DPA Microphones 2011A

Popis

Tento model je postavený na inovativní dvojmembránové technologii “Twin Diaphragm” s interferenčními trubicemi, vyvinuté firmou DPA. Vyniká čistým a dynamickým zvukem a je vhodný jak pro studiové nahrávání tak i pro ozvučování (je velmi robustní). Mikrofon je součástí modulární série DPA Reference Standard, takže lze vhodně kombinovat s dalšími vložkami a předzesilovači z této série. Mikrofon je vybavený standardním studiovým tělem mikrofonu (typ A).

The DPA 2011 Twin Diaphragm Cardioid Mic is a directional microphone. The distinctive sound of this microphone is well balanced. It bridges the gap between the extreme sound quality of our pencil microphones and our well-known Lavalier microphones.

Two opposite-facing miniature capsules are custom rebuilt inside this microphone. They are placed into a double-diaphragm, one-capsule composition. This combines the advantages of small capsules with the lower inherent noise achieved from a larger diaphragm area. These capsules provide fast impulse response and large frequency bandwidth. The capsules are loaded to our supreme preamps, which gives the sound more air and precision.
