Cut Down Interference in Wireless Mics
What is interference?
Interference is that annoying hum that you hear when you play back your audio.
Interference is annoying and often frustrating, especially when you don't know it is there until you play back your filmed hunt. Efforts to correct interference problems are also often complicated by the fact that there are several kinds of interference and each requires a different approach and a different solution. Sometimes a "quick fix" will work, more often it does not. Unless the problem is very simple, the only really productive approach is an orderly and systematic one that first finds the cause of the specific problem, then applies appropriate corrective action.
Here are some quick fixes:
• Check you batteries - weak batteries can cause interference.
• Make an interference loop with the cord by the lavalier mic.
• Turn your cell phone off or your data off. The transmission of data (even in the background) can cause interference.
• Don't film around low frequency equipment such as a refrigerator or telephone polls.
• Make sure it is not the receiver cable. Always store your cables properly.
ALWAYS USE HEADPHONES TO MONITOR THE AUDIO RECORDING TO MAKE SURE YOU CAN DETECT INTERFERENCE BEFORE IT RUINS YOUR VIDE0.
