Microphone Choices
M140 - A cardioid (directional) microphone for lavaliere
(“lapel”) use. Due to the directional pickup pattern,
this model will generally provide more gain (loudness)
before feedback than the M119 omni-directional model.
The M140 has a “brighter” sound than the M119 (the
treble is boosted). This crisper sound normally im­
proves the clarity that is sometimes lost with lavaliere
type microphones. The M140 is subject to wind noise
and generally works best indoors, however it is supplied
with a foam windscreen which helps to prevent noise
caused by wind.
HM162 - A “over the ears” noise cancelling microphone
that uses a dual-element design to minimize feedback
when the microphone is close to the speaker.
Other brands of microphones may be used, provided
they are the correct type, with an appropriate connec­
tor. Consult the factory or your dealer if you are not
sure. A mis-matched microphone will generally cause
background noise (hiss) or feedback problems, or may
not work at all.
