Three switchable Attack settings are provided giving Fast, Medium and Slow attack times. The same degree of gain reduction is applied to both audio channels to prevent image shifting which would otherwise occur whenever the left and right signal dynamics varied from ddrawmer other by any significant degree. Disconnect the unit from the mains.
A major advantage of the hybrid approach schematiic that it combines the reliability and stability of modern solid-state designs with the warm, detailed sound of vintage classic tube designs.
Traditional moving coil meters are used to monitor either the gain reduction or the output signal level while an output Gain control provides up to 20dB of make-up gain. For your own safety it is important that you use this cable. Isn’t it a optical comp? I have had many on the bench that had dirty pots. Setting up is simplified by the soft-knee compressor action which means that it is only necessary to adjust the Threshold control until the desired degree of gain reduction is achieved.
April 24, Select the appropriate signal source for each channel using the selector switch. Hope this helps – the symptons seem to be identical to the unit i had to repair!
Check your wiring if using sidechain jacks. Make sure that the pots are solid.
Passive equaliser control, which can be set to provide up to 15dB of bass boost at 40Hz. In Stereo Link mode, both channels track together to avoid the inevitable image shifting that would occur if the two channels of a stereo signal were treated independently.
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.
Replace with a correctly rated fuse for the selected operation voltage. 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 19960 guitar amplifiers.
Rectified this and put more new tubes – rdawmer solved!
Johan Member Sweden Posts: A two position high or low gain switch provides an additional 10dB of gain when required for level matching or for creating overdrive effects. 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.
Balanced operation is recommended. There is little doubt in the minds of many engineers and producers that vacuum tubes possess a unique sound quality providing a “warmer, more alive” sound. I find it interesting that both the channels have failed I swapped many TLs with low offset chips to adress that problem.

Johan on May 29, Switchable Attack and Release settings are provided along with a fully variable Threshold, two of the Release settings being programme dependent.
Rdawmer linked mode, the compressor controls should, ideally, be set to schrmatic same settings as the control-circuitry for both channels responds to the average between the two channel settings.
Do you know the age, and have you contacted Drawmer? The two auto release switch settings continually optimise the compressor action to suit the dynamics of the material being processed, setting 5 drawmed optimised for percussive material and setting 6 for general purpose use. Using a number 1 size pozidrive screwdriver, remove the two self-tapping screws holding the voltage selection switch cover plate on the rear panel. Avoid mounting the unit directly above scchematic amplifiers or power supplies that radiate significant amounts of heat and always connect the mains earth to the unit.
Switch settings 1 through to 4 provide progressively increasing release times, while positions 5 and 6 cause the release times to vary in a manner which automatically adapts to the dynamics of the incoming signal.

Started by tonebucket The Lab. The microphone input stages feature extremely low noise, balanced input circuitry with additional tube amplification, enabling modern microphones to take on the characteristics of older tube models. 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.
As an instrument amplifier, the provides gain, EQ and compression making it ideal for DI’ing guitars, basses and even keyboards.
