Miniature : 4061-FM

Miniature Omnidirectional Microphone, Lo-Sens, Beige

4061-FMThe Type 4061-F is the beige version of the Miniature Microphone Type 4061. This type is a prepolarised omnidirectional Miniature Condenser Microphone with a 5.4 mm vertical diaphragm specially designed for maximum performance under the often difficult conditions when mounted directly on the human body. Special attention has been taken in the design to deal with the humidity problems that often occur in theatrical applications. A double vent protection system together with water resistant materials inside the microphone make it more than difficult for moisture to cause the Miniature Microphone to fail. By changing the protection grids, the Miniature Microphones can furthermore be acoustically modified according to the placement of the microphone on the body. Type 4061 is acoustically identical with the award winning Type 4060, but the sensitivity is adjusted to 6mV/Pa to match some of the more sensitive transmitters on the market. The noise floor of the Type 4061 is 26 dB(A) re. 20 µPa and 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 4061 with close to any professional wireless system available plus 48 V phantom.
