# Any good wireless mike systems at reasonable cost?

Hi All,

This one is more for our church. I am just looking around for possible
alternatives here. Does anybody know a good wireless microphone system
that works digitally, maybe in WLAN fashion? It should be in the $2-3k range for a setup with two lapel mikes and two handhelds. The reason I ask is that many analog versions are not great designs at all. They produce a loud pop whenever someone turns off their mike, sometimes even when activating the mute switch. Poor squelch design I'd guess. Others produce a tremendous noise when someone turns a light switch. Battery lifetime for a mike should be at least five hours, better six or seven. So if you have a great system at your church or somewhere else, could you peek into the audio room and post what brand and model it is?

At a former employer of mine we always sold Sennheiser to churches
because we found out their wireless mics worked best compared to other
brands. Their most recent models also have a reasonable price. The
battery life shouldn't be an issue for todays high capacity
rechargable batteries, but the trick is to charge the batteries
properly in order to keep them 'fit'. Finding a good charger (which at
least discharges the batteries before charging them) can be quite
difficult.

Hi Nico,

rechargable batteries, but the trick is to charge the batteries

difficult.
The larger system we have is a Sennheiser but it pops loudly when
turning off mikes. Maybe the newer ones are better but we'd make a
purchase conditional upon that. EMI is pretty good on that one. Battery
life, well, isn't so great. It needs 9V batteries and even with the
largest cells (250mAh) it barely gets to five hours. That's tight for a
Sunday morning with 1st service, immediately followed by bible class and
then 2nd service. There isn't much time to change batteries.

Also, these use UHF channels as secondary users. Works most of the time
but it can become a problem every time some station is allocated a new
digital channel. Best would be a wideband spread spectrum solution,
preferably at 5GHz where it isn't so crowded yet. It can't be so
difficult technically since we can by wireless phones for 5GHz and they
sell around \$150 for the base station including two additional handsets

A really simple fix for battery life would be to design a "pop free" RF
turn off and then switch off the whole mike instead of just muting it.
In mute mode it still drains the battery. Can't be difficult to design.

We did find an excellent charger. It is the Ansmann "Energy 16" which
has an elaborate uC scheme to prep, charge and trickle each individual
battery. So we've got two of those now. This was the only one for our
specs I could find after a pretty exhaustive search.

The "best" solution is simply to cut the bible class and the 2nd
service. Its all made up fantasy so nothing will be lost

It is not fantasy at all. Many, many times archaeologists have said the
same, for example claiming that the city of Niniveh really never
existed. Until they found its remnants way below the soil, at exactly
the spot where the bible said it was...

Of course it is. Religion is entirely made up. The stupid, peasants, of
a few 1000 years ago, who knew no better, simply said, well, a man, who
knows, everything, can do anything, and is everywhere at once, made
everything. Like, get real dude.

This has nothing to do with my point. That is not religion, that is
history.

So what, even if true. For starters, is amazingly how "round about 100
miles" ends up as "exactly".
