DRAWMER / 1972 Mic/Line/Instrument Preamp

A 2-channel mic/line/instrument/preamp with unique low/high cut and shape functions, lift control, etc., making it even more versatile.

The 1972 uses the latest THAT Corporation technology on two independent microphone preamps to provide you with extremely clean, transparent and accurate recordings that you can later process using any method you prefer: compression, EQ, saturation, valve, transformer, tape, etc. Each channel is capable of 66dB of graduated gain, has an additional +/-12dB of trim on the output, and incorporates switchable microphone impedance for precise mic matching, allowing you to get the best performance from the microphones you use. It also provides a way to ""sculpt"" the sound of dynamic and low impedance ribbon microphones.

Capture difficult sources
In addition to the standard features found on most preamps, such as phase inversion, the 1972 also has a wealth of tools to help you when recording difficult sources, making it easy to get the highest quality recordings.

Fully variable LoCut and HiCut controls are included, allowing you to tune into your recording and remove excess low and high frequency signal to easily eliminate rumble and hiss. Additionally, the Shape feature allows you to bring out the bass or treble with a subtle tilt EQ.

Record low-level signals with ease
A unique feature developed by Ivor Drawmer and currently only available on the 1972 is the Lift control. Lift is essentially a low-level dynamic gain module that has no effect on signals above 0dB. This allows you to record very quiet signals in a transparent and natural way without distortion or clipping during louder phrases. It is especially effective on very dynamic signals and is ideal for recording all vocals including piano and speech, as well as capturing air.

Variable Mic Impedance
The general rule is that the impedance of the preamp input should be 10 times the impedance of the microphone to get the right input impedance for your microphone and avoid loading the source, but what is less known is that a mismatch can produce interesting tonal differences that can be used more creatively. The 1972 has three settings for each microphone input - 200, 600 and 2400 ohms - making it easy to explore different tones. Results will vary depending on the microphone you use. Some microphones will have a clear change in sound quality, while others will have very little change. It also depends on the material you use.
