EASYFLEX EZB SERIES MICROPHONES

OVERVIEW

Shure Easyflext EZB Series microphones are small, surface mounted electret condenser microphones designed for mounting on conference tables, stage floors, and lecterns. Their wide frequency range makes them especially suitable for picking up speech and vocals in sound reinforcement and recording applications.

FEATURES

S Flat frequency response across the vocal range for uncolored sound.

S Sleek, low-profile design for unobtrusive appearance.

S In-line preamp reduces visible size of microphone

S Available in either cardiod or omnidirectional models

MODEL VARIATIONS

EZB/C: EZG series microphone with cardiod polar pattern.

EZO/G: EZG series microphone with omnidirectional polar pattern.
