Shure Easyflex 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.
• Flat frequency response across the vocal range for uncolored sound.
• Sleek, low-profile design for unobtrusive appearance.
• In-line preamp reduces visible size of microphone
• Available in either cardioid or omnidirectional models
EZB/C: Cardioid polar pattern.
EZB/O: Omnidirectional polar pattern.
The microphone shall be a small surface-mounted electret condenser microphone, with options for a cardioid
or omnidirectional polar pattern. The microphone shall have wide frequency response and a high sensitivity, making it ideal for use in challenging sound reinforcement and recording environments. The microphone shall include
an external preamplifier.
The microphone shall be designed so that it can be either set in place temporarily, or securely installed. The
microphone shall be available in both white and charcoal gray to blend with any surrounding.
The microphone shall be of the Shure Easyflex EZG series.
