Sound Pure's Take

The Kahayan 12K72 is a high-end dual-channel microphone preamplifier and line driver designed to deliver the iconic, thick analog character of classic 1970s British discrete console designs—specifically Neve's legendary 1272 line amplifier module—in a modern, rack-ready chassis. Built by hand in Spain by Kahayan Pro Audio, the 12K72 uses discrete Class-A circuitry and custom-wound transformers to add immediate weight, dynamic authority, and rich harmonic warmth to any signal path.

What sets the 12K72 apart in a crowded field of Neve-style preamps is its dual operational personality. While it functions as a pristine tracking front end with up to $+65\text{ dB}$ of stepped gain, its dedicated line-level inputs allow it to double as an analog insert or mix bus color box. Running full mixes, stem submixes, or digital synth tracks through the 12K72's Class-A transformer path imparts authentic vintage console glue, rounding off harsh digital transients while enhancing sub-bass depth and mid-range density.

The Kahayan 12K72 is a outstanding choice for engineers seeking authentic vintage British console tone in both tracking and mixing applications. Whether capturing lead vocals with deep proximity weight, dialing in thick drum tracking, or passing stereo mix buses through custom transformers to eliminate digital edge, the 12K72 delivers effortless Class-A character and boutique build quality.

From Kahayan Pro Audio

The 12k72 is a high class preamplifier which contains a ‘module’ per channel. The main feature of these ‘modules’ is a sound completely clear and transparent, with deep bass and an extremely natural treble.

The components used in manufacturing come essentially from the same manufacturers that supplied the ones used originally, reproducing and expanding the benefits of these. Everything inside this preamplifier is high quality: the wires, rotary switches, capacitors, resistors and connectors.

​

The benefits that this module offers, besides the already known sound merits, are:

  • Two mic / line independent preamp working in pure class A.
  • Using discrete technology (without IC's) with Carnhill® Transformers.
  • Gain control in steps of 5dB.
  • Output Level Control in steps of 1dB.
  • Phantom power 48v with pilot light.
  • Phase reverse switch.
  • Microphone / Line Switch (Also useful in line mode for mastering or mixbus processor).
  • Inputs and outputs: balanced and unbalanced (XLR and jack).
  • External high quality Power supply.
  • Front input jack for connecting high impedance electric instruments (guitar, bass, synth, etc.).
