DS101

Transparent Noise Gating
Removes unwanted noise and spill while preserving the natural character of the original performance.

Frequency-Conscious Gating
Variable high-pass and low-pass sidechain filters let the gate respond only to the frequencies you choose, reducing false triggering from unwanted sounds.

Key Listen
Allows you to monitor the sidechain filter so it can be tuned quickly and accurately for reliable gate operation.

Complete Envelope Control
Independent attack, hold, decay, and range controls provide precise shaping of the gate's response for any source.

Ultra-Fast Attack
Opens in microseconds to preserve fast transients and maintain the natural attack of instruments and vocals.

External Key Input
Accepts an external trigger signal, allowing one source to control the gate on another for creative and practical processing.

Infrared Module Linking
Multiple adjacent DS101 modules can be linked while each retains its own envelope settings, making stereo operation and creative multi-channel processing simple.

Independent Envelope Control
Linked units share the trigger signal but maintain separate attack, hold, decay, and range settings for flexible channel shaping.

Gate and Duck Modes
Operates as either a traditional noise gate or a ducker, making it suitable for voiceovers, broadcast, click removal, and level control.

Envelope Shaping
Can reshape the attack and decay of sounds, tighten drum hits, clean up samples, and create gated effects.

Trigger Stabilisation
Proprietary hysteresis technology prevents chatter around the threshold for smooth, reliable gating.

Traffic Light Metering
Clear visual indicators show whether the gate is open, closing, or closed for quick status monitoring.

500 Series Design
Brings Drawmer's industry-standard noise gate technology to a compact single-slot 500 Series format.

Based on the DS201
Built from the proven design of the renowned Drawmer DS201, delivering the same professional gating performance in a 500 Series module.
