Discontinued Products: CTM-77

The CTM 77’s smooth bandwidth of 50-18kHz coupled with the high output of -55dB make it a first class live sound microphone. The CTM77, a high quality electret condenser, provides exceptional clarity for singers and close application vocals, yet its’ low proximity effect and excellent gain before feedback make it a solid choice for business and podium use, as well. The CTM 77 includes the Astatic (I.N.R.-3™) Impact Noise Reduction System shockmount which isolates the microphone capsule from the body, dramatically reducing cable, stand and handling noise, and also a rugged Flex-Form™ hardened grille screen. The CTM 77 will operate with phantom power sources from 9-52 volts. The on/off switch on the CTM 77 can be locked in the on position. The CTM 77LS is switchless.
