The in-house design team at the South Windsor, Connecticut facility along with the aid of some of the industry's most knowledgeable and respected consultants , developed the CU-29 Copperhead from the ground up. Each CU-29 microphone comes complete with M900 power supply, M800 25’ tube microphone cable, M700 elastic shock mount and wooden microphone box.
The R-F-T Series of tube condenser microphones utilizes American designed electronics in conjunction with New Old Stock (NOS) vacuum tubes and standardized parts from overseas manufacturers. Just like the Diamond Series, all R-F-T Series microphones are hand-built in TELEFUNKEN Elektroakustik’s South Windsor, Connecticut facility. With this line, TELEFUNKEN Elektroakustik is able to provide a lower cost alternative to more expensive microphone systems, without sacrificing the qualities that would be expected from a TELEFUNKEN Elektroakustik microphone.
This fine-tuned amplifier design found in the CU-29 "Copperhead" features a NOS TELEFUNKEN 6AK5W vacuum tube and a Lundahl LL1935 output transformer. Being a cardioid only microphone, the R-F-T CU-29 "Copperhead" employs a single-membrane version of the TK67 large diaphragm capsule used in the AK-47 MkII microphone, which undergoes rigorous testing in our laboratory prior to installation.
Sonically, the CU-29 "Copperhead" is a remarkably hi-fidelity microphone that provides a warm, clear low end complemented by a smooth, detailed high end. The CU-29 “Copperhead” is an excellent multi-purpose microphone that sounds great on drums, electric guitar, vocals, bass, piano and a countless number of other applications.
