clothing. Adjust room acoustics if possible. Reduce gain. |
| Intermittent sound | Loose connection Interference Low battery | Check all connections. Ensure clear line of sight between transmitter and receiver; check for other wireless devices. Replace or recharge transmitter batteries. |
