The DN514 Plus from Klark Teknik is a four-channel gate, that provides frequency conscious gating along with sidechain key signal triggering. The Quad Auto Gate is designed to enable the studio or PA engineer to greatly improve the quality of sound sources quickly and simply, by gating out unwanted background clutter or tape hiss.
To simplify operation, two semi-automatic attack modes are selectable, with one dedicated to percussion. This eliminates the need for a rotary attack control. Hold time is scaled to the setting of the release time control, giving reliable gate closure without the "chattering" that often requires extended adjustment.
Frequency conscious gating allows the engineer to place microphones close to each other without each microphone triggering its gate from the other source. A Sync function makes it possible to interlock the release times of the four gates to synchronize harmony vocals, or a brass or string section. Key inputs allow gate triggering by sources other than the signal passing through the gate.
