DPA 4066-F

4066-F description:

The DPA 4066-F Adjustable Miniature Microphone Headband, Beige. Highly regarded by engineers and the chosen headband for theaters on Broadway and the West End.

The DPA 4066-F is a flexible miniature microphone solution, that features very easy and fast adjustment possibilities. The headband construction is unique in design, because it gives the user the choice between left and/or right mounting and colour 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 matgold 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. The DPA 4066 is delivered with 5 foam windscreens.
