With an incredibly user-friendly interface and a reputation as an industry standard in noise gating, the DS201 from Drawmer is an innovative dual-channel noise gate, providing sophisticated noise attenuation facilities such as gating, ducking, and AHD (attack, hold, decay) envelope control as well as threshold, range, and bypass control. The DS201 offers loads of functionality with the ability to accept gate triggers from internal and external sources (via the 1/4" insert) and can use external signals to not only control the gate and use one sound to gate another, but it can also be used simply as a filter through the Key Listen function.
Variable low- and high-pass filters allow for frequency-dependent gating effects, and the maximum attack time of the DS201 is exceptionally fast, within microseconds, allowing you to preserve the natural attack of your signals. Classic Drawmer traffic-light metering provides clear indication of the gate and threshold status, and each channel has its own meter and balanced I/O, allowing you to process two independent signals or one stereo-linked signal. This unit includes an AC power cord to get you started.
Drawmer's solution to this problem is the inclusion of two variable filters, one high-pass and one low-pass, which act upon the sidechain keying circuitry. By setting the output switch to Key Listen, the user can hear the action of the filters and adjust them to reject high-frequency spillage from the hi-hats. This now enables the gate to only open on the lower frequencies present in the snare drum.
