Resumen del manual
The wide and flat frequency response of the CTM 44 provides unsurpassed natural transparent sound quality. The cardioid pickup pattern minimizes annoying feedback (when used close to sound 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 44 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 44 will maintain its attractive appearance. The CTM 44 uses a high energy neodymium magnet. The low-frequency response of the CTM 44 may be enhanced by increasing or decreasing the distance from the sound source. This phenomenon is technically known as “proximity effect”. Nominal 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 44 includes an on/off switch and is supplied complete with a zippered vinyl protective pouch and a snap-in microphone swivel-mount. ASTATIC Quality All CTM 44 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 44 is one of the finest values in sound reinforcement and recording microphones available. Although it is incredibly durable, it should be stored in the zippered pouch provided 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 and remove the inside foam windscreen. Wash the foam windscreen using a mild detergent, and let dry thoroughly. Follow the same method for the grille screen. To clean the mike housing, use a cloth dampened with isopropyl alcohol.
