DPA 4066B headset microphone

The DPA 4066B omnidirectional headset (headband) microphone is industry-standard in theatres and conference venues. Very discreet yet surprisingly rugged the DPA 4066B offers excellent feedback rejection and exceptional sound quality. We usually supply the DPA 4066B for hire with adapters for our Sennheiser Evolution G3 or Shure UHF-R wireless systems. Please ask about other options if required.

The DPA 4066B 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 DPA 4066B 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.

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