Wireless microphones are perfect for
singers, venues and schools as there are no wires to trip
Wireless microphones are available with
handheld microphones which contain their own
transmitter or headset or lapel microphones (right)
which connect by a short wire to a small belt-pack
You need one receiver per transmitter
- the receiver plugs into the mixing desk or speaker and
wirelessly receives the signal from the microphone
Which type of wireless microphone is
best - handheld or headset/lapel?
The general public often have problems using handheld
microphones because they hold them too far away from their
mouths, or wave them around when they are gesticulating. The
microphone volume is usually turned up too loudly to
compensate, and this can result in feedback. They are easy
to pass around though, in an audience situation.
Beltpacks can be used with headset
microphones or lapel microphones (sometimes called lavalier
or tie-clip microphones). Headset microphones are usually
better, in our opinion, as the microphone stays in a fixed
position next to the mouth, so it doesn't matter how much
the speaker moves around the volume stays constant. Unlike
tie clip or lapel microphones, which stay in the same place
as they speaker moves their head around, so the volume is
constantly going up and down.
Wireless microphones usually have a
range of 50 metres so the person singing or speaking can
be a fair distance away from the receiver. The signal will
even go through walls (but this will decrease the range). As
with any microphone, don't use it while standing in front of
the PA system speaker as you will get a squeal of feedback!
You can get single, dual or multiple
microphone systems: single have one microphone per
receiver, dual have two microphones plus two receivers which
are built into the same box. The benefit of the dual
receivers is that they can take up only channel on the
mixer if you take a mix from the back of the receiver. Dual
systems are much cheaper than two singles, and new six-way
systems are now also available - perfect for schools!
