DESCRIPTION AND APPLICATIONS
The Electro-Voice CO2E/CO2EX is an omnidirectional back-electret condenser lavalier microphone designed for the broadcast and sound
reinforcement applications where acoustic feedback problems are minimal.
The frequency response of the CO2E/CO2EX
microphone provides a full-range, well-balanced
sound character for clean and accurate sound
reproduction. The microphone’s omnidirectional
polar characteristic provides a uniform output
regardless of the direction of the sound.
The CO2E/CO2EX microphone is designed to
attach to the performer's clothing using the
supplied clips (See Furnished Accessories).
The microphone’s transducer is permanently
attached to the shielded miniature cable. The
cable is high-strength and flexible, designed to
withstand the rigors of professional use. The
exclusive Tincture™ surface accepts acrylic lacquer paint—to blend with any surface.
POWERING AND OPERATION OF THE
CO2/CO2EX
The CO2E may be powered by an external
phantom power unit or via a wireless transmitter. The CO2E is equipped with stripped and
tinned leads.
The CO2EX is powered by the external wireless transmitter through the attached TA4F
connector.
