DRAWMER / 1972 Mic/Line/Instrument Preamp

This 2-channel microphone/line/instrument/preamp features unique low/high cut and shaping functions, as well as lift control, making it more versatile.

The 1972 uses the latest THAT Corporation technology with two independent microphone preamps to deliver exceptionally clean, transparent, and accurate recordings. These recordings can then be processed later using your preferred methods, including compression, EQ, saturation, valve, transformer, and tape. Each channel offers 66dB of stepped gain, an additional +/-12dB of trim at the output, and built-in switchable microphone impedance for precise microphone matching, allowing you to extract the best performance from your microphone. It also provides a way to ""sculpt"" the sound of dynamic and low-impedance ribbon microphones.


Capturing Difficult Sources


In addition to standard features found in most preamps, such as phase inversion, the 1972 also includes a wealth of tools to help you record challenging sources, making it easy to achieve the highest quality recordings.

Fully variable LoCut and HiCut controls are included, allowing you to tune into your recording and easily eliminate excess low and high frequencies, removing rumble and hiss. Furthermore, the Shape function allows you to bring out bass or treble using subtle tilt EQ.


Easily Record Low-Level Signals

Developed by Ivor Drawmer, the Lift control is a unique feature now only available on the 1972. Lift is essentially a low-level dynamic gain module that does not affect signals above 0dB. This allows you to record very quiet signals in a transparent and natural way without distortion or clipping in large phrases. It is particularly effective for very dynamic signals and is ideal for recording all vocals, including piano and speech, and capturing the sense of atmosphere.


Variable Microphone Impedance

While there is a general rule that the preamp input impedance should be 10 times the microphone impedance to get the right input impedance for the microphone and avoid overloading the source, it is less well known that mismatches can produce interesting tonal differences that can be used more creatively. The 1972 has three settings per microphone input: 200, 600, and 2400 ohms, allowing you to easily explore a variety of tones. The results will vary depending on the microphone used. This is because some microphones show a clear change in sound quality, while others show almost no change. It also varies depending on the material used.
