Description

T-12 Microphone Kit

The T-12 is a stunning vocal microphone in DIY kit form. Intermediate-level hobbyists can build it in two to three hours. The kit provides a genuine vintage microphone circuit (based on a Neumann design) with a selected large-diaphragm capsule (based on the AKG capsule from the C12, ElaM 251, and C414). The finished microphone delivers great tone and vibe, with a frequency response that complements vocals, acoustic guitars, and drum overheads.

About the Circuit

Transformer microphones just sound different. This particular circuit yields a warmer, rounder sound than you d get from a transformerless circuit.

The beneficial 2nd harmonic coloration from the circuit is not due to components we added, though; this mic has what might be the simplest audio signal path in any microphone:

Capsule → JFET → Capacitor → Transformer

We chose each of those parts with care: hand-selected capsule, manually biased NOS JFET, polypropylene output capacitor, custom transformer.

Greg Wells Review

Greg Wells is credited with 85 million units sold (including Adele). Here s what he says about the T-12:



The SonicScoop Review

SonicScoop.comPaul Womack of SonicScoop built and reviewed the T12. It is a great review — detailed and clear, with descriptions of both the build process and the results. Here is a sample:

Now that I’ve done a number of male and female vocal sessions with the T-12, I can say that the top end is very smooth, but I’ve been equally as impressed with the midrange. It has a very solid sound: vocals stand right up in the mix. Not in a peaky way, but in a very full and up-front sounding manner.

The Pherotone Studios review

We can t get enough of Mark s review video. He seems very pleased with the mic. 🙂

Visual Color Choices

The T-12 comes standard with a matte black painted finish, with our popular vintage style diamond MP logo badge. We usually have some custom powdercoated color options available for a small additional cost; find those here.

The grille, for all body color options, is a 2-layer brass mesh with satin nickel finish.

About the Body (and switches)

The body has no external switches. This microphone has two internal switches, one for pattern (C O) and one for pad. To access the switches, spin the end cap off of the bottom of the mic, and slide the body sleeve down.

It is best to unplug the mic from phantom power before opening the mic.

Frequency Response

T12

The RK-12 capsule used in the T-12 is characterized by a broad but mild high-frequency boost. In our acoustic sweep tests, the T-12 exhibits a very slightly boosted top end, approximately 1dB higher in output than a U87 Ai. But where the U87 Ai rolls off the top aggressively above 12kHz, the T-12 has more air in that top octave.

We have included comparisons with the Mojave MA-201 FET, which uses a similar circuit (single JFET transformer topology), although with a different capsule type and size (32mm K67). On our test rig, the MA-201 has a slight scoop (-1dB) in the mids as compared to the T-12, and its high-frequency peak is slightly sharper, and occurs at a higher frequency (around 12kHz).
