Question
I was approached by a band that is looking for In Ear monitors for on stage performances. What are the pros and cons of wired v. wireless systems?
Answer
Thanks for your question.
In-Ear monitors are a sound system like any, and as you know they can be wired or wireless. For the front line folks, wireless is great, since it allows total freedom of movement. And since you are acoustically isolated from the system, you can absolutely go anywhere you want and be able to keep your monitor mix in tact! Many drummers, even those in large bands, use wired systems. They don't move around, so there is no advantage to go wireless. The downside of wireless is dealing with reception and interference issues.
These are pretty well known and there are lots of publications on the topic. Shure and Sennheiser are probably the best manufacturers of wireless systems and they offer lots of tutorials on the subject. The main thing is that in large cities, there's lots of "wireless traffic" and you have to be sure you are out of everyone else's way. In Japan, there are many cities (Tokyo among them) where it's illegal to use wireless systems in concerts! The airwaves are just too crammed. In the US and Europe, the big tour companies will do "RF sweeps" to find open frequencies for them to use, since they are often running a dozen or more channels with wireless microphones and guitar and bass lines ALONG WITH their in-ear monitors!
Wired systems are simply . . . Well, more simple and one less variable to deal with in the midst of getting your system up and checked. The downside to wired is, well, the wires!
Some bands prefer to deal with wires initially, to save money. Then when they can afford a good wireless system, they take that plunge!
I hope this information is helpful - best to you!
