Before using a wireless microphone, it's essential to ensure everything is set up correctly to avoid any issues during the performance. The operator should carefully inspect the wireless microphone system, make sure all components are properly connected, and position the antenna correctly to maintain a stable signal. These steps are crucial to prevent sound dropouts or complete loss of audio during the event.
Here are some key points to check before starting:
- Ensure the battery compartment is securely closed and that the batteries have sufficient power. Weak batteries can cause unexpected shutdowns during critical moments.
- Turn on the receiver first and check the RF meter. Make sure there is no interference on the selected channel before powering on the transmitter.
- Verify that the mute switch on the microphone is off so that the transmitter is always active and ready for use.
- Attach the waist-mounted transmitter to your belt, keeping the antenna hanging freely to avoid bending or sagging. Avoid direct contact with skin, especially if the performer is likely to sweat, as this can affect the device's performance.
- Avoid touching the transmitter with metal objects like keys or belt buckles, as they can cause frequency drift and signal instability.
- Keep receivers separate to reduce the risk of internal interference between units.
During the performance, continuously monitor the signal strength indicator to detect any potential interference from other wireless devices. If multiple microphones are being used, avoid placing them together or near the receiving antenna, as this can create intermodulation interference and degrade sound quality.
If you notice noise or distortion, it could be due to a misaligned microphone capsule, high sensitivity settings, or an interfering frequency. Common sources of interference include mobile phones, walkie-talkies, and cordless phones. In such cases, try switching to a different frequency. When changing frequencies, always adjust the receiver first to find a clear channel, then update the transmitter accordingly.
Poor reception can also occur due to physical obstructions in the venue, such as pillars, metal structures, or glass surfaces that reflect signals. Additionally, if the sound control room is far away or blocked by walls, it may affect signal strength. To improve reception, consider using a diversity system (one microphone with two antennas), which offers better coverage. You can also reposition the antenna or extend its length if needed. As a temporary fix, use a long video cable (10–15 meters) to connect the receiver’s antenna to a more favorable location where the signal is stronger.
When replacing batteries during a performance, always turn off the microphone first, replace the batteries, and then power it back on to avoid signal disruption.
