Alchemy Microphone Series Matched Stereo Sets
The TF29 Copperhead, TF39 Copperhead Deluxe, TF47 and TF51 microphone systems, now being offered in matched stereo sets, feature a custom dual power supply capable of powering both microphones at one time, as well as a locking flight case that contains two microphones, cables, and shock mounts. All the electronic components in each system are matched sonically and electronically, including matched capsules, transformers, and vacuum tubes.
TF47 Stereo Sets
The TF47 is a new design based on the “German” sound, drawing inspiration from the historic U47 and M49. With a deep low end and a forward midrange, the TF47 is excellent for adding depth and presence to any source. These characteristics make it especially ideal for recording vocals, guitar amps, and drums. The T47 delivers a warm and punchy sound reminiscent of the U47 with a pleasant top end articulation that easily sits in a mix.
At the heart of the TF47 is an all-brass K47-style capsule, new old stock 5840W vacuum tube, and custom-made historically accurate BV8 transformer (as found in the U47). These components deliver a warm and punchy sound reminiscent of the U47 with a pleasant top end articulation that sits perfect in a mix.
