Noise gating is a powerful technique for improving the clarity of a mix, whether in music PA work,
conference PA, or in the studio. But as the number of channels in multi track recording increases, and as the
microphone arrangement used in live sound becomes more complex, so the noise gate rack increases in size
and takes longer to set up.
The Klark Teknik DN514 Plus Quad Auto Gate has been designed to enable the studio or PA engineer to
greatly improve the quality of sound achievable, by gating out unwanted background clutter or tape hiss,
quickly and simply. The configuration of four gates per nineteen inch rack unit doubles the normal noise gate
packing density.
Noise gates have traditionally been difficult to set up correctly to give dependable triggering and to give
optimum background noise reduction. The
Quad Auto Gate uses intelligent design to reduce the
time spent in setting up.
Two semi automatic Attack modes, one dedicated to percussion, eliminate 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
'jitter' that can often take careful adjustment of controls to remove.
A feature important to the live sound engineer, where microphones may be placed close to each other and pick
up instruments other than the one intended, is Frequency Conscious Gating. A low frequency and high
frequency rotary controls on each channel tune the keying circuitry of the gate to a precise frequency range.
The gate only opens for the intended instrument and not when the microphone picks up sounds of other
frequencies from neighbouring instruments.
The Sync function is similar to the channel link on conventional stereo noise gates, but here it is possible to
interlock the release times of four channels of gating to synchronise harmony vocals or a brass or string
section. Key inputs allow gate triggering by sources other than the signal passing through the gate. A Side
Chain Monitor switch allows the engineer to monitor the Key signal, whether internal or external, and to
monitor the effect of the gate's filters.
Lights provide visual confirmation of gate open/closed status, and also allow monitoring of the Release
profile. A gate bypass switch is provided for each channel, and also a master bypass to facilitate setting up.
