Drawmer DS101 features the frequency conscious gating functionality of the DS201 22/01/13
The Drawmer DS101 is the first noise gate module designed specifically for the 500 Series rack system. The DS101 is the first product in the 500 Series form factor from Drawmer, the company that, in 1982, introduced the world's first frequency conscious noise gate, the DS201, which went on to become a professional audio industry standard.
TransAudio Group, U.S. distributor of Drawmer professional signal processing products, is exhibiting the DS101 at booth # 6945 (Hall A) at the 2013 NAMM Show in Anaheim, CA.Here's their full description of it:
The DS101 is based on a single channel of the DS201 and incorporates the fully variable high- and low-pass filters and "key listen" monitoring functionality pioneered by Drawmer that enable frequency conscious gating. The new DS101, which can be used for both gating and "ducking" (for voice-over applications or the elimination of unwanted transient artifacts), incorporates comprehensive envelope controls -- threshold, attack, hold, decay and range -- plus a host of other features, including Drawmer's "traffic light" metering. The module's low-noise circuitry also incorporates Drawmer's proprietary hysteresis or "trigger stabilization," which prevents "chatter" around the threshold level.
When installed next to each other in a 500 Series rack, two or more DS101 gates may be linked using Drawmer's new infrared triggering mechanism. Linked in this fashion, the envelope shaping capabilities of any number of DS101 gates (up to a maximum 10 units in a single rack enclosure) may be independently adjusted while the trigger pulse passes through unchanged. This enables the user to achieve an almost limitless range of "envelope follower" effects. The DS101 additionally allows external triggering via a front panel 1/4-inch key input connector.
