Volume Control
Each channel on the SR40 Mini Dual receiver has an independent volume knob. Adjust these knobs to control the output level of each microphone.
Indicator Lights
- RF OK (Green): This indicator illuminates when the receiver is successfully receiving a radio frequency (RF) signal from the corresponding transmitter.
- AF CLIP (Red): This indicator illuminates if the audio signal from the microphone is too strong, causing clipping or distortion. Reduce the microphone's input gain or the receiver's volume if this light frequently illuminates.
Maintenance
- Battery Replacement: The HT40 Mini transmitters offer an extended battery life of up to 30 hours on a single AA battery. Replace batteries when the microphone's indicator light dims or performance degrades. Always use fresh alkaline AA batteries.
- Cleaning: Use a soft, dry cloth to clean the exterior of the receiver and microphones. Do not use liquid cleaners or abrasive materials. For microphone grilles, a soft brush can be used to remove debris.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove batteries from the transmitters to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphone | Microphone or receiver not powered on; low/dead battery; incorrect cable connection; receiver volume too low. | Ensure both microphone and receiver are ON. Replace microphone battery. Check all cable connections. Increase receiver volume. |
| Distorted or clipped audio (AF CLIP light on) | Microphone input signal too strong. | Reduce the microphone's input gain (if adjustable) or lower the volume on the receiver. Ensure you are not speaking too loudly directly into the microphone. |
| Interference or dropouts | Obstructions between transmitter and receiver; too far from receiver; other wireless devices operating on similar frequencies. | Ensure clear line of sight between microphone and receiver. Reduce distance. Turn off other wireless devices that may cause interference. |
