Features 6AK5W vacuum tube Lundahl LL1935 output transformer Single-membrane version of the large diaphragm capsule used in AR51 and AK47MKii Description Product Description The Telefunken CU-29 Copperhead is a hi-fidelity microphone that is great for vocals, acoustic instruments, guitar amps, drums, and anything in between. With a wide array of sources it shines on, TELEFUNKEN Elektroakustik has developed the CU-29 "Copperhead" Stereo Set. The Stereo Set comes in a custom locking flight case that carries both sets of cables, shockmounts, microphones in wooden boxes, and a dual-channel power supply unit. This newly designed dual-channel supply can power one or both of the microphones at the same time. This upgraded power supply is a superior regulated design with a slow-ramping heater voltage to ensure vacuum tube longevity. The amplifier in the CU-29 "Copperhead" features a new old stock TELEFUNKEN 6AK5W vacuum tube, Lundahl LL1935 output transformer, and a single-membrane version of the large diaphragm capsule used in the AR-51 and AK-47 MkII. Each of these components is rigorously tested in our laboratory prior to installation. The microphone provides a warm, clear low end complemented by a smooth high end, with a delicate and intimate "air" to it. Each component for the two microphones is hand-selected for matched pairs. The capsules have matched frequency responses, the tubes have matched gain and noise specs, and the amplifier circuits have matched gain and frequency response. You can be sure that you will get identical responses from each microphone for the most accurate stereo imaging. With the CU-29 "Copperhead" Stereo Set, you have twice the versatility of the single unit for nearly any application.
