DPA 4066是一款灵活且易于调节的全指向头戴话筒，能提供纯净的声音和充足的动态余量。多年以来，DPA 4066一直是广播从业人员、百老汇和伦敦西区剧院的。即使在恶劣和潮湿的环境中，它仍然非常可靠，保证音质恒定一致。话筒可以佩戴在左侧或右侧脸颊。DPA 4066 头戴式迷你小话筒具有与4061相同的话筒头，不同的是它们可以方便的佩戴在脸颊侧面。4066还可以从镀金支架上拆卸下来，与4060系列的安装附件搭配使用。在实际应用中表现了出色的声音透明度和自然性，同时也有出众的防潮能力和机械稳定性。
4066是一个灵活的微型话筒解决方案，其特点是具有非常容易使用和便捷的调节。特有的头戴式结构设计，因为它可以让使用者选择左右安装和改变色彩。它也能够使用MMB4066微型话筒，全指向性的，分离地，应用在不需要头戴话筒的地方。
Miniature Microphone Solution
The 4066F is a flexible miniature microphone solution, that features very easy and fast adjustment possibilities and a beige color. 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 separately, in applications where the headband is not needed.
The 4066 offers a clean and transparent sound quality with lots of headroom. It uses a prepolarized omnidirectional cartridge element with a 5.4mm vertical diaphragm. It is specially designed for maximum performance and comfort under the often difficult conditions when mounted directly on the human body.
Attention has been paid to the humidity problems that often occur in theatrical applications and to the light weight construction of the headband itself. A double vent protection system, a drop stopper on the tube, 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 6mV/Pa to match the level of the human voice to the general input sensitivity of most wireless transmitters. The noise floor of the Type 4066 is 26dB(A) re. 20 mUPa and if powered correctly the microphone will be able to handle sound pressure levels up to 144dB 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.
