The Electro-Voice CO2E/CO2EX is an omnidi-
rectional back-electret condenser lavalier mi-
crophonedesignedforthebroadcastandsound
reinforcementapplicationswhereacousticfeed-
back problems are minimal.
The frequency response of the CO2E/CO2EX
microphoneprovidesafull-range,well-balanced
sound character for clean and accurate sound
reproduction.Themicrophone’somnidirectional
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).
FIGURE 1 — Frequency Response
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

POWERING AND OPERATION OF THE
CO2/CO2EX
The CO2E may be powered by an external
phantom power unit or via a wireless transmit-
ter. The CO2E is equipped with stripped and
tinned leads.
The CO2EX is powered by the external wire-
less transmitter through the attached TA4F
connector.
