Amber Technology

DPA’s headband mics are all equipped with a double vent protection system, sweat stopper on the tube and water resistant materials inside the capsule, which allow the microphones to operate reliably even in high-humidity applications. All DPA headset microphones are available in a choice of colours and sizes, and supplied with multiple windscreens.

With DPA headset mics, singers and speakers are free to use their hands and move around without compromising voice quality. A wide range of connection adapters makes it possible to use DPA head-worn microphones with all professional UHF, VHF or digital wireless systems available plus 48 V Phantom.

The 4066 headband construction is unique in design, offering both left and 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.

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 ear hooks 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.

Each 4066 is delivered with five foam windscreens.

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