Fully featured noise gate based on the industry standard DS201. Takes up a single 500 series slot. Proprietary Hysteris or “trigger stabilization” to prevent “chatter” around the threshold. Fully variable high pass and low pass filters for “frequency conscious” gating. Comprehensive envelope control, attack, hold, decay, and range. External triggering via key input or the new IR trigger pulse from another DS101. “Key Listen” facility. Extremely fast attack time, to preserve the natural attack of the sound. Linkable - up to ten units in one rack space - with individual envelope shaping. Drawmer “traffic lighting” metering. Can be used for “Gating” or “Ducking”. Low noise design.
