CM-02  CTG Flush mounted Ceiling Microphone  conferencing Covert Discrete

Description

CM-02 CTG Flush mounted Ceiling Microphone conferencing Covert Discrete. Condition is "New". Shipped with USPS Priority Mail.
The CM-01 and CM-02 ceiling microphones utilize a special pressure sensitive, tensionless low-mass element enhanced with an integrated FET low noise amplifier. These characteristics result in ultra smooth frequency response providing excellent feedback stability for voice reinforcement and teleconferencing applications. The high temperature stability assures exceptional system performance in fixed gain situations. In an average acoustical environment this microphone will have a pickup range of 10′ – 12′ radius.
CTG listened to many requests to offer our acclaimed silver ceiling microphone (CM-01) in white and we now offer a white version of the ceiling microphone (CM-02).
