CTM-55B/CTM-55BLS Commercial Audio Products Description DYNAMIC SUPERCARDIOID MICROPHONE The CTM-55B is a dynamic supercardioid microphone designed for professional vocalists and musicians. The CTM-55B provides the performance and features to satisfy today's most demanding professionals. The wide and flat frequency response of the CTM-55B provides unsurpassed natural transparent sound quality. The supercardioid pickup pattern minimizes annoying feedback (when used close to reinforcement speakers and monitors) and reduces the pickup of unwanted off-axis sounds. An effective internal multistage pop filter minimizes wind and breath noise. The CTM-55B has a Flex-Form™ hardened steel grille screen that dramatically resists deformation while greatly reducing any risk of adverse performance caused by a bent or dented ball screen. This unique ability to retain its original shape assures that the CTM-55B will maintain it's attractive appearance. The CTM-55B screen is painted a durable soft feel midnight black. The CTM-55B is also available without a switch (CTM-55BLS) The CTM-55B utilizes the proprietary Astatic (I.N.R.-2™) Impact Noise Rejection system. A rubber shock mount isolates the transducer from the body, thus dramatically reducing cable, stand and handling noise. The need for any external shock-mounting device is virtually eliminated. The low-frequency response of the CTM-55B may be enhanced by increasing or decreasing the distance from the sound source. This phenomenon is technically known as "proximity effect". Normal or "flat" response is generated at a distance of 24 inches or more. However, as the distance to the sound source decreases, the bass sensitivity increases, providing a solid robust character. The CTM-55B is supplied complete with a zippered vinyl protective pouch and a microphone swivel clamp. 50.5mm (1.988) 166mm (6.535) Astatic Quality All CTM-55B microphones are audio tested and inspected prior to shipment. Our absolute commitment to quality insures that Astatic microphones remain the best value in today's competitive industry. Operation and Maintenance The CTM-55B is one of the finest hand-held vocal microphones available at any price. Although it is incredibly durable, it should be stored in the provided zipper pouch to protect it from dust and dirt when not in use. If the front screen becomes soiled by dirt or residue, it may be cleaned using the following procedure: Unscrew the front screen assembly, remove the inside foam windscreen, wash using mild detergent, and let dry thoroughly. Follow the same method for the outer grille screen. To clean the mike housing, use a cloth dampened with isopropyl alcohol.
