DUAL MIC LINE INST PREAMPLIFIER
email: [e-mail] call:[phone]website: www.drawmer.com
The 1972 Dual Mic, Line & Instrument Pre-Amplifier has been developed to make it ultra easy for
you to capture perfect recordings every time. The 1972 gives you the ability to record pristine
audio from a variety of sources and especially makes the most of the multitude of microphones
that you find in the studio, from budget to high-end dynamic and also ribbon mics. Uniquely it
has added features that help out in difficult to record situations that are not found on other
preamplifiers.
The 1972 uses the latest THAT Corporation technology in the two independent mic preamps to
provide ultra clean, transparent and precise recordings, that can be processed at a later stage
using your favourite methods, be it compression, E.Q., saturation, valve, transformer or tape.
Each channel is capable of 66dB of stepped gain, with an additional +/-12dB’s trim at the output,
and incorporates switchable mic impedance for accurate mic matching to bring out the best
from any microphone used, and also provides a way to “sculpt” the sound of passive dynamic,
and especially low-impedance ribbon microphones.
Capture Difficult Sources
As well as standard features that you will find on most preamplifiers, such as phase reverse, the
1972 also has a wealth of tools that help when recording difficult sources, making it possible to
get the best quality recording with ease. These include fully variable LoCut and HiCut controls to
allow you to tune into recordings and remove superfluous signals in the low and high
frequencies, removing rumble and hiss with ease. In addition the Shape feature allows you to
bring out the bass or treble using a subtle tilt EQ.
Record Very Low Signals with Ease
A unique feature that has been developed by Ivor Drawmer and currently only available on the
1972 is the Lift control. Lift is essentially a low level dynamic gain module which has no effect on
signals above 0dB. This makes it possible to record very quiet signals in a transparent and
natural way without distortion and clipping taking place on the louder passages, and is
especially effective for very dynamic signals, finding great use in recording piano, and on all
vocals, including speech, and for capturing ambiance.
Be Creative using Variable Mic Impedance
You may have encountered the general rule that the impedance of the preamp input should be
10X that of the mic to get an input impedance that is appropriate for the mic and to avoid
loading the source, however, it is less known that mismatching can create some interesting
tonal differences that can be used more creatively. The 1972 has 3 settings per mic input: 200,
600 and 2400 Ohms, making it easy for you to explore the various tones. The result will depend
on the microphone used, as the tonal changes will be obvious with some mic’s but others will
hardly alter, and on the material you're working with.
