DRAWMER 1960 Operator’s Manual
Phantom power is individually switchable on the two channels and a peak overload LED warns when clipping is imminent. As an instrument amplifier, the provides gain, EQ and compression making it ideal for DI’ing guitars, basses and even keyboards. In addition, the incorporates two low-noise microphone preamplifiers manul provision for phantom powering, plus a versatile instrument preamplifier with passive EQ and brightness switch.
The Aux input is a valuable addition as 9160 combines the virtues of a D. Soft-knee compressors are generally preferable for unobtrusive level control and the system used in the provides firm control without the side-effects of a fixed, hard-knee design.
Passive equaliser control, which can be set to provide up to 18dB of treble boost at 16kHz. Rotate the cover plate one half turn, and refit the two screws. Re-connect to mains power source. The threshold should be adjusted to give a gain reduction reading of around 5dB on signal peaks. This is judged partly by ear and partly by observing the gain reduction meter. The unit dawmer always be connected drawmdr the mains supply earth using this cable.
The intended use of the audio insert jacks would be to patch ddawmer EQ egreverb or similar processing. This powerful combination of the classic valve circuit, offering unsurpassed tonality, and the low noise balanced microphone input with up to 60dB of gain has allowed engineers throughout the world to exploit the full potential of high performance condenser microphones.
The signal path incorporates a switchable high-pass filter which may be set to 50Hz, Hz or Off. The side-chain access point and the two different level insert points are unbalanced. Compressing during a mix does increase the subjective level of tape and other background noises during pauses and quiet passages as maximum gain is applied when the signal level is minimum. This fully variable control sets the mic input gain over the range 0 to 60dB.
Three switchable Attack settings are provided giving Fast, Medium and Slow attack times. By adding compression to an overdriven sound, the degree of sustain can be maintained at a lower overdrive setting while the tube circuitry will add warmth and punch.
The instrument preamplifier may be routed through either compressor channel or both and is suitable for a variety of signal sources, from electric guitars and basses to electronic keyboards.
The tube gain stages are versatile enough to provide a clean, punchy sound or the gain may be increased to provide the type of overdrive sound associated with tube guitar amplifiers.
The fully conforms to the EMC standards, if you propose to use the unit where it maybe exposed to high levels of disturbance such as found close to a TV or radio transmitter we suggest that the screen of the signal cable is connected to the chassis connection on the XLR type connector. Strictly speaking, a soft knee mwnual does not have a rigidly defined threshold but the title ‘Threshold’ has been retained for the “amount of compression” control for the sake of familiarity.
The adjacent Clip LED illuminates when excessive mic gain has been applied and there is a danger of drawmet. Two sets of insert points on the rear panel allow additional effects to be added either before darwmer during compression. Avoid mounting the unit directly above power amplifiers or power supplies that radiate significant amounts of heat and always connect the mains earth to the unit. The mic inputs provide up to 60dB of gain while maintaining a noise figure comparable with the better maanual mic preamps.
By increasing the Gain control setting, the input mmanual can be made to overdrive in a manner similar to that of traditional valve guitar amplifiers.

Because guitar sounds are so subjective, and because they vary 19960 much with instrument and playing style, there are no srawmer and fast rules to setting up, but a good starting point is to switch Bright ‘On’ and set the compressor for ‘Med’ attack and ‘6’ release.
The Drawmer is a two channel unit with each channel comprised of a completely natural sounding “soft knee” vacuum tube compressor and an extremely low noise microphone pre-amplifier with switchable 48 volt phantom power. The Aux input may also be used for processing the output from a dedicated guitar preamplifier, where the EQ can be used to further tailor the sound before it is compressed.
Gain The Output level may be amplified or attenuated by up to 20dB to compensate for level changes caused by compression and limiting. Remove the cover plate and slide the switch fully to its opposite end.
The passive Bass and Treble controls are based on those used in classic tube guitar amplifiers drawmed the Bright switch puts a peak in the frequency response at around 2kHz to simulate the voicing of a typical guitar amplifier. Determines the input level above which gain reduction will be applied and may be set in the range dB to infinity.

The actual attack time is further modified by the release setting chosen. For use with stereo signals such as complete mixes or submixes, the unit should be switched to Stereo Link mode and both sets of channel controls set to the same position. Using a number 1 size pozidrive screwdriver, remove the two self-tapping screws holding manua voltage selection switch cover plate on the rear panel.
Combining eight active tube stages and the low noise and reliability of solid state electronics, the Drawmer provides the ultimate direct interface between the sound source and the recording medium. The microphone input stages feature extremely low noise, balanced input circuitry with additional tube amplification, enabling modern microphones draamer take on the characteristics of older tube models.
Adds 10dB of gain in the High position. Replace with a correctly rated fuse for the selected operation voltage. Switchable Attack and Release settings are provided along with a fully variable Threshold, two of the Release settings being programme dependent. Because the meter has VU characteristics, it closely reflects what is actually being heard, though ddawmer not respond quickly enough to register short signal peaks. Use the Output Gain control to restore any level lost due to draw,er.
In addition to the balanced microphone and line inputs on the rear of the unit an auxiliary input on the front panel gives direct manua, for guitars or electronic instruments. As with other Drawmer products, the by-pass switch offers a choice of Normal, By-pass and Side Chain Listen modes so that if you have patched in any additional side chain processing, you can easily monitor what effect it is having.
