• use it for both left and
right mounting
• resistant to humidity
• works with all professional wireless systems
• available in three colors and three sizes
The 4066 is a flexible miniature microphone solution that features
very easy and fast adjustment. The headset construction is unique
in design, offering both left and right mounting and color change.
It is also possible to use the MMB4066 Miniature Microphone Boom,
Omnidirectional, separately, in applications where the headset is
not needed.
The 4066 offers a clean and transparent sound quality with lots of
headroom.
Attention has been paid to the humidity problems that often occur
in theatrical applications. A double vent protection system, a drop
stopper on the microphone boom, together with water resistant
materials inside the microphone, makes it more than difficult for
the humidity to cause the microphone to fail. The headset surface
is matte gold plated and the earhooks are covered with a silicone
hose.
The sensitivity is 6 mV/Pa to match the level of the human voice to
the general input sensitivity of most wireless transmitters. If
powered correctly the microphone will be able to handle sound
pressure levels up to 144 dB SPL before clipping occurs.
A wide range of connection adapters makes it possible to use the
4066 with most of the professional wireless systems available plus
48 V phantom XLR connection.
The chosen headset mic for theaters on Broadway and West End, 4066
is available in three colors (black, beige, brown) and three sizes
(small, medium, large).
