The Astatic by CAD CTM 77LS is a low-noise, electret condenser cardioid microphone designed for professional vocalists and musicians. The CTM 77LS microphone provides performance and features that satisfy today's most demanding audio professionals.
The CTM 77LS mic's wide and flat frequency response gives you 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. A transformerless electronic design provides optimum low frequency response and low distortion. An effective internal multistage pop filter minimizes wind and breath noise.
The Astatic CTM 77LS microphone 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 77LS mic will maintain its attractive appearance.
The Astatic by CAD CTM 77LS mic features the exclusive (I.N.R.-3TM) Impact Noise Rejection system. The rubber shock mount isolates the transducer from the barrel, thus dramatically reducing cable, stand, and handling noise. This virtually eliminates the need for an external shock mounting device.
Astatic supplies the CTM 77LS microphone with a zippered vinyl protective pouch and a snap-in microphone swivel-mount.
