DRAWMER
CONTROL DESCRIPTION
The DS101 noise gate incorporates many
impressive features, many 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, with ‘Key listen’
facility.
• Comprehensive envelope control, attack, hold,
decay and range.
• Ultra-fast response time.
• ‘Traffic light’ display giving clear indication of
gate status as well as Threshold Metering.
• Key input for external triggering.
• Linking. Each DS101 can be linked to another
whilst still retaining independent envelopes.
• Can be used for "Gating" or "Ducking".
• High audio specification.
These features are based on the industry
standard, DS201 Noise Gate manufactured by
Drawmer since 1981.
The Gate Controls
Threshold Infinite to -62.0dB
Sets the level below which gating starts to take
place. For normal noise removal applications,
it is usual to set the Threshold as low as is
possible without spurious triggering occurring,
so that none of the desired signal is lost. The
meter above clearly shows the threshold level
in response to the actual signal.
Attack 10uS to 1S
Controls the speed that the gate opens. The
fastest Attack time ensures that the gate does
not clip the leading edge of extremely fast
signals.
Hold 2mS to 2 Seconds
Determines the amount of time the gate is held
open after the signal falls below the Threshold.
This helps to prevent spurious re-triggering
when using fast Release times, but is also
instrumental in creating the classic gated reverb
sound which is often applied to drums.
