OVERVIEW
Shure Easyflext EZG and EZG-SE Series microphones a re
miniature gooseneck-mounted electret condenser microphones designed primarily for speech and vocal pickup. They
can be mounted on lecterns, pulpits, or conference tables. All
models include a preamplifier and are available with cardioid
cartridges. EZG-SE Series microphones can be screwed onto
a microphone stand or the supplied 5/8 inch, 27 threaded
flange. They c an b e e asily c hanged f rom s ide-exit t o b ottom-exit
to conceal the cable.
S (SE) 5/8–27 threaded nut with cable exit provides a
variety of mounting possibilities.
