CA 2204004

A microphone system includes a portable frame for mounting linear pick-up microphones such that each of the microphones has its diaphragm facing outwards from the frame and the diaphragms form a generally elliptical pattern. A microphone with a substantially hemispherical pick-up pattern is mounted on the frame such that it is directed upwards and a second substantially hemispherical pick-up pattern microphone is mounted on the frame directed downwards. The linear pick-up pattern microphones are equispaced about the perimeter of the frame. There is a hand or camera grip depending downwards from the frame. The microphones of the frame can be electronically connected to the channels of a multi-channel digital mixer which in turn can be connected to a multi-channel sound recording device. The microphones may be selectively electronically connected and disconnected to adapt the system for a predetermined sound playback configuration.

Un système de microphones comprend un support portable servant à fixer des microphones de type linéaire de sorte que la membrane de chacun des microphones soit orientée vers l'extérieur à partir du support et que les membranes créent un volume généralement elliptique. Un microphone de type sensiblement hémisphérique est monté sur le support de sorte qu'il soit orienté vers le haut et un second microphone de type sensiblement hémisphérique est monté sur le support orienté vers le bas. Les microphones de type linéaire sont équidistants sur le périmètre du support. Une poignée de caméra solidaire du support s'étend vers le bas. Les microphones du support peuvent être connectés électroniquement aux canaux d'un mélangeur numérique multi-canal qui peut être à son tour connecté à un dispositif d'enregistrement sonore multi-canal. Les microphones peuvent être connectés et déconnectés électroniquement afin d'adapter le système à une configuration de restitution sonore prédéterminée.
