Presented as the first noise gate designed specifically for 500 series rack enclosures, the DS101 from Drawmer is essentially a single-channel DS201, providing sophisticated noise attenuation facilities such as gating, ducking, and AHD (attack, hold, decay) envelope control as well as threshold, range, and bypass control. Taking up only a single 500 series slot, the DS101 offers loads of functionality in minimal space, and with the ability to accept gate triggers from not only internal and external sources (via the 1/4" insert) but also from the innovative infrared optical link, you can link up to 10 noise gates together, each with independent envelope control, opening up new possibilities for gate processing your mixes.

Variable low- and high-pass filters allow for frequency-dependent gating effects, and the maximum attack time of the DS101 is exceptionally fast, within microseconds, allowing you to preserve the natural attack of your signals. The classic Drawmer traffic light metering provides clear indication of the gate and threshold status. The Key Listen function simplifies the process of tuning out unwanted rattles, mic leaks, and rumbles, and the proprietary trigger stabilization technology eliminates the chatter sounds often heard around the threshold in lesser gates.

Sometimes, certain signals and microphone setups can prove tedious and problematic to noise gate. For example, if a gate is applied to a snare drum, a hi-hat can often unintentionally cause the gate to open, resulting in the hi-hats bleeding into the snare mic, while attempts to reign this effect in through the threshold can result in a failure to capture the light snare hits, ruining a performance.

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.

In normal operation, the filter only affects the way the gate responds (opens) to the incoming program material; it does not have any direct effect on the output signal. But when Key Listen is enabled, the effect of the key filter on the program material is heard at the output and the audio signal is not routed through gate. Normally this is used to monitor the effect of the filter to assist in tuning into the specific key source sound, but it can be used as a bracketing filter, making it simple to remove unwanted frequencies without using the resources that a more complicated equalizer would utilize.
