5 Must-Know Tips About Wireless Audio
Over the years, I’ve had the pleasure of sitting down with product specialists from Lectrosonics, Rode, and Shure to discuss the latest in wireless technology and their products. I’ve also picked up some great tips for users no matter what wireless systems you use. Here we go.
1. Antenna Switching Diversity
As suggested by The Audio Blog, diversity technology allows your wireless system to constantly switch between two signals using the strongest signal at any given time. This happens in micro seconds without you even knowing allowing you to have the cleanest signal at all times. As a professional using wireless, you should always use diversity technology to make sure you avoid problems. Almost every company brands their diversity technology differently but as long as you see the word “diversity” you should be fine. The easiest way to spot a system with diversity technology is to look for the two antennas on the receiver (device on the right).
2. The Wireless Straw Trick
Wireless signals do not like water. Because our bodies are made mostly of water, it is never a good idea to let the antenna touch our skin. I learned this from a Lectrosonics rep and I remember it opened my eyes when he told me. Get this, by placing a straw over the antenna of the transmitter, the antenna will not touch the skin and still allow wireless signal to cut through like a knife. This is important to know because our goal with is to always maximize the signal.
3. Bending The Antenna Will Hurt Your Signal
￼Wireless systems rely on the full length of their antennas to give you the strongest signal. Did you know that bending the antenna is actually cutting down the power of the antenna? Antennas are made to certain lengths precisely for this reason. Always let the antenna extend to it’s full length without any bending to ensure the strongest and cleanest signal.
4. Polarity of Signal
Did you know it matters what angle your wireless transmitter and receiver are faced? Yep, the antennas should be parallel though wireless signal does bounce around rooms once transmitted. Keeping the antennas in parallel will always ensure a stronger and cleaner signal.
5. Scan Every Location
Every time you change locations with your wireless system, you should always re-scan the area. The reason to scan a room or area is to find the strongest signal available to avoid any interference. More expensive systems will usually go through a more detailed scanning process to choose from more frequencies.
