COSI, Long cage, mike diam. 19mm (4017C)

Product

The COSI principle means that the windproof material that lines the cage is not removable. There are cages with a fur or fabric finish, but it is impossible to add an additional fur to the fabric!

However, this constraint results in simplification of the windshield. The same goes for all the other choices for an immediate and versatile use on a pole or camera:

Medium thickness furring (+/- 30mm)
Adaptation to a wide variety of microphones thanks to five cage lengths and seven “Holders” of different diameters.
Cables and Holders totally removable and interchangeable, as needed.
The COSI is naturally less windproof than a larger windshield, but certainly more than any other windshield of comparable size. The very high level of isolation from handling noise makes the COSI exceptionally easy to manipulate.

Ideal adaptation: DPA 4017C (short body preamp). Long cage, mic diam. 19mm

Can be adapted to the DPA 4017B (“medium” preamp) by allowing the XLR to protrude at the rear.
The microphone is no longer completely fixed in the holder, which is held in place only by friction. Care must be taken, however, to respect the ideal positioning of the acoustic part inside the cage.
