The DPA MMB4067-B Miniature Microphone Boom, Lo-Sens & DC, Black. Highly regarded by engineers, a boom and mic only option for those who do not require a headband.
The DPA MMB4067-B is a Miniature Microphone Boom and Omnidirectional Capsule, for use with the DPA AHM6001 Adjustable Headband. The 4067 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 microphone to fail. The sensitivity is 1 mV/Pa to match the level of the human voice to the general input sensitivity of most wireless transmitters. The DC offset in the FET is also lowered, making matching to systems delivering down to 3 V power supply possible. If powered correctly the microphone will be able to handle sound pressure levels up to 154 dB SPL before clipping occurs. A wide range of connection adapters makes it possible to use the 4067 with most of the professional wireless systems available plus 48 V phantom XLR connection.
The main features of the DPA MMB4067-B include:
Very high SPL capabilities for a miniature microphone
Flexible microphone used for speech and vocals in Broadcast, Stage and Television
For use with the DPA AHM6001 Adjustable Headband – not included
