The Drawmer DS404 is a sophisticated four channel noise gate incorporating a number of features pioneered by Drawmer, which are invaluable to the sound engineer, and not found on conventional noise gates.
  • variable high pass and low pass filters for "frequency conscious" gating
  • auto attack, variable release
  • switchable hard/soft gating
  • key input for external triggering
  • "key listen" facility
  • extremely fast attack time, to preserve the natural attack of the sound
  • balanced inputs and outputs
  • stereo linkable
  • Drawmer "traffic light" status meter

These features and its "user friendliness" are based on the best of the "industry standard" DS201.
