Shure MX395B/C

Micro bouton à effet de surface et capsule électret destiné aux salles de réunion et conférence. Son extrême discrétion est un atout lorsque le critère esthétique d'intégration est primordial. Capsule issue de la série haut de gamme Microflex. Il intègre un préampli avec sélecteur coupe-bas, immunisé contre les interférences dues aux GSM. Fourni avec écrou de fixation et anneau d'isolation caoutchouc. Dimensions : Ø 2,5cm, H 2cm. Couleur noire. Cardioïde.
