Drawmer 1970 Dual FET Compressor & Pre-Amplifier

Drawmer 1970 Dual FET Compressor & Pre-Amplifier

The 1970 Dual F.E.T. Compressor and Pre-Amplifier builds on a heritage inspired by the first pro audio “tool box” compressor, the illustrious Drawmer 1960, but with a greatly expanded feature set, making it one of the most adaptable mic preamplifier/compressors on the market today. Bringing vintage audio characteristics at an affordable price.

Whilst the feature set of the 1970 is similar to the Drawmer 1960, and the layout of the controls will add to the comparisons, the 1970 has been greatly improved and the D.I. EQ has been fine tuned to be more accurate than its stable-mate, with various enhancements.

From tracking instruments via the dedicated D.I. input, to recording vocals via the ultra clean mic pre’s, recording a guitar cabinet with two microphones, or a singer playing guitar, or even stereo buss compression using the comprehensive linking and mix facilities, the 1970 is the perfect versatile tool for any studio or live event.

The 1970 use the latest THAT Corporation technology in the 2 mic preamps to provide ultra clean, transparent and precise recordings that can be processed at a later stage using your favourite warming method, be it saturation, valve, transformer or tape. In addition each channel is capable of 66dB of gain, with switchable mic impedance for accurate mic matching to bring out the best from any microphone used. Phantom power, phase reverse and a high pass filter are also included.

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 1970 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.

The dual compression section includes threshold, ratio, attack and release controls, along with Drawmer’s exclusive Big and Air features on each channel and can be used as two separate mono tracking compressors or a stereo buss compressor using a link switch.

If desired the 1970 can provide an ultra clean microphone signal via the THAT Corporation mic amplifiers by utilising the fully balanced hard-wire bypass which connects the input source directly to the output without passing through the compressor FET’s, the mix and gain controls at all.

Incorporated into each channel of the 1970 are the ‘Mix’ Controls. They act like a ‘parallel compression’ effect that mixes the Wet (compressed) and Dry (original) signals to provide a simple and exact way of controlling the amount of compression used – all with the turn of a single knob.

One criticism of compressors is that it is possible to take the effect too far and ruin a mix – this is easily prevented with the 1970 by the use of the Mix control just by mixing in less of the wet signal and more dry. By the same token, the mix control can add more compression simply by adding more of the wet signal. It’s that simple!

Features:

• Two THAT Corporation ultra clean mic pre’s with 66dB of gain with phantom power and switchable mic impedance for accurate mic matching.
• Separate Line & Mic input XLR’s.
• A pro quality instrument DI input with low and high EQ.
• Can be used as 2 mono tracking compressors or 1 stereo buss compressor (avoiding image shifting) via the class leading comprehensive linking facilities.
• FETs can be bypassed altogether to provide ultra clean outputs.
• Standard controls such as Threshold, Ratio, Attack & Release, with 8 LED GR Metering on each band.
• Rear panel Side-chain insert points provide even further control.
• ‘Big’ and ‘Air’ Modes Help to preserve the very deep lows and Enhance the sparkling highs.
• Variable Wet/Dry Mix plus Output Gain knobs on both channels give a ‘Parallel Compression’ function without the need for external mixing devices, providing complete and effortless control over the amount of compression used and output levels.
