Headset microphone, ball, individually adjustable, beige,hard mini-jack plug  for Sennheiser pocket transmitter

4066 Omnidirectional Headband

•     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 headband 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 headband 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 headband Microphone to fail. The headband surface is matte gold plated and headband earhooks are covered with a silicon 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.

4066 is delivered with five foam windscreens.

This is the chosen headband for theaters on Broadway and West End.

Please note that the microphone comes with 1 High Boost and 1 Soft Boost Miniature Grid. It is available in three colors (black, beige, brown) and three sizes (small, normal, large).
