Astatic CTM-55B Specification Sheet

Commercial Audio Products
Description
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.

Our absolute commitment to quality insures that Astatic microphones remain

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.
