Noise Gate. Operates like an audio switch,
and is particularly suited to percussive signals,
where it can shape the envelope to create a
crisp, well defined signal.
Gate/Duck switch. When Duck is selected,
the operation is reversed, so that when the
signal is above threshold, the output is
attenuated. Below Threshold, the signal
passes un-attenuated.

The SDX100 provides either a Noise Gate or
Expander. Use the Noise Gate to shape the
envelopes of percussive signals, such as drums.
For vocals or other expressive signals, the
Expander may be better suited to the task, since
it can track the signal levels instead of simply
switching on and off.

Main Features

Left and Right input levels.
Linear Input (-32dB to 0dB) and Output (-62dB
to 0dB) VU meters.
Knobs for quick parameter control. All
thresholds and levels are in linear dBs, but
other controls are scaled to a user friendly
law which minimizes ‘fine tuning’ and allows
a wide range of operation.
Triggering. Click on to toggle selection of
trigger sources. In Stereo mode, the gate can
trigger from either the Left or Right channels,
a mono signal generated Left + Right Envelope
Controls, as well as external trigger sources.
Control the speed at which the Gate opens
and closes.
Compressor/Limiter incorporating “Bootstrap”

About Drawmer





The name Drawmer is synonymous with professional signal processing in recording studio, broadcast
and live sound reinforcement environments. The company which is based in Yorkshire, England was
founded by Ivor Drawmer whose passion was designing audio circuits.

Products that have been developed by Drawmer include the revolutionary DS201, the world’s first ‘frequency
conscious’ noise gate, as well as the 1960 Mic Pre-Amp/Vacuum Tube Compressor, the DL241 Auto
Compressor and more recently the highly rated Masterflow DC2476 Digital Mastering Processor.

In 1999 the influential contribution of Ivor Drawmer to pro-audio design over the last 20 years was recognised
by the APRS (Association of Professional Recording Studios). The Association presented him with a
coveted Award for Lifetime Technical Achievement to the Audio Industry.
